General
Unique Melody needs no introduction. Most of us know them for their bone conduction IEMs, from the MEST line all the way up to the Mason flagships. So when UM steps into the TWS space, the expectation is quite clear. It has to sound good first.
The UXUE is priced at $299. It packs a triple driver hybrid setup in each shell: a 10mm carbon nanotube dynamic driver, a balanced armature, and UM's signature silver-palladium bone conduction driver. Running the show is a Qualcomm QCC5144 chipset with Bluetooth 5.2, aptX Lossless and 24-bit/96kHz support. That is a lot of hardware for a TWS at this price.
Most TWS in this bracket are built around a single dynamic driver and a long list of lifestyle features. The UXUE goes the other way. UM spent the budget on the acoustics and kept the extras to a minimum. Whether that works for you depends on what you want from a pair of wireless earbuds. For me, I was curious whether that bone conduction magic I enjoy on their wired IEMs could survive the jump to Bluetooth. I have spent a good few weeks with the UXUE as my daily driver, at home, at work and on the go, so this review is based on real world usage rather than a quick weekend impression.
Packaging & Accessories
Packaging is simple and straightforward. Nothing fancy here, and honestly that's fine for a TWS. You open it once and move on.
Inside the box:
Two sets of tips, vented and non-vented, is a nice touch. You get to choose between a bit more air or a proper seal straight out of the box. The liquid silicone feels soft and pleasant on the skin too. A small pouch would have been nice for the asking price, but that's purely me nitpicking.
Build & Comfort
The shells come in a matte black finish with gold accents. It feels smooth to the touch and the earbuds are light. It doesn't scream premium, but it doesn't feel cheap either. The charging case is on the chunkier side, so it sits better in a bag than in a tight jeans pocket.
Fit is where I had a slight issue. The stock tips sit quite shallow, and I struggled to get a consistent seal with them. Once the seal is off, the bass thins out and the upper mids get a bit more forward. So naturally, I went tip rolling. With third party eartips, the fit improved a lot and the UXUE stays put in my ears for hours without any discomfort. A slightly deeper insertion also helps the bone conduction driver do its job, since that sense of density depends on proper contact.
But here comes the bummer. With the third party tips on, the earbuds will not fit into the charging case. The case is simply too shallow for them. So every time I want to charge, I have to swap the tips back or take them off. It's a small thing, but it gets annoying quickly in daily use, especially when you're on the move and just want to drop them in. Hopefully UM can make the case slightly deeper in the next iteration.
Gears Used for This Review
Xiaomi 17 Ultra
Unique Melody UXUE
Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone's ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far.
Features
Noise Control
There is no ANC on the UXUE. Instead you get three modes: Hi-Fi, Ambient and Hearing.
Hi-Fi mode is the one for actual music listening. It relies purely on passive isolation, so a good seal matters.
Ambient mode lets outside sound in so you stay aware of your surroundings.
Hearing mode pushes voices forward, more for conversations than for music.
Modes can be cycled by touching the left earbud, or through the app.
With a good seal, passive isolation is decent enough for the office and quieter commutes. On a noisy bus or a flight, you will feel the absence of ANC.
Amplification Modes
The UXUE offers a choice between Class AB and Class D amplification.
Class AB is the default and the one I used throughout the review. It sounds smoother and more natural to my ears.
Class D trades a bit of that for better efficiency and longer runtime.
Do note that switching is done by flashing firmware, not on the fly. Not the most convenient, but it's a rare feature on a TWS and a very audiophile oriented touch.
Battery
UM rates it at around 5 hours (Class AB) and 6 hours (Class D) on the earbuds, with the case bringing it to roughly 10 and 12 hours respectively.
In my usage, it's a little short. A long session or a couple of commutes and it's back in the case.
I suspect the three driver setup simply draws more power than the usual single dynamic driver TWS. Take the rated numbers with a pinch of salt, especially if you listen loud.
App (UM Smart Sound)
Clean and simple, no ads, no clutter.
Mode switching, gaming mode, touch control customisation, in-ear detection toggle and firmware updates.
A 5-band EQ (32Hz, 125Hz, 500Hz, 2kHz, 8kHz) plus a few presets. Basic, but it does everything alright for small tweaks.
I kept the EQ flat for most of the review. The stock tuning doesn't really need much help once the fit is sorted.
Connectivity
Bluetooth 5.2, aptX Lossless and 24-bit/96kHz playback.
Paired with the Xiaomi 17 Ultra, the connection was rock solid. No random dropouts walking around the house, in the mall or on the go.
