Netflix has detailed an upgrade to its Android app which should reduce buffering and make audio sound better and easier to hear over background noise. It’s been made possible thanks to the adoption of the xHE-AAC codec, which a Netflix blog post says should “improve intelligibility in noisy environments, adapt to variable cellular connections, and scale to studio-quality.” Netflix’s use of the codec was announced earlier this month, and is available on devices running Android 9 and above.
xHE-AAC uses metadata to solve a few different audio problems people have when watching shows on mobile devices. Netflix explains this is often a problem of loud background noise making content hard to hear, combined with weak and tinny phone speakers that sound bad when you try to put up the volume. Inconsistent dialogue levels also mean you have to constantly turn your volume up and down between shows.
Netflix says xHE-AAC offers better Dynamic Range Control, a technology that reduces the difference between the loudest and quietest parts of a show. Quiet content is made louder so you can hear it over background noise, and the volume of loud content is brought down to prevent clipping, all in theory without sacrificing audio quality. Netflix also says that the volume of dialogue is kept consistent between shows.
Finally, the codec also supports “seamless bitrate switching,” which means it should work better in environments with inconsistent internet speeds. Netflix added similar adaptive bitrate functionality to its TV apps back in 2019.
Netflix says that user testing has demonstrated the benefits of the codec. Volume changes between content are “noticeably down” and viewers switch away from using their phone’s built-in speakers 7 percent less often with the new codec. Netflix says it hopes to bring the codec to other platforms that support it. For those keeping track, iPhones have supported xHE-AAC since the release of iOS 13 in 2019.
Looking to upgrade your home working environment? You could do a lot worse than a pair of Klipsch ProMedia 2.1 BT powered speakers. Updates on the company’s ProMedia 2.1, now with Bluetooth for wireless playback from a phone, tablet or laptop, they promise to blast our your background music or Zoom calls much better than your computer’s speakers will.
Each satellite speaker in the pair, which would nicely flank a computer or laptop, houses an 8cm Klipsch MicroTractrix horn mid-bass driver directly below the 19mm PEI (polyethermide) tweeter – an arrangement Klipsch claims produces sweet treble and a natural midrange from a small footprint. They’re joined by a separate 17cm side-firing, ported subwoofer that can be tucked out of the way. Together, they kick out 200 watts of power – not bad for desktop computer speakers of their size.
The Klipsch ProMedia 2.1 BT speakers are available in the UK now, priced £279.

Fresh from launching its unusual Sport Open Earbuds, Bose has turned its attention to updating two of its Bluetooth speakers. Say hello to the SoundLink Revolve II and SoundLink Revolve+ II, successors to the – you guessed it – Bose SoundLink Revolve and SoundLink Revolve+.
The new Revolve II (pictured below) now offers 13 hours of battery life from a single charge – up from 12 hours in the original – and although the new variant looks remarkably similar to its older sibling, you now get an IP55 rating for protection against dust and water ingress.

The SoundLink Revolve+ II (pictured top) delivers a higher volume and more room-filling sound than SoundLink Revolve II, and this model now boasts 17 hours on a single charge.
Both speakers are available to buy now, priced at £179.95 for the Bose SoundLink Revolve II and £279.95 for the larger Bose SoundLink Revolve+ II. That makes them fierce competitors for the What Hi-Fi? Award-winning Audio Pro Addon C3 and Addon C10 wireless speakers, as well as the Bang & Olufsen Beosound A1 (2nd Gen), so needless to say we look forwarding to seeing how they stack up.

Q Acoustics bravely enters uncharted waters, but out-of-character sonic shortfalls let down an otherwise decent first effort
For
Thoughtfully designed
Vast hub connectivity
Punchy, room-filling sound
Against
Lacks dynamic and rhythmic expression
No dedicated control app
Stands are expensive extras
It’s a simple fact of life that the more there is to do, the more there is to prioritise. For Q Acoustics’ first all-in-one streaming speaker system, the Q Active 200, the British speaker specialist could have focused most of its attention on the streaming side of things – that is the unchartered territory here, after all. While the brand has some degree of experience in powered speaker design, this is its first proper active streaming proposition.
But the Q Acoustics Q Active 200 appear to be a speaker-first design, given the ambitious acoustic engineering on show here. Get the speaker part right, as you’d hope a firm with such plaudits in the field would, and you’re halfway there.
Build

If you were expecting an active set of speakers resembling Q Acoustics’ current range of standmounters, then the Q Active 200’s design may raise a few eyebrows.
The boxes are narrow, deep and in a beautifully finished matte white – so far, so Q Acoustics. But instead of the usual tweeter and mid/bass woofer decorating each façade, there is a rectangular grille in the top corner that hides two round, 58mm BMR (balanced mode radiator) drive units.

