Bluesound Pulse M review: a wireless speaker that fails to justify its substantial price tag, sonically speaking

Bluesound Pulse M: two-minute review

The Bluesound Pulse M is a mid-market multi-room speaker that promises wide, immersive sound. It’s compatible with both lossless streaming and hi-res audio over a wired connection, and is clearly aimed at audiophiles who are looking for a compact yet versatile speaker. On top of this, its angled tweeters are billed as providing a broader stereo effect than many single-unit setups are capable of.

The Bluesound Pulse M’s audio is impressively detailed, as you’d expect from a speaker capable of lossless streaming. I was impressed by how Diamonds on the Soles of Her Shoes by Paul Simon managed to sound both warm and crisp, with his voice rising above the mix and that tight, noodly guitarwork cutting right through. And its stereo effect is genuinely impressive – while you won’t hear two distinct channels for left and right per se, there’s still a separation to its sound that feels broader than a single speaker should be able to deliver.

Unfortunately, this is somewhat undermined by how unbalanced the audio can be. Like a lot of speakers in recent years, the Pulse M bets big on bass, which would normally be a pretty safe bet for a fan of sub like myself. However, in the process it neglects other frequencies, with mids in particular suffering compared to many of the best wireless speakers. With its sub and kicks, a slice of warm tech like Burst by Kiasmos should really shine on a bassier speaker, but instead that dusty arpeggiated synth and lush strings came off as slightly foggy here.

It is possible to rectify this using some of the speaker’s sound profiles. Personally, I found Front Row, Bluesound’s enhanced profile, to be a bit of a damp squib – it absolutely has an impact on the sound, giving it a bit more urgency, but that comes at the expense of a compressed feeling overall. Instead, I found using the BluOS app’s settings to boost treble and duck the bass achieved better results – although I did find myself wishing it had proper EQ settings to give me even more direct control over the sound.

When it comes to setting up and controlling the Pulse M, Bluesound’s BluOS app is easy enough to use, although it has some odd issues here and there. When setting up the speaker, multiple steps would fail, only to immediately succeed when I retried. And these glitches extend to its Alexa voice control skill as well. I found I was able to pause, play and skip music, but every time I asked my Echo Dot to select a specific track the Pulse M remained obstinately silent – so if voice control is your thing, you might be better off with one of the best smart speakers instead.

Design is probably the area where the Pulse M shines most. It’s well built, feeling sturdy without being overly heavy or bulky, while its white matte finish feels suitably premium to the touch. A built-in proximity sensor only lights up the buttons when you wave your hand near, which feels appropriately sci-fi. However, I’d personally prefer the touch-sensitive buttons to have some haptic feedback; offering that immediate feedback when pressed would make it much more obvious when the speaker has registered your input.

All in all, the Bluesound Pulse M is a quality mid-range speaker that’s able to produce detailed, hi-res audio. Ultimately though, it lacks the nuance I’d expect from a speaker that costs $399 / £399 – powerful bass shouldn’t come at the expense of lush, expressive mids. Coupled with the fact that similarly priced speakers offer more – the JBL Authentics 200 offers fuller, more rounded sound for $349.95 / £299, while the spatial-audio-equipped Sonos Era 300 costs just $449 / £449 / AU$749 – this makes the Pulse M harder to recommend.

Bluesound Pulse M review: price and availability

• Released October 26, 2022
• Costs $399 / £399 / AU$899

Launched on October 26, 2022, the Bluesound Pulse M is available to buy now. It retails for $399 / £399 / around AU$899, which puts it firmly in mid-market territory – it costs a fair way north of the Sonos Era 100 at $249 / £249 / AU$399 but doesn’t quite cost as much as its premium cousin the Sonos Era 300 at $449 / £449 / AU$749.

In return for your spend, you’ll get a compact speaker with 80W of combined amplification, a single woofer and two angled tweeters. There’s not a huge variety in terms of options. It comes in just two colorways – black or white – but that’s pretty common with more premium speakers.

Bluesound Pulse M review: features

• Great range of connectivity options
• Occasional app gremlins
• Limited EQ options

The Bluesound Pulse M rocks a decent number of features for a wireless, multi-room speaker, without necessarily ripping up the rulebook. It offers a combined 80W total amplification power, with 50W going to its upfiring 5.25-inch woofer and 15W to each of its 0.75-inch tweeters. The latter two are offset at 45 degrees from each other to give what Bluesound describes as an ‘immersive’ soundstage. Combined with an inbuilt acoustic reflector, this helps to radiate higher-frequency sounds in a 360-degree pattern, reducing the impression that the sound all emerges from a single point in space.

Getting started with the Pulse M is relatively straightforward. Once you’ve downloaded the BluOS app you just need to connect your mobile device to the speaker’s hotspot so it can piggyback on it to join your local Wi-Fi network. This process is pretty simple, but that doesn’t mean it’s completely smooth sailing – at multiple points I would find the connection process would time out, only to connect instantly when I retried. This did add a bit of friction to the process, particularly given that the Pulse M seemed to need setting up afresh every time it was unplugged.

