Sennheiser HDB 630 Review: The Wireless Sound Owners Rate Highest, in a Body They Do Not Love
Quick take
Nine owners point at the same thing: this is the best-sounding wireless headphone they have heard. Four of them get there by direct comparison with Sennheiser's own Momentum 4 and 5, and one describes it as a wireless closed-back HD 650 with more bass and a genuinely useful parametric EQ. The catch is everything you can see and touch. Three owners call the build plasticky, plain or simply not up to the price, and one is trading theirs for a Momentum 5 purely on looks.
Sennheiser HDB 630 is a closed-back wireless headphone with active noise cancelling, wired USB-DAC playback, and deep parametric EQ, aimed at listeners who want a neutral, highly tunable sound in a travel-friendly package.
Neutral, highly tunable wireless ANC sound
Quick Verdict: Is Sennheiser HDB 630 Worth Buying?
The sound-first wireless headphone, rated above Sennheiser's own Momentum line by four owners who have used both. The build, looks and ANC are where the money visibly did not go, so this suits listeners rather than commuters.
Evidence confidence: High.

Pro HDB 630 against the Momentum 4 and 5: where the money goes
Sennheiser HDB 630 gets its strongest positive signal from audiophile-grade sound for a wireless headphone. The points below summarize why buyers keep it on their shortlist.
Like audiophile-grade sound for a wireless headphone 2026-09-01
I had the momentum 4s, they were good but nowhere near audiophile level. HDB630 is really good for a wireless headphone
Like great over bluetooth 2026-08-23
I have M4 and HDB630. I think you should get 630’s. Sound quality is very good for Bluetooth and usbc lifts them further.
Like wireless HD 650 sound with useful PEQ 2026-08-23
They both wouldn't exactly sound like what you have at home but the HDB 630 is definitely closer to that and it has that PEQ which is really useful, I think. It is kind of like a wireless closed-back version of the HD 650 with more bass. As for sound quality, the HDB 630 wins against the M5 for my personal taste *but* the M5 is a bit cheaper, has better ANC, a better transparency mode and a better case. So, it depends on what you value more.
Like biggest sound-quality jump vs momentum 4/5 2026-06-23
I‘d get either the M5 (especially if value much improved ANC and transparency modes over the M3) or the HDB 630 if you want the most noticeable jump in sound quality compared to both M4 and M5 even. However, if you’re still happy with your M3, keeping them for as long as possible surely is an option as well - they’re still great!
Like great wireless headphones 2026-06-11
HDB 630 are great wireless headphones! That stock tuning is almost flawless, imo. As for recommendations on Sennheiser open-back headphones for a new audiophile, I think you cannot go wrong with the HD 550, actually! They are comfortable, easy to drive, not all that expensive and sound great as well. They are also versatile in that they work nicely for gaming and are compatible withe the HD 500 BAM if needed.
Like preferred sound over the b&w px8 s2 in a head-to-head 2026-06-07
Keep which? PX8 S2 vs HDB 630 I bought both as they were on flash sale. I figure I buy both first before deciding on which to keep, this way I could lock in the discounts first. The prices are in SGD 630: S$536 ($415.54) PX8 S2: S$665 ($515.54) Ive tried both of them in store, but im torn. I REALLY love the look and feel of the PX8. But prefer the sound of the 630 slightly more. After EQing I was able to get the PX8 that much closer to the 630s, albeit still a little sharper and bassier. I wish the 630s had
Like sound clarity upgrade 2026-06-05
Got the HDB 630 today Initial impressions are that the sound clarity is a significant upgrade over my Momentum 4's. Slightly wider soundstage too - but the way I'd describe it is you can hear individual instruments much more clearly throughout the various ranges where they can get drowned out on the M4. Overall pretty happy with the upgrade. Ask me anything HDB 630 Momentum 4 HDB 630 Momentum 4
Like best sound quality in its class - clearly recommended over sony alternatives 2026-06-05
Get the HDB 630 if your main criteria is best sound quality. Ignore the other comment about getting the Sonys.
Like more tunable sound 2026-06-05
Px8 S2 vs hdb 630 Hello, I'm on the verge of buying one of those 2 headphones. Hdb 630 seems like the more logical choice in that its more tunable and the sound is less " opinionated" but I can't get over how ugly it looks. Big, plasticky and generally not good. Where as the px8 S2 looks amazing in my opinion but some people seems to hate the sound.. I'm favoring sound as #1 criteria and sadly since both bads ANC which would be my second criteria I would at least like something not terrible looking. Is the px8
Like bass lift 2026-05-01
1. iPhone and Mac user here - no volume issues at all for me. 2. The sound signature of the HDB 630 is neutral-ish but not like dead neutral and boring - there’s still a bass lift in the stock tuning e.g. I love the term „consumerphile“ for them ;) 3. I used APM (first gen) in the past and clearly prefer the HDB 630 here. Even more than that, they are my favorite wireless headphones, especially at this price point. All of that said, ultimately you and your own ears must be the deciding factor here.
Like easier and more pleasant to listen to 2026-03-14
Honestly, not even close. But, and this is a hot take, the HDB 630 is easier and more pleasant to listen to. As much as I praise the HD 800 and 800S for it's amazing imaging, texture, and lack of distortion, their frequency responses have much to be desired and I don't think they sound very natural (This is apparent when listening to vocal content that isn't music. Voices simply don't sound realistic)
Con Why owners dislike the way it looks and feels
Check audio quality degraded during gaming before buying Sennheiser HDB 630, especially if it affects your daily use case.
Complaint Bulky, plain-looking design 2026-08-23
Ditching HDB 630 to get Momentum 5 Don't get me wrong, HDB 630 are a great pair of headphones, but... they look kinda mid. Earcup width is little too wide and I also don't like the black color. The blue and white variants of Momentum 5 just look awesome and it's not even close. HDB 630 are phenomenal when it comes to soundtrack music. Hans Zimmer, OSTs of Minecraft, Subnautica, KCD. This is where they peak imo. However. I also listen to energetic music and I'm sorry to say this, but I miss the kick of EQed XM4 a