It gives the classy cabinets a unique, neatly minimalist look that might sit well in contemporary designed living spaces – but the design is likely to divide opinion.
Q Acoustics has chosen to use a pair of BMR drivers in each cabinet in preference to conventional cone units. BMRs have two big advantages: they deliver both midrange and treble (and a bit of bass) from their modestly sized forms, so avoiding the need for a separate tweeter and mid/bass combination and the distortion generating crossover that goes along with it. And they also radiate sound uniformly across a 180-degree plane, reducing the usual tendency for speakers to create a listening ‘sweet spot’.
The drivers’ diminutive size, extended frequency response and wide-dispersion talents make it a practical choice for a product such as the Q Active 200.
Their positioning on the speaker – the dual BMR configuration can sit either on the inside top corner or outside top corner, depending on which way round the speakers are placed – brings some benefits too. According to Q Acoustics, the asymmetry in the acoustic path lengths from the BMRs to the baffle edges improves diffraction characteristics. It also offers flexibility in positioning: for far-field listening (further away or to the sides) they should be positioned to the inside, or for near-field listening, on the outside.
Of course, there’s only so much quantity and depth of bass a 58mm driver can dig up, which is why Q Acoustics has integrated a ported 11.4cm woofer into the rear of each cabinet. This brings driver cooperation and crossovers back into the mix, but Q Acoustics has carefully considered that.
The upper BMR (each BMR has its own DSP and amplification channel) operates the full frequency band from the crossover point with the woofer to 20kHz, whereas the lower BMR is designed to only work up to 5kHz. The woofer fires onto a rear baffle, its output guided through vents at the side of the cabinet, with sophisticated DSP keeping the sound from all the drive units time aligned.
Whereas the floorstanders in the Q Active range, the Q Active 400, use the P2P bracing as primarily engineered for the company’s Concept 300, these standmounts adopt a ‘dart bracing’ technique, which fixes the rear-firing woofer directly to the front of the cabinet to provide it with mechanical stability.
Q Acoustics has designed a pair of dedicated stands for the Q Active 200, the Q FS75, more modest evolutions of the innovative stands designed for the Concept 300. For an extra £350 ($499) per pair, they feature a skeletal, highly rigid ‘space’ frame made up of rods in compression, stabilised by cables in tension, and have fixings that enable them to be bolted to the standmounters.

Q Acoustics has taken the decision not to house the streaming architecture and connectivity inside the speakers, but instead in a separate connectivity hub. There are two hub options to choose from, depending on where your voice control loyalties lie. The Google Home box (which we have on test) offers Google Assistant voice control, plus built-in Google Chromecast, while the Amazon Alexa box variant works with Alexa.
It’s a shame one box doesn’t cover both bases – there must be plenty of people who use Alexa, for example, but also stream music via Chromecast. And what if your allegiance changes down the line? Q Acoustics says it’s looking into making each hub individually available, though hasn’t yet confirmed its plans.
Whichever hub you choose, you get the same physical inputs – HDMI (ARC), optical, and an analogue input that is switchable between line level and moving magnet. Essentially, that means everything from a CD player to a TV to a turntable can be connected to the hub and streamed to the speakers. Digital signals from the HDMI and optical inputs are all converted to 24-bit/96kHz, as are analogue signals through the 24-bit analogue to digital converter (ADC).
Rather than the hub streaming these converted signals to a master speaker that passes the other audio channel to the slave speaker, it sends the two channels of audio directly to the speakers over a 5GHz wireless connection, helping ensure accurate syncing between them.
The hub is also a streaming gateway to AirPlay 2 for iOS users, Spotify Connect for Spotify Premium and Family subscribers, and Bluetooth. Support for the Roon music platform is on the way via a future firmware update, too.
If you own a NAS drive with music, UPnP support is onboard for playing networked music files up to 32-bit/192kHz (which subsequently gets down-sampled to 24-bit/96kHz for the transmission to the speakers). Q Acoustics will soon release its dedicated Q Active app for helping owners with registration and set-up, control hub customisation, software updates and basic controls, however it won’t be an all-encompassing music control app from which to browse networked or local music libraries and access streaming services.
That’s a shame, but third-party UPnP control apps aren’t hard to come by, and those using Tidal (via Chromecast) or Spotify (via Connect) may well choose to use the native apps anyway. For accessing our NAS device, we use the free MConnect and BubbleUPnP apps on an Apple iPad and Samsung Galaxy S20 phone during our testing and both work fine.
Alternatively, there’s the compact RF remote control for adjusting volume, pause/play, skipping tracks and changing inputs. A strip of touch buttons across the rear of each speaker’s top panel more or less mirrors remote control, too. They’re nicely responsive – sometimes more so than the UPnP apps we use – although as there’s a short delay in the call and action, we would have liked visual confirmation of the communication from, say, a visible LED. There is an LED by the controls on the top panel that flashes to signify this, but unless you’re standing you won’t be able to see it.