Once the BluOS app is connected, it enables you to connect to the speaker via Bluetooth or AirPlay 2, as well as connecting specific apps like Spotify, Tidal and Amazon Music directly to the Pulse M. The app also allows you to pair it with other Bluesound speakers to form a multi-room setup, or pair two Pulse Ms with the Pulse Soundbar+ or PowerNode to create an effective surround sound setup for your home cinema.

The BluOS app is also where you’ll find options to tweak the Pulse M’s sound profiles. On top of its default profile, it also offers Front Row, a setting that, according to Bluesound, enhances “richness in the lower frequencies (<60Hz)” and “openness and expansiveness in the higher frequencies (>5kHz)”. It also offers access to the Tone Control settings, although these are unfortunately pretty limited: plenty of budget price Bluetooth speakers like the Tribit Xsound Plus 2 offer full nine-band EQ, whereas this speaker only allows you to boost or reduce treble or bass by 6dB either way. The BluOS app also offers ‘Replay-gain’, essentially an auto-gain adjustment that tweaks different tracks or albums to make sure they play back at similar volumes. I can’t say this is a problem I have very often these days, given that many streaming services standardize recordings to be at the same volume, but it’s nice to have I guess.

Naturally, the BluOS app isn’t the only way to control the Pulse M. If you want to control it as part of your smart home network, you can connect it to an Amazon Echo speaker using the BluOS Voice Control skill in the Alexa app. Unfortunately though, the skill seems to have a few holes here and there. Try as I might, I couldn’t get Alexa to select specific songs and artists – it would happily chirp that music was playing through my named speaker and then nothing would start. When I manually selected music though, Alexa was at least able to pause and play, as well as adjust the volume and skip backwards and forwards. So it’s a mixed bag: you’ll still have to reach for your phone a fair amount.

Should you prefer using your own digits to digital controls, the Bluesound Pulse M has a range of touch-sensitive controls on top of the speaker itself. These are invisible most of the time, but wave a hand over them and they’ll light up – you can then tap them to play and pause, skip forwards and backwards, set the volume, and pick one of five audio presets you’ve assigned in the app.

Bluesound Pulse M review: sound quality

• Over-liberal with its bass
• Front Row audio profile lacks finesse
• Genuinely impressive breadth to its soundstage

When you actually fire up the Bluesound Pulse M, the first thing you’ll likely notice is its bass. In fact, that’s probably the only thing you’ll notice. When listening to Black Eye by Allie X, I was immediately impressed with how punchy the kick sounded and how warm the low subby end of the bass sounded – but the mids sounded set quite far back in comparison. I tried switching things up to Rosewood by Bonobo, a track that very much shines on a warmer speaker and, once again, it felt like the bass overshadowed the rest of the mix, which is pretty disappointing.

Comparing it to the Sonos Era 100, it became much easier for me to diagnose the problem. In our original Sonos Era 100 review, we criticised it for its over-emphasis on bass and yet it comes across as far better integrated and more coherent. In contrast, the Pulse M pulls way too many punches when it comes to its mids. Weighing up the two while listening to Young Blood by The Naked & Famous, there’s a real slam and thud to the bass kicks and snares to the Pulse M but, like the weightlifter who overlooks their core to focus on their arms and legs, all this flexing only serves to draw more attention to its soggy middle in comparison to its trimmer rival.

That’s not to say it completely lacks all precision. In sparser mixes, things feel like they have much more room for expression. Listening to the sparser ballad-y composition of Rains again by Solji, I was impressed with how polished and detailed her voice sounds, while the drum beats and piano are granted plenty of room to breathe – when the bass isn’t hogging all the limelight, other elements are given their chance to shine.

Given the default sound is a bit of a mixed bag, you might expect Front Row, BluOS’s inbuilt frequency tweaking, to step in and save the day. In practice, it’s a bit of a blunt tool, akin to using a pocket knife for micro-surgery. Some tracks definitely shine more with it on – originally White Dress by Lana Del Rey sounded a bit demure and lacklustre to me but Front Row boosted the breathy edge to her voice and made that light cymbal work a bit more crisp. Conversely, it brought the beat and vocals in Baby It’s You by London Grammar forward a lot but at the expense of making things sound a bit too compressed.

In my personal experience, you’ll get better results getting your hands dirty and tweaking the Tone Control settings according to your own tastes. Upping the treble by 6dB on London Grammar’s track gave its hats and Hannah Reid’s honeyed vocal that little more immediacy, while dropping the bass just a fraction by 6dB tamed the Pulse M’s worst impulses. Ultimately, this setting felt much more balanced for me and I ended up using it as standard pretty much from there on out.