Even with the phone in my back pocket and walking a couple of rooms away, the signal held up without stutters.
In-ear detection and touch response are quick and reliable.
IP55 rated for sweat and water resistance.
Sound Impression
The UXUE has been run on my burn-in rig for approximately 30-40 hours before any critical listening, and the treble settled slightly and sounds more refined after that. Overall tonality is balanced with a slight hint of warmth. It doesn't sound like your typical bass heavy consumer TWS at all, and it's tuned for long listening rather than to wow you in the first five minutes.
Bass
Good body and impact, with sub-bass digging in when the track calls for it.
On Daft Punk the rumble is there. Not basshead level, but convincing for a TWS.
Billie Eilish's Bad Guy goes deep enough to carry the track without turning into a boomy mess.
Quick with a natural decay. On Slipknot's Duality the double kicks stay tight and don't smear.
Mid bass punch is clean and controlled, and it doesn't bleed into the mids at all.
Seal matters here. With the stock tips the low end thins out, while third party tips bring back the weight.
Mids
This is where the UM DNA shows.
Vocals are natural and slightly forward, picture the artist as 3-4 steps in front of you rather than shouting into your face.
Female vocals: Faye Wong comes through clean and airy with good texture, never sharp.
Male vocals: Zhao Peng has enough chesty weight to sound full rather than thin.
Na Ying carries good density, with a slight wetness that keeps vocals from sounding dry or clinical.
The bone conduction driver earns its place here to my ears, adding density and layering that most single driver TWS simply can't do.
With the stock tips, the upper mids can get a tad forward on certain tracks. Once the seal is sorted with third party tips, it calms down nicely.
Treble
Smooth and controlled with decent extension.
Cymbals have enough bite without getting splashy.
Detailed enough without being sharp or fatiguing.
Not the airiest top end around, purely nitpicking for a TWS.
Soundstage / Imaging
Wide and open with decent depth, a little out of head for a TWS.
On Hans Zimmer's Why So Serious the layers stay separated and imaging is precise enough to follow the instruments around.
Even on YungBlud's Zombie live recording, the crowd and band don't collapse into a single blob.
To my ears, this is easily one of the best sounding TWS I have heard for the asking price.
Comparison
Unique Melody UXUE vs Hifiman Svanar Wireless
Build & Ergonomics
The Svanar Wireless is big and bulky. The shells stick out quite a bit and the ergonomics just don't work for my ears. I could never get it to sit comfortably for long sessions.
The UXUE is noticeably smaller and lighter. Once I sorted out the tips, it disappears in the ear far better than the Svanar ever did.
Battery life is short on both. Neither will last you a full day of heavy listening, so this one is a draw.
The Svanar does have ANC, which the UXUE lacks. If noise cancelling is a must, that's a point in Hifiman's favour, but honestly, it doesnt work that well on the level of say, Sony’s WF series or Apple’s Air Pod Pro
Sound
Bass: Both have decent body, but the UXUE sounds tighter and cleaner, with no bleed into the mids.
Mids: The UXUE has the edge in layering and density, thanks to the bone conduction driver.
Treble: This is where the Svanar loses me. It can get a bit offensive depending on the track, especially on brighter recordings. The UXUE stays smooth and controlled throughout.
Soundstage: The UXUE feels more open and better layered to my ears.
Verdict: I would personally go for the UXUE. Better fit, a smoother and more refined sound, and none of the treble fatigue I get from the Svanar. Unless ANC is a deal breaker for you, the UXUE is the better choice.
Final Thoughts
The UXUE knows exactly what it wants to be. It's a TWS that puts sound quality above everything else, and it shows. The tuning is balanced and mature, the bass is clean, the vocals carry that UM layering, and the stage is far bigger than what I expect from a pair of wireless earbuds. Signal stability is excellent too, which matters a lot more in daily use than most people think. A TWS that sounds great but keeps cutting out is useless, and the UXUE never gave me that frustration.
It's not without compromises though. The fit with stock tips is not ideal, and the case not accepting third party tips is the biggest bummer for me since that's exactly how I got the best fit and sound out of it. Battery life is a little short, and there's no ANC. But I don't see these as deal breakers, because UM never set out to build a feature packed lifestyle earbud. If you want the strongest ANC and the longest battery, there are other options out there. If you want a wireless IEM that actually sounds like it came from an IEM brand, the UXUE is a very good place to be.
For me, it has found its spot as the grab and go pair when I don't want to deal with cables but still want proper sound. Fix the case depth and stretch the battery a bit, and the next UM TWS could be something really special.