Q Acoustics has successfully built a reputation for excellent passive speakers in its 15-year history – especially in the budget market. Its products have consistently included class-leading clarity and entertaining punch, and those talents have predictably found their way into the Q Active 200 too.
We play Radical Face’s The Missing Road from Tidal via Chromecast, and the melodic acoustic strums, cello and vocal humming come through with an eager lucidity, the presentation startlingly clear and direct, not to mention room-filling. You shouldn’t necessarily expect Q Acoustics’ typical richness and warmth here, but the active speakers’ leaner, more forward tonal stance gives them a likeable sense of snappiness.
We stream over Bluetooth and, though we expect the usual drop in quality, the Q Active 200 keep things surprisingly tight, losing a bit of solidity and space compared with UPnP and Google Chromecast playback, but largely proving a worthwhile method of playback.
The BMR drivers keep their end up, spreading sound generously and evenly around our test room and ensuring the speakers produce an impressively big presence for their compact footprint. They have the volume and punch to make easy work of John Williams’s climactic compositions, and while that rear-firing woofer is limited in terms of absolute bass depth, it proves taut and terse as the bassline in SBTRKT’s Wildfire (played over UPnP) comes into play. Bass blends in nicely with the rest of the frequencies, too, proving Q Acoustics has done a good job with the crossover between the BMRs and low-frequency driver.
To help optimise positioning, each Q Active 200 has three settings selected by a manual switch at its rear. There is ‘Positioned close to a corner’, ‘Positioned close to a wall’, and our preferred ‘Free-space’, which we find works best not only when the speakers were out in the room, but also near the back wall – possibly because the speakers’ bass output isn’t overbearing and the midrange is a little forward. As always, we’d recommend experimenting to see which setting works best in your listening room.
We switch from Q Acoustics’ dedicated stands to a pair of Custom Design FS104 Signatures and the presentation sheds some clarity – from both a sonic and aesthetic point of view, we’d recommend the custom-built accessory. But, while the Q FS75 extracts more from the speakers, the overall differences aren’t huge. Just note that due to the rubber strips beneath the speaker, secure placement on a third-party pair of stands may be a little fiddly.

There’s a bit of harshness in the upper mids, which remains audible even after a week of use. It’s not the end of the world, but it does mean higher-pitched voices can start to grate after a while. It does nothing for a dense, cymbal-heavy track like Touché Amore’s I’ll Be Your Host either.
But our biggest issue with the Q Active 200 is their combined lack of dynamic and rhythmic expression. With Nick Cave and The Bad Seeds’ Galleon Ship, the piano and vocal pairing comes through clear and solid, yet is bereft of real feel.
Everything seems to ride along one audio plane, lacking forward momentum and dynamic tiers. It doesn’t help that the sound staging isn’t particularly well layered either. Together, these things mean the track isn’t all that interesting or emotionally grabbing.
Whether trying to grasp the grooves that underpin Thundercat’s Them Changes, or nail the rhythmic logistics integral to the SBTRKT track, the Q Active 200 don’t quite tie the musical strands together with the coordination necessary for them to thoroughly entertain. They conduct themselves in a startlingly clear and upfront manner, but beyond that they fail to captivate.
Offering an entire audio system inside such a compact and convenient concept is no easy task, but those such as the KEF LSX and KEF LS50 Wireless II, which sandwich the Q Acoustics in price, show it can be done. The Q Active 200 ultimately fall well below those standards, delivering a cruder listen than we’d expect at this not-insignificant price.
Verdict
It’s rare, if ever, that we publish sentences featuring both ‘Q Acoustics’ and ‘disappointing’, but here the Q Active 200 cannot hide behind their thoughtfully considered spec sheet and speaker engineering. It’s a shame because the brand has done a lot right – there’s vast connectivity on offer, a whole lot of speaker engineering, and dedicated stands for those who want them. But performance-wise, they simply aren’t entertaining enough to recommend.
It’s often the case that first efforts are followed by better second ones, and we very much hope that turns out to be the case here.

KEF has released an absolutely tiny (246x256x248mm) powered subwoofer, KC62, that uses three new KEF technologies to deliver unprecedented levels of deep bass.
“KEF’s new 1,000-watt KC62 subwoofer surpasses traditional expectations of what a subwoofer can achieve based on its size,” said Nigel Ng, of Advance Audio, which distributes KEF in Australia.
“KEF’s engineers have used proprietary patented force-cancelling and Uni-Core technologies in a brand new approach to subwoofer performance, allowing maximum bass in a minimum space, so that the KC62 delivers unprecedented depth and breath-taking accuracy.”
Best subwoofers for music and movies
The two cones of a KEF Uni-Core driver share a common magnet assembly (Image credit: KEF)
Uni-Core technology combines force cancellation with a single enormous magnet and two completely different concentrically arranged voice coils (one for each driver). KEF says the Uni-Core technology allows cabinet size to be reduced by over a third while equalling or exceeding the driver excursion of a much larger subwoofer.
The two 165mm diameter driver cones are fitted with what KEF calls ‘P-Flex’ or ‘Origami’ surround suspensions. “P-Flex is a brand-new patent-pending driver surround that resists the acoustic pressure inside the cabinet without limiting sensitivity in the way traditional half-roll surrounds do,” says Ng.
“KEF also calls this an ‘Origami’ surround because its shape and appearance are so evocative of the Japanese art of paper folding.
Whichever name you’d like to to use, the result is the same: it allows the drivers to move with greater excursion, resulting in deeper bass extension and more accurate bass reproduction with vastly reduced distortion.”
The new KC62 also uses KEF’s patent-pending ‘Smart Distortion Control Technology’ which is a unique sensorless, motional feedback system that corrects even the slightest signal abnormalities and transients.
“Essentially the circuit continuously monitors the current in the voice coil, detecting, and then correcting any non-linear distortions,” says Ng.
The SDCT works in concert with KEF’s in-house designed DSP algorithms iBX (Intelligent Bass Extension) and SmartLimiter to ensure the two 500 watt Class-D amplifiers that power the drivers deliver the perfect signal.”

