Panasonic Soundslayer soundbar review: Does it truly ‘slay’ gaming audio?

(Pocket-lint) – If you want to make a worthwhile difference to the sound of your TV, you’re spoilt for choice where soundbars at the lower end of the budget scale are concerned. Equally, if you feel your games console experience requires a sonic rocket, there are numerous LED-happy gaming soundbars ready to do a job for you.

But what if you want both – and you want something small and discreet enough to cause minimal disruption to your viewing and/or gaming environment(s) at the same time? Your shortlist has suddenly become quite a lot shorter.

You can now add the Panasonic SC-HTB01 – or Soundslayer, as it’s also rather excitably known – to your shortlist, though. It may be physically small, but it’s big on performance.

Design

  • Ports: 1x HDMI input, 1x HDMI output, 1x optical input
  • Dimensions: 52 x 431 x 132mm / Weight: 1.8kg
  • Finish: Matte Black only

Obviously, the big news is how small the Panasonic is. It’s perfectly proportioned to sit discreetly underneath your TV or games monitor, and at this weight it’s hardly a burden to move it from one position to another. But it’s still big enough to be fitted with reasonably sized speaker drivers. 

‘Design’ doesn’t really seem to be something that’s happened to the SC-HTB01 – rather, its drivers and accompanying electronics have been put into a housing which has then been mostly covered with acoustic cloth. Its plastics feel ordinary. It’s basically not much to look at – although it’s easy to imagine Panasonic thinking that’s entirely the point.

‘Bland’ isn’t the same as ‘badly made’ though – this, after all, is Panasonic we’re talking about. The Soundslayer may not be visually stimulating, but it’s properly screwed together and feels made to last.

Features

  • Decoding: Dolby Atmos & DTS:X supported
  • Modes: Game, Standard, Music, Cinema
  • 4K HDR passthrough supported

There is a brief suite of physical connections on the rear of the soundbar. A couple of HDMI sockets – one input, one ARC-enabled output – a digital optical input, and a USB socket (for updates only).

Panasonic

Via HDMI, the Soundslayer can handle 4K HDR content as well as multi-channel audio up to a hefty 24bit/192kHz standard – so Dolby Atmos and/or DTS:X soundtracks present no problems. Wirelessly connectivity is handled by Bluetooth 2.1 – hands up who remembers when that was the cutting edge of wireless streaming technology?  

The SC-HTB01’s equaliser (EQ) presets let you know where it thinks it belongs. Presets for ‘music’, ‘cinema’ and ‘standard’ attest to its flexibility – but within the ‘game’ preset there are sub-settings for ‘RPG’, ‘FPS’ and ‘enhanced voices’ (which is excellent when listening at very low volume levels). 

Interface

  • Included remote control

It’s not a problem, in and of itself, that the Panasonic has no voice assistant or control app. It’s not a problem that everything, from subwoofer level and overall volume level to EQ preset and Bluetooth pairing, is taken care of by a full-function remote control handset. 

Panasonic

No, the problem is that the remote control seems to have been selected on the basis that there were no more affordable options available. It’s small, hard, thin, unpleasant to hold, and very nearly as unpleasant to use.

But at least there is one included, we suppose. 

Sound quality

  • Drivers: 2x 4cm full-range, 2x 1.4cm tweeters, 1x 8cm woofer, 1x passive radiators
  • Configuration: ‘2.1’ channel output
  • 80W of Class D power

Behind that mild-mannered exterior, two 40mm full-range drivers and two 14mm tweeters face forwards. On the top of the ‘bar there’s an upward-firing 80mm bass driver, alongside passive low-frequency radiators. Panasonic is striving for a ‘2.1’ channel effect with this five-driver layout, and has fitted the SC-HTB01 with 80 Watts of power with which to make it happen.

Panasonic

There’s also a bass reflex slot at the front of the cabinet, just in case that passive radiator doesn’t quite pull its weight. Naturally, this upward-firing configuration means the Panasonic shouldn’t be positioned with surfaces directly above it.

So how does all that come across? Well, if you’ve been using the audio system integrated into your TV or your monitor up until now, the SC-HTB01 will thrill you with the scale and drive of its sound.