One place I will commend the Pulse M however is for its soundstage. Thanks to those angled, stereo tweeters, this speaker offers a much wider sound than the narrow point of origin that many single speakers are capable of. Playing Manchild by Eels, there was genuinely an impressive sense of separation between the vocal and the guitar in the left and right channels, especially the further back I was sat in the room. While I’m not convinced I would describe this as true stereo, as Bluesound has, there’s no doubt it feels immersive and broad – although it’s not quite as impressive as the Dolby Atmos a speaker like the Sonos Era 300 offers.

Bluesound Pulse M review: design

• Gorgeous, refined design
• Solidly built but not bulky
• Controls could offer more feedback

For the most part, I’m a big fan of the Bluesound Pulse M’s design. The brand has nailed the nexus of minimal and premium that’s absolutely appropriate with a speaker at this price point.

Essentially a cylindrical oval shape, it gives off slight Sonos Move 2 vibes, while still being distinct enough to feel like its own beast. It comes in both black or white colorways; for me the latter has the definite edge here, feeling much cleaner and more futuristic. Its plastic body has a pleasing matte finish, while the fabric-covered grille has a curved bottom edge giving the whole thing a nice aesthetic balance. When it comes to the pure look of the device, I – unusually – have nothing negative to say.

Again, in build quality, the Pulse M occupies a Goldilocks zone of both solid without being overly bulky. The absence of a battery helps here, of course: moving it from room to room requires considerably less exertion than something like the Move 2. While it’s close in size to the Sonos Era 300, it’s significantly lighter, weighing in at 2.54kg compared to the Era 300’s 4.47kg. While you’re not likely to be repositioning it very often, it’ll definitely be less cumbersome when you do.

One slight niggle centers around the touch-sensitive controls on top of the device. Given they aren’t physical buttons, I’d personally have preferred it if they’d included some haptic, or at least aural, feedback to confirm a successful finger press – I wasn’t always clear when it had actually registered a finger-press on the volume bar, meaning I’d often stab at it several times to be sure. But more of an issue for me is the lack of labelling: minimal buttons sure look cool until you’re trying to work out what half of them do, at which point you start to appreciate why almost all speakers follow certain conventions, like pluses and minus for volume or numbers for presets.

All things considered though, this feels more like splitting gossamer than splitting hairs – the overall style and build of the Bluesound Pulse M is aesthetically pleasing, and creates a decent impact in any room it’s situated in.

Bluesound Pulse M review: value

• Looks and build match its premium price
• Sound can’t compete with similarly priced speakers
• You’ll likely get better value for your spend elsewhere

Weighing up how the Bluesound Pulse M compares in terms of value is a tough undertaking. On the one hand, it looks stunning, works as part of a multi-room setup and can stream true lossless audio. On the other, its bass out-of-the-box is seriously overblown, its app can be periodically frustrating and it’s a bit lacking when it comes to audio optimisation features.

Those kinds of compromises would mostly be fine if the Pulse M was cheaper or the competition wasn’t so good at this price range. But this is not an affordable wireless speaker: at an MSRP of $399 / £399 / around AUS899, it’s reasonable for you to expect more than you’re getting here. For that kind of money, I want a speaker to sound great right out of the box, ideally with algorithms that optimise the sound depending on the surroundings. And the Pulse M just cannot clear that bar, which feels like a missed opportunity.

So while this is a very capable speaker in a lot of ways, it’s still not enough to quite justify the high price tag: there are simply too many speakers out there that will give you better sound for your spend. For example, the JBL Authentics 200 is available for $349.95 / £299 / AU$299 and offers both the full bass and crisp treble of the Bluesound, while providing full, convincing mids. Alternatively, the Sonos Era 300 doesn’t retail for much more, at $449 / £449 / AU$749, and it rocks both full sound as well as that awesome spatial audio effect.

Should I buy the Bluesound Pulse M?

Bluesound Pulse M review: how I tested

• Tested for two weeks
• Used in a range of rooms and settings
• Played a wide range of music over Wi-Fi, Bluetooth and wired connections

I spent many hours testing the Bluesound Pulse M over the course of several weeks. Not only did I try it out in multiple different sized spaces, I also compared it to the Sonos Era 100 and hooked it up to a variety of devices, including my iPhone 16 Pro over AirPlay 2 and the Fiio M11S hi-res music player via analog stereo 3.5mm input.

In terms of music, I used our curated TechRadar testing playlist, as well as a wide array of tracks from my personal library. This allowed me to try out how the speaker handled everything from deep pulsing bass to delicate vocals. I also used a variety of different quality sources, whether that was Spotify’s standard tier, Apple’s lossless tier or Tidal’s hi-res tier.

I’ve been testing audio kit like headphones and speakers for many years now. I’ve also spent decades making music in my free time, which has given me a lot of insight into analyzing the frequencies of music, composition and soundstage.