Versatile connection options include compatibility with KEF’s KW1 wireless adaptor kit, and KEF’s SmartConnect eliminates connection issues. There are five Room Placement Equalisation presets, allowing the performance of the KC62 to be optimised no matter where you put it in your room – next to a wall, in a corner, within a cabinet, or on display right out in the open.
A high-passed line output means it can be partnered with external powered speakers, such as KEF’s flagship compact LS50s.
Available in Carbon Black and Mineral White finishes, the KEF KC62 Uni-Core Force-Cancelling Subwoofer retails for £1400 ($1500, AU$2495).
Unpacking 2021 with a bang, we have the Samsung Galaxy S21 for you today. Samsung has rearranged its yearly release schedule to pull its high-end S-series reveal for January, and could there be a better way to kick off the year?
We did say ‘bang’, but it’s hardly the most thunderous of those – out of the trio of Galaxy S21 phones announced, we’ll now be presenting you the smallest, vanilla one. We also have the Ultra at the office, but you’ll need to wait a bit more for that – no event starts off with the headliner anyway.
For the second year in a row, Samsung unveils three phones as part of the spring flagship roster (even though it’s very much winter this time around, at least where we are). And, much like last time, there’s a very clear divide between the ultimate uncompromising Ultra and the two more restrained and down-to-earth ‘regular’ S phones. If anything, the gap has even widened.
The examples are plenty, some of them more significant than others. Take the displays for example. Unlike last year when all three phones had 1440p resolution panels, now only the Ultra gets the higher resolution, the ‘mainstream’ S21s stand at 1080p. All three screens were curved in 2020, now it’s just the Ultra. All three S20s had the same high-refresh rate implementation, now the Ultra gets a more advanced Adaptive mode than the other two.
How about the cameras? The S20 Ultra had a vastly superior setup than the other two, regardless of issues it might have had with realizing the full potential of all of its impressive hardware. Well, the S21 Ultra builds on top of that and comes with further improved internals in the imaging department. The S21 and S21+, meanwhile, reuse last year’s bits. Hmm.
But there’s more. In the case of the small Galaxy S21 we have here, a final blow hurts the most – it’s got a plastic back. It’s hardly the end of the world, and we’ll go on to rationalize how that’s actually a good thing on the next page. But it goes to emphasize the further differentiation between the one true flagship and the others that stand below it. And then further down below it.
Some genes are shared among all in the family, after all. The chipset is the same on all three (still different from region to region, but that’s a whole other topic), all have the second-gen ultrasonic fingerprint reader from Qualcomm, as well as stereo speakers and IP68 rating for dust and water resistance. And no, none of them has a microSD slot, that one was most surprising.
Here it is, the high-end Galaxies’ new and improved (read ‘smaller’) retail box. Following in the footsteps of Apple, Samsung has chosen to remove the charger and headphones from the retail bundle, resulting in a more compact box.
Yes, yes, you’re supposed to already have chargers at home, so not including one with every phone should help reduce waste, plus the decreased shipping volume will lower the carbon footprint along the logistics chain. It’s a noble concept though somehow saving the environment still doesn’t feel like the key driving factor.
Having said that, at the S21 keynote, Samsung mentioned that adapters will now be sold at a reduced price, and this seems like a step in the right direction.
Anyway, what you are getting in the box is the phone itself and a USB-C-to-C cable. That sort of means you need to have a moderately contemporary USB PowerDelivery charger lying around, or a USB-A-to-C cable if you intend to use an adapter that doesn’t have a Type C out.
As it came to light around the iPhone 12 launch days, local regulations in France specifically mandate that all phones sold in the country come with a headset. So S21s in France will indeed ship with the usual set of AKG-branded earbuds we’ve gotten used to from Galaxies in recent years. Still no charger, though.
Philips has introduced a new monitor model called 288 E2UAE. The device is equipped with 28 – inch, 10 – IPS bit panel with 4K resolution (3840 x 2160). In addition, the product is characterized by a minimalist design and narrow frames. The device is based on the already mentioned IPS matrix with wide viewing angles characteristic for this type of screens, displaying 1, 07 billion colors. The panel also has an sRGB palette coverage of 119, 7%. Also worth mentioning is the SmartContrast technology that will automatically adjust the brightness of the backlight and the level of contrast depending on the type of content displayed. The MultiView function allows you to connect two devices simultaneously, e.g. a desktop computer and a notebook.
Philips 288 E2UAE is a 4K monitor priced at 1490 with an IPS matrix, which has several aces up its sleeve, incl. possibility of connecting two sources.