The combination of judicious speaker driver placement and careful EQs means the Panasonic sounds bigger – and in every direction – than seems likely from a soundbar this tiny. There’s no mistaking its presentation for that of a dedicated Dolby Atmos soundbar, naturally, but the Soundslayer’s soundstage is taller, deeper and (especially) wider than it would seem to have any right to be.

At the top of the frequency range it carries plenty of detail, and gives treble sound lots of substance to go along with their considerable bite. Further down, the midrange is nicely shaped and projects forward well – even without the intervention of the EQ presets.

It’s down at the bottom of the frequency range, though, that the Panasonic both triumphs and fails. This isn’t the first soundbar to have mistaken ‘overconfident bass’ for ‘excitement’ – and, to be absolutely fair, the SC-HTB01 controls the low-end stuff pretty well. It certainly doesn’t drone and doesn’t blossom into the midrange, either. But it definitely overplays its hand where bass is concerned – ‘punchy’ is one thing, but being repeatedly punched while trying to watch TV or concentrate on a game is quite another.

Panasonic

The big, bassy emphasis doesn’t help the Panasonic’s overall detail retrieval, which is a pity. It’s possible to independently adjust the ‘subwoofer’ level using the remote control, but the effect is not so much to reduce the soundbar’s outright wallop as to rob it of its dynamism.

That’s unfortunate, because the Soundslayer ordinarily has more than enough dynamism to maximise any game soundtrack you care to mention. It can put a huge amount of distance between ‘stealth’ and ‘assault’, which adds a lot to the gaming experience.

It works well for movies, too – when the soundtrack demands a shift from ‘quiet and contemplative’ to ‘massive attack’, the Panasonic relishes the opportunity. It’s so much more accomplished than the sound of your average TV, and consequently far more involving.

The temptation, naturally, is to go all-in on the volume – but that would be a mistake. The Soundslayer’s tonal balance, which at moderate volume levels is pretty well judged, takes a definite turn for the ‘hard and unforgiving’ if you decide to press on. Treble sounds get edgy and thin, and the bass stops punching and starts slapping. Stick to reasonable levels, in other words – it’s not only your neighbours who will thank you.

Verdict

Keep its limitations in mind and there’s lots to like about the Panasonic SC-HTB01. It may not quite be the ‘soundslayer’ it purports to be, but it’s a convenient and capable way of giving your games and movies a bit more sonic oomph. As long as you don’t get carried away with volume, anyhow.

Slightly bigger than the Panasonic, slightly less expensive too, but designed to do much the same job. It is similarly unruly when the volume get big, too, but overall is probably a marginally better bet.

Our Verdict

KEF’s first noise-cancelling wireless earbuds make a positive impression, even if they fall short of being best-in-class

For

  • Refined, mature balance
  • Weighty bass
  • Good battery life

Against

  • Beaten for dynamics and expression
  • Call quality could be better

KEF has dabbled in the headphone market since 2013, experimenting with both over-ear and in-ear models over the years, however it’s fair to say the hi-fi giant hasn’t set the headphone market alight. But could all that be about to change with the ambitious Mu3?

The Mu3 are KEF’s first-ever wireless noise-cancelling earbuds and, in terms of price, slot somewhere in between the big-hitting Sony WF-1000XM3 and the Bose QuietComfort Earbuds.

If you haven’t heard of Ross Lovegrove before you buy the KEFs, you will have by the time you have unboxed them. His name is emblazoned on the packaging, the instructions and even on the inside of the Mu3 case.

Lovegrove has helped design several KEF products in the past, most notably the KEF Muon – an impressive-looking pair of limited-edition, aluminium, floorstanding speakers that cost an impressive £140,000 ($198,000) per pair. He also played a major part in designing the Award-winning KEF Muo wireless speaker, and now he has turned his hand to a pair of true wireless earbuds.

Type True wireless in-ears

Bluetooth Yes

Noise-cancelling Yes

Battery life 9 hours (+15 hours from case)

Weight 5.8g (each)

From the moment you take the headphones from their packaging, you can see Lovegrove’s involvement. The case looks like a large blob of liquid metal but has a nice subtle shape. It feels robust, too, while the smooth glossy plastic helps to give a more premium first impression. It’s a similar story when you open the case up. The Lovegrove name on the inside might be one nod to the designer too many, but the sheen from the small silver earbuds also gets your attention.