Complaint Not well built 2026-06-05
Honestly while they are ridicolously priced (ludicrous really) and they dont feel nearly as premium as comparable product (APM, PX8) they actually deliver a package no other headphone brings to the table. Bose has the weird adaptive anc, issues with the hinge design making noises while moving and very unnecessary codec limitations. PX8 has weak ANC and Mics. HDB 630 arent build very well and arent really comfortable. Momentum 5 only average ANC and build quality etc. The Collexion dont really miss in any spot (exc
Complaint can be bassy 2026-05-31
If you like your bass, wait for the M5 :) HDB 630 *can* be bassy (with EQ) but I wouldn’t buy it (just) for that. HD 480 is great and one of the most comfortable headphones out there. Not exactly overly bassy either but it has more bass impact than the HD 505 that you love so much. Your choice ;)

Buying Questions About Sennheiser HDB 630
Quick answers to the main review, complaints, buyer-fit, and comparison questions shoppers ask before choosing Sennheiser HDB 630.
Is the Sennheiser HDB 630 worth the money?
If you are buying purely for sound, the evidence is strongly in favour: nine owners rate the audio at the top of the wireless category and four prefer it to Sennheiser's own Momentum 4 and 5. The argument against is the object itself. Three owners criticise the build and looks, with one calling the price ludicrous relative to how premium it feels next to an AirPods Max or Px8.
Is the HDB 630 better than the Sennheiser Momentum 5?
On sound, four owners point that way. One says the 630 delivers the most noticeable jump in sound quality over both the M4 and the M5. Another who has used both gives the 630 the sound win for their taste, but is equally clear that the M5 is cheaper and has better ANC, a better transparency mode and a better case. So it depends whether you are buying a listening device or a travel headphone.
How does the HDB 630 compare with the B&W Px8 S2?
One owner bought both on flash sale specifically to decide, and after trying them in store prefers the sound of the 630 slightly, while loving the look and feel of the Px8. A second owner weighing the same two finds the 630 more tunable with a less opinionated sound, but cannot get past how big and plasticky it looks, and notes both have weak ANC. Two comparisons, both giving the 630 sound and the Px8 looks.
Is the HDB 630 build quality good?
This is the main complaint. Three owners raise it. One says plainly that the HDB 630 is not built very well and is not really comfortable, and that it does not feel as premium as comparable products at a price they describe as ludicrous. Another finds the earcups too wide and the design plain enough that they are switching to a Momentum 5. A third calls it big and plasticky.
Does the HDB 630 have good noise cancelling?
Not by the standards of its price. One owner who has used both says the cheaper Momentum 5 has better ANC and a better transparency mode. Another comparing the 630 against the B&W Px8 S2 describes noise cancelling as weak on both. Nobody in this evidence set praises the ANC, so if that is your priority the Momentum 5 is the better-aligned buy.
Why is my HDB 630 so quiet?
One owner hit exactly this and found the fix. Coming from a three-year-old Momentum 3, they were disappointed by the volume until they turned off volume normalisation in Spotify's settings, after which it became absurdly loud. They now run at 50 to 60 percent where they previously needed 90, and report the same on both Apple and Android.