Spotify wants to offer companies the possibility of switching data-supported and data-controlled podcast advertising in the future. In addition, the advertisers should receive information about the effect achieved by their advertising. The advertising format “Spotify Podcast Ads” and the advertising control tool “Streaming Ad Insertion” (SAI) will be available in Germany in the future.
The According to Spotify’s announcement, it is a problem for advertisers with podcasts that users download them and it is therefore often unclear whether they have heard the advertising audios placed in the episodes. Since Spotify only allows its paid customers to download podcast episodes, the “Streaming Ad Insertion” tool should be able to close this knowledge gap and provide information about the frequency of advertising calls. In this way, the companies would find out more about their target groups and receive data on the effect of their advertising measures.
Support in placing and creating advertising Spotify announces that advertisers will be offered various options for placing their advertising in almost all podcast episodes: immediately before a podcast episode is played, during the episode specified in the podcast Place or after its end. Spotify also helps with the creation of advertising and provides a network of professional speakers – if the podcast host doesn’t even speak the advertising message.
According to Spotify, there is a continuously growing range of podcasts: Of the 320 million Spotify users, 22 percent listen to podcasts on a regular basis. Overall, there is a big trend towards audio streaming.
A future function of AirPods Max may be the possibility of replacing the headband with new models. There are several clues that make you think, starting from the teardown made by iFixit
of Nino Grasso published on 21 January 2021 , at 14: 01 in the Apple channel Apple
The headband of the AirPods Max , the very expensive Apple headphones with cancellation noise, can be removed with very little effort by the user. The particular feature of the new Apple device was disclosed by iFixit, which carried out the usual teardown revealing that the operation can be performed with a tool we all have: the pin for removing the SIM , present on all smartphones sold in recent years.
AirPods Max are over-ear headphones that have already done the talking for many aspects, including audio quality and customization possibilities, as well as the exorbitant price compared to other comparable products for the consumer market. The part that encloses the pads is magnetically attached, and you can buy new pads to get a great variety of possible color combinations, for your personal version of AirPods Max.
L Any future possibility of replacing the headbands with after-market products would significantly increase the customization possibilities for Apple headphones. As revealed by iFixit it is in fact possible to remove the headband without performing any disassembly operation : they must be removed the pads, fold the earpads and insert the SIM removal pin into a small hole positioned just above one of the speakers.
Will there be after-market headbands for AirPods Max in the future?
The operation it serves to “compress two small springs inside the joint”, thus freeing the clamp that holds the earpads and headband hooked. In doing so, a connector similar to Lightning (but smaller) is exposed which is used to transfer data and power between the two headphones. The user can replace the headband with that of other AirPods Max to obtain new color combinations not initially foreseen by the manufacturer, in a much easier way than expected.
The novelty is rather curious because the possibility of customizing the headband was announced by several rumors , before the launch of the AirPods Max, but it seems that it has been removed on the final product. The relative simplicity with which the operation can be carried out, however, suggests that Apple really thought about the “feature” and then eliminated it later to simplify and speed up production work, as Bloomberg had said.
It is possible that the simplified headband removal system is reminiscent of the original AirPods Max design, and that in the future Apple could use it to introduce an ecosystem of headbands to replace the originals. It is also possible, however, that Apple has kept the system only and simply to facilitate the repair works, even if it seems a stretch given the way in which the system is developed, too refined to be thought for the insiders.
At the moment, however, we absolutely recommend that AirPods Max owners do not do the operation, as it is not clear whether the procedure invalidates the product warranty.
(Pocket-lint) – Bang & Olufsen makes some of the best looking and best-sounding speakers on the market, Bluetooth and otherwise. There are a couple of ranges within B&O Play’s lineup: BeoPlay and BeoLit, with the BeoLit name dating all the way back to 1939. Quite the heritage.

B&O Beosound A1 (2nd Gen)
squirrel_widget_239630
With a slightly awkward renaming of the excellent BeoPlay A1, the Beosound is B&O’s latest portable Bluetooth speaker, and it’s a real doozy. Bringing down the starting price of the speaker while cleverly and subtly updating its design, it offers a compelling package.
The one drawback to the speaker is that it really mainlines on the Bluetooth side of things – there’s no Wi-Fi here, or AirPlay, so you’re dependent on that Bluetooth for everything. That’s no different to the original, though, and you get the extremely useful additions of both Alexa support and waterproofing, the latter the real key to its upgraded success in our eyes. There’s also a bigger battery, giving 18 hours of use per charge.
With its sleek metal body and leather strap, the Beosound A1 2nd Gen is about as good-looking as a portable speaker can get, too, with superb build-quality matching its impressive oomph and balanced sound. It’s a high-quality speaker for those looking for something a little more distinctive.

B&O Play, Bang & Olufsen’s lifestyle subsidiary, makes some of the best looking and best sounding speakers on the market, Bluetooth and otherwise. There are a couple of ranges within B&O Play’s lineup: BeoPlay and BeoLit, with the BeoLit name dating back to 1939, which is quite the heritage.

B&O Play BeoPlay P2
squirrel_widget_172064
One of the newer speakers in the BeoPlay 2 range, the P2 effectively replaces the older A2 speaker, which you’ll read more about below. It’s the result of some good iteration, shrinking the form-factor of the speakers without compromising on sound quality, and smoothing away some of the rough edges.
That iconic all-metal grille is still very much present and correct, along with a built-in loop for carrying, but the P2 could genuinely fit in a roomy pocket or handbag, rather than being slightly too big to carry around super easily, and as such is a real star for usability. It has a 10-hour battery to keep you going all day, and you can also use Siri from your iPhone straight through the speaker when you need to.