The buds look and feel in keeping with the case, from the smooth glossy exteriors to the KEF logo imprinted on the surface of each bud. They’re surprisingly small, which makes them a little slippery when placed between finger and thumb, but getting them in place with a good seal isn’t too tricky. Pick your eartips (there are four different sizes to choose from), drop them in and twist the buds slightly to lock them into place.

Comfort

Provided you achieve a good seal, the level of passive noise isolation on offer is decent. While finding them pretty comfortable for a brief stroll, we are a little less convinced of their comfort during longer listening sessions. The Sony WF-1000XM3 are a slightly bulkier design but feel much less intrusive, as do the Bose QuietComfort Earbuds.

The first time you open the case, the headphones automatically start the pairing process. Once partnered to your headphones, they connect almost as soon as the lid is lifted.

On the outer surface of each earbud, you’ll find a small KEF logo that sits on a circular control button. There are no touch controls here, but the physical ones work perfectly well – and also means you won’t accidentally hit play or skip a track when putting them in place.

On the left earbud, a long press turns the volume down, while a short press switches the noise-cancelling on or off and engages the ambient mode (which lets you hear your surroundings without having to take the buds out of your ears). On the right earbud, a short press answers calls and plays or pauses music and a long press increases volume. Pressing twice stops your phone call or skips forward a track.

Battery life comes in at an excellent nine hours, with the case giving a claimed extra 15 hours of additional juice to keep the buds going. By comparison, the class-leading Sony WF-1000XM3 offer around six hours. If you’re caught short, a quick five-minute blast from the charging case (which uses USB-C) should give you an hour of playtime.

There’s a small LED on the case which blinks when the battery is low, but it’s not that obvious against the glossy plastics and it also doesn’t give any real indication of just how much charge is left. We were caught out when our buds needed charging, only to find the case was also running on empty.

Unlike many wireless earbuds around this price, there’s no app to accompany the KEF Mu3. This means there’s no EQ adjustment for you to play with, but that’s only an issue if you aren’t happy with the balance of the KEFs. And we can’t see why you wouldn’t be.

Sound

(Image credit: KEF)

The KEFs produce a wonderfully balanced sound that’s smooth and refined. They’re quite effortless in their delivery and present the music in a mature and sophisticated fashion, making them easy to listen to over prolonged periods. You can push them to the limits of their battery life and emerge on the other side not feeling drained or tired of their sound.

We play Shout by Tears For Fears and notice fullness and finesse to the percussion, plus a good amount of space around the instruments. There is no hint of harshness as chimes cut through the song’s rich vocal and solid, yet relatively mild-mannered bass. However, the Sony WF-1000XM3 deliver the song with a greater sense of sparkle, proving capable of finding an extra gear when it comes to drama and drive.

Switch to Hayden Thorpe’s Diviner and the smooth, soulful delivery of the track plays to the KEF’s strengths. His vocal is rich and full-bodied with a good sense of expression, while the individual strokes of the piano keys come across well. Again, the Sonys take this level of dynamics and expression up a notch, forming a tighter emotional bond with the listener.

Moving on to Massive Attack’s Angel, the KEFs cope well with the track’s powerful and relentless bassline. There’s a richness to each bass pulse and they sound solid, even if rivals can paint them with greater texture.

The Mu3 do a good job of keeping outside interference to a minimum. Their noise-cancelling tech doesn’t produce such stark results as the Bose QuietComfort Earbuds, but it’s effective and, anyway, not everyone is comfortable with the vacuum-like feeling that more aggressive noise-cancelling technology can have.

The call quality could be better, though. While the best pairs of true wireless earbuds lend your voice a more natural-sounding quality, the KEFs have a slightly coarse edge and introduce more compression.

Verdict

KEF has put its head above the parapet and produced a pair of true wireless earbuds that can be considered worthy rivals to the Apple AirPods Pro. However, we have some reservations about the call quality, and while nothing about the performance stands out as being a negative, the Mu3 can’t quite match the sonic ability of the class-leading rivals at this level from the likes of Bose and Sony.

However, if you’re a fan of the KEF brand – or Ross Lovegrove in particular – and have the funds at your disposal, it’s well worth giving them a chance.