B&O Play BeoPlay P6
squirrel_widget_145767
Another one of B&O’s newer speakers is the BeoPlay P6. This uniquely designed speaker has a fairly science fiction-style look to it, and again prominently displays the metal grille that marks out a B&O portable. With an all-over design, the sound coverage is 360-degree, and helps the P6 to be a genuine room-filler from a volume and quality standpoint.
A raft of buttons on the speaker’s top let you control it as needed, although the companion app also lets you handle all of that from your smartphone if preferred. The P6 also has a battery that should last you for 16 full hours of playback, which is a really impressive life, and made even better by the fact that it’ll fully charge in just 3 hours.
An on-board microphone also makes the P6 useful for taking calls or ordering about Siri or the Google Assistant to take care of tasks. Sound-wise, a 4-inch woofer and two 1.5-inch full-range drivers take care of pinpoint reproduction.

B&O Play BeoPlay M3
squirrel_widget_172063
The BeoPlay range may have a range of portable speakers, and also a fair amount of unconventional design, the M3 is B&O Play’s potential answer to the traditional bookshelf speaker, and, as such, is a little more standard itself.
This is a gorgeous stationary speaker, mains-powered, with a small form-factor that doesn’t stop it putting out quality sound. It’s bigger sibling the M5 can be found further down this guide, but this smaller version is a powerful option. B&O says it’s designed to fill a “medium-sized” room, and the design means that it should melt into the background visually.
With a 3.75-inch woofer and 0.75-inch tweeter, the balance is great, and really comes into its own if you pair it with one or more other speakers (whether M3s or another type). The M3 is a great choice if you’re looking for a subtle, but exquisitely designed multi-room speaker that could work in a variety of home settings.

B&O Play BeoPlay A9
squirrel_widget_172066
The B&O Play BeoPlay A9 is very much an iconic B&O product, and is now in its fourth generation of internal specs. It looks just as much like a piece of furniture than it does a speaker. In fact, at first glance, you might not know it’s a speaker at all. Behind its round exterior you’ll find an 8-inch bass woofer, two 3-inch midrange drivers, two 1.5-inch full-range drivers, and two 0.75-inch, 80-watt tweeters.
The BeoPlay A9 has some cool tricks up its sleeve too. To turn the volume up or down you simply swipe your hand across the top of the speaker, or you can rest your hand on top for a few seconds to mute what’s playing. A tap of the right hand side will skip the track forward, while a tap on the left will skip it back. Finally, a short tap on the centre of the speaker will resume the last music source played.
With some modern upgrades, the A9 also now works with Google Assistant to provide smart assistant benefits, as well as packing AirPlay 2 for your connection needs. If you’re looking for a statement speaker that produces some delicious Danish sound – and have the money to back it up – the BeoPlay A9 is the speaker for you.

B&O Beosound Balance
squirrel_widget_192240
Right at the top end of B&O’s scale (and that’s a scale that goes to some pretty extreme places), the Beosound Balance is a simply gorgeous home speaker that won’t necessarily work for many people’s budgets, but will provide a premium experience for those who go for it.
We love the look of the speaker, its wooden base contrasting nicely with the fabric of the main unit above it, and that construction hides a full range of drivers that’ll pump out stunning sound. It’s got solid connections, especially since Spotify Connect is coming in an update, and if you’re looking for a home speaker that really stands out, it could be a great choice.

B&O Play BeoLit 20
squirrel_widget_3646129
The BeoLit 20 is the latest upgrade to a line that’s included the 17 and 15 before it, and makes some canny additions to an already lush design, including a wireless charging pad on its top-side to keep your phone topped up.
At this price, the lack of Wi-Fi connectivity is a bit of a drag, but for portable Bluetooth sound you won’t find much more high-fidelity options out there.
You can use the Beoplay app to configure the one-touch command button on top to carry out one of four different functions: Alarm, Connect, ToneTouch or Remote. Two BeoLit 20 speakers can be connected together to create a stereo pair and the battery once again provides up to 24 hours of playback.

B&O Play BeoPlay M5
squirrel_widget_139918
The BeoPlay M5 is a cylindrical speaker that fires sound out through a full 360-degrees. Inside it has a 5-inch woofer, a 1.5-inch midrange driver and three 0.75-inch tweeters, with each driver being given its own Class D amplification.
It can either be used on its own, where it is more than capable of filling a room with sound, or be used as part of a multi-room music system with other B&O speakers. You can connect them together via Google Cast or BeoLink Multiroom and there’s no limit to the number of speakers you can join together.
The top aluminium disc is used to control the source and volume levels and you can use the Beoplay app to calibrate the sound depending on where the speaker is positioned. This is a seriously nice-looking speaker, and it’s noteworthy that B&O were on the “all-fabric” look years before it went mainstream through the likes of Amazon.
SparkFun and Pimoroni, partners in the recent Raspberry Pi Pico project, have announced their own RP2040 ‘Pi Silicon’ based boards with extra features and changes to the Pico form factor. Pimoroni is also the first partner to have add-on boards available for purchase for release day. This follows announcements from Adafruit and Arduino, who are also releasing boards based upon the new RP2040 SoC. All of these new RP2040 boards have the same Arm Cortex M0+ CPU and 264KB of SRAM, but they each bring something unique to the table.

SparkFun’s Thing Plus shares the same form factor and basic pinout as Adafruit’s Feather RP2040, but hidden on the underside of the board is a micro SD card slot useful for larger project files or data logging projects, with 16MB of flash storage granting the SparkFun Thing Plus a large storage capacity. Thing Plus also has a JST battery charging port, 30 GPIO pins including four 12-bit ADC channels, SparkFun’s Qwiic Connect I2C sensor connection, and a WS2812 RGB LED. Thing Plus can be used with C/C++ and MicroPython.
Priced at $16 and available in mid-February, SparkFun’s Thing Plus is an interesting board for data logging and science experiments.

Pimoroni’s Tiny 2040 is an RP2040 based board that can fit on the end of your finger.
Given the name “Tiny,” we see that a few sacrifices were made to reduce the board’s size. There are now only 12 GPIO pins, four ADC channels and a button for basic input and selecting the boot option. The Tiny 2040 also shares the top spot for storage capacity with SparkFun’s Thing Plus; both have 16MB of flash storage available.
Currently priced at £8.40, around $12, Tiny 2040 is coming soon on Pimoroni’s website, and we can’t wait to take a look.

Best portable projector Buying Guide: Welcome to What Hi-Fi?’s round-up of the best portable projectors you can buy in 2021.
Projectors are typically neither convenient nor cheap. To get the most out of the best projectors you need to paint entire rooms black, buy yourself a screen, an AVR, a speaker package and possibly even have to fix a chunky mounting bracket onto the ceiling.
This is why portable and mini projectors are a better choice for many. There’s no need to replace your TV. Just pull out your portable when you want to go big and you can even take them around to friends’ houses for movie nights. What’s more, installing a portable projector is no more complicated than finding a flat surface or even a sheet hung in the garden and pointing the thing at it (though a dedicated screen is so much better).
A few years ago, these mini projectors were still hard to recommend despite their convenience. ‘Pico’ projectors had dim light sources that couldn’t do justice to colours or contrast, even in a darkened room.
Today’s portable projectors benefit from improvements to LED and laser light tech. And that means a bigger, brighter picture and no more worrying about having to replace the lamp after a year or so. Traditional halogen projector lamps tend to last 2000-3000 hours. LEDs last tens of thousands.
There’s no magic brand-new tech in the lower-end of the portable world, of course. If a projector fits in the palm of your hand, it will not be particularly bright nor kick out top notch detail. No micro projector works well during the day with the windows open either.
This is one reason our best portable projector round-up includes almost all flavours in this category. There’s a pick so small you could fit it in some large coat pockets. It is great for camping, travelling or for entertaining the kids without putting a TV in their room.
The newer “lunchbox” style projector is a better fit for many, though. They offer a decent compromise of portability and performance, and will likely have the better software extras, as these are real lifestyle tech buys.
Right at the top of the tree are projectors that blur the divide between normal and portable designs. They are only slightly smaller than some normal home projectors but have built-in speakers and other convenience features such as short-throw lenses. These mean the projector does not have to be as far from the screen to create a large, cinematic image, and they can be stowed away in the cupboard again once you’re done with your viewing.
Got all that? If that sounds like the kind of convenience and entertainment you’re looking for, then read on for our best mini projectors of 2021.

1. LG CineBeam HU80KSW
This all-in-one, do-it-all portable projector does it all well.
It’s not what you’d call ‘mini’ but the LG CineBeam has an integrated handle for easy carrying and is small enough to be easily hidden away in a cupboard when not in use.
That’s especially impressive when you consider it’s more or less an entire home cinema system: a 4K HDR picture, stereo sound, an array of smart sources, all in a unit you can carry like a holdall and set up wherever and whenever you might choose. Even the power cable is wound up inside the base, so there is really nothing you have to plug in if you don’t want to.
That’s the great beauty of the CineBeam: its versatility and intuitive simplicity. As long as you have a clean wall or ceiling upon which to throw a picture, you can have it up and running in a matter of minutes each time you use it.
Picture performance is strong: impressively crisp and detailed, with decent depth and natural hues. It is bright enough without being garish, vibrant enough to combat leaked sunlight. And it sounds surprisingly good by the standards of integrated speakers, too.
The only downside is the price, but if you want the best, you’re going to have to pay for it. Besides, you’ll find lots of more affordable options below.

2. Asus F1
Projects a cinematic image in dark rooms.
SPECIFICATIONS
Resolution: 1920 x 1080 | Type: DLP | Brightness: 1200 lumens | Throw ratio: 0.8:1 | Focus: Motorised AF | Zoom: Digital | Keystone correction: +/- 30 degrees | Dimensions: 25 x 75 x 21cm | Weight: 1.8Kg
Reasons to Buy
Decent DLP image
Solid light output
Engaging picture
Reasons to Avoid
No battery
Not the most portable design
The Asus F1 stretches the limits of what we might call a “portable projector”. It does not have a battery and you’ll need a rucksack to take it over to a friend’s house, but it is a very handy projector to take between rooms in your own home.
It weighs just 1.8kg, similar to some laptops, and has a short throw lens. This means it doesn’t need to sit as far from a wall or projector screen to produce a large image. A 1.4m distance gets you 80-inch movies.
It’s also less likely to get damaged when moved about as it uses an LED light array rather than a traditional lamp.
At this size you get much closer to the image quality of a traditional home projector. Its resolution is Full HD, 1920 x 1080 pixels, and the 1200 lumen brightness doesn’t need anything like the light-blocking preparation of a smaller model.
If you want to use a projector in the day time, the significantly brighter Epson EF100 is a better bet. But with the Asus F1 you get a much more cinematic image in a dark room. Colours have real DLP punch and the black level is more than respectable.
We’re not in the same class as JVC’s D-ILA range here, of course, but if you can project onto a grey wall or a white screen with black border, you’re looking at very enjoyable home cinema experience.
Unlike many more traditional projectors, the Asus F1 does not have lens shift or optical lens zoom, just digital zoom and keystone correction. Both limit picture quality so it’s a good idea to take out a tape measure to check it will suit your living room. You need some patience for the menu system too, as it can be very slow to respond.

3. Nebula Mars 2
A battery-powered, truly portable package that’s fun to use.
SPECIFICATIONS
Resolution: 1280 x 720 | Brightness: 300 lumens | Throw ratio: 1.2:1 | Focus: Motorised AF | Zoom: No | Keystone correction: Auto +/-40 degrees | Dimensions: 18 x 12 x 14cm | Weight: 1.8Kg
Reasons to Avoid
Not Full HD
Basic colour reproduction
The Nebula Mars 2 sits in a portable projector sweet spot. It is far from palm-sized, but has a synthetic leather carry strap and a shape similar to the Bang & Olufsen BeoLit 15 “lunchbox” wireless speaker. It’s cute.
This is easily the most fun portable projector in this group too. It has a battery that lasts up to four hours and Android rather than a basic menu system. The front-end is customised for use with the supplied remote, and has a dedicated app store rather than Google Play. But you can still download Netflix, BBC iPlayer and countless other apps to run direct from the Mars 2.
That includes games, but don’t get your hopes up. Most don’t run perfectly, although you can pair your phone and use its touchscreen like a laptop trackpad.
Image quality is respectable too. In a room with closed curtains and no lights switched on, the Mars 2 can produce a watchable image on a 100-inch screen. The projector dims significantly on battery power, but head to the settings menu and you can turn this off. It will simply last closer to two hours than the claimed four.
There’s no worrying about focus either as it has motorised autofocus. Sharpness is less than perfect and there’s some disparity to the sharpness across the image, but you’ll only notice if you look carefully. Its 720p resolution offers far better image detail than a basic 480p model and is a huge upgrade for gaming in particular. And you don’t need to look close to notice that.
The bad parts? Colour reproduction is not particularly good. It lacks finesse and vibrancy, and only minor image controls are available. And while larger than some, the Nebula Mars 2 still needs a partially light-controlled room to produce sufficient image contrast.

4. Viewsonic M1+
A tiny projector with built-in Harman Kardon speakers.
SPECIFICATIONS
Resolution: 854 x 480 | Brightness: 300 lumens | Throw ratio: 1.2:1 | Focus: Manual dial | Zoom: No | Keystone correction: Veryical +/-40 degrees | Dimensions: 14.5 x 12.6 x 4cm
Reasons to Buy
Reasonable image in dim light
Speaker goes surprisingly loud
Reasons to Avoid
Low resolution and brightness
Poor focus control
Mini projectors don’t get much more convenient than the Viewsonic M1+. It’s tiny, and only weighs as much as four phones stacked in a pile. And it does come with wi-fi, a MicroSD card slot, plus USB Type-A and USB Type-C connectors.
The stand makes projecting an image from slanted surface, or onto angled walls, a cinch. Its speaker is the real surprise, though. While it sounds harsh and brash at maximum volume, the dual Harman Kardon speakers deliver enough volume for a movie night if you keep things sensible. The sound may only be that of mediocre budget bluetooth speaker, but it’s much better than that of most pint-size projectors.
Image quality is mixed, and not up to the traditional standards of TVs and projectors. That’s hardly surprising as resolution is very low at 854×480 pixels. Text looks terrible, but we are pleasantly surprised by how invisible the pixel structure is even when projecting at 100 inches. Faces look smooth rather than blocky, although naturally there’s limited fine detail. This is a DVD-quality projector, not an HD one.
The Viewsonic M1+’s focusing is fiddly too. It has a flimsy wheel, and the M1+ tends to change focus slightly as soon as your take your finger off the control. Getting a perfectly in-focus picture requires some finger gymnastics.
And, no surprise here, the Viewsonic M1+ needs a fairly dark room to achieve an acceptable image. No-one is likely to be bowled over by this projector. But it is compact, relatively affordable, sounds reasonable, has a three-hour battery life and does a fair job displaying SD-quality movies. If that’s all you require, it does the job.
