Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: which current five-star wireless headphones is the brand’s best?

Sennheiser has been enjoying a good few months.

The HDB 630 made its debut in late 2025 to acclaim from our reviews team, who dubbed them some of the best wireless headphones they had heard at this premium level. A few months later, the Momentum 5 Wireless landed and, at their slightly lower price, matched their bigger brothers in earning the full five-star haul.

Great news for Sennheiser, then. But, with both premium wireless headphones accumulating significant plaudits, which do you go for? To make the decision easier, we have broken down each pair’s strengths and limitations across a range of parameters so that you can be sure you’re getting the Sennheisers that suit your needs.

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: price

These are both premium wireless headphones, so you’re not going to be able to pick up a pair for the same price as your morning coffee order. Well, unless you happen to frequent a very boujee coffee shop.

At £330 / $400 / AU4749, the Sennheiser Momentum 5 Wireless are the cheaper of the two, with a price that undercuts that of many of the established cans at this level.

At £400 / $500 / AU$1000, the HDB 630 are slap bang in the middle of what we’d call classic premium territory – not overpriced, but certainly par for the course in the world of flagship wireless over-ears.

Still, they are undeniably more expensive than their younger siblings, so it’s the Momentum 5 Wireless winning this one.

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: design and comfort

Sennheiser tends to have a pretty distinct design language, one that’s very much on display with both of these premium pairs.

The large oval earcups of the Momentum 5 Wireless and HDB 630 will be familiar to anyone who has seen a pair of recent wireless Sennheiser over-ears. Little touches, though, such as the attractive fabric exterior, do make the Momentum 5 actually seem a little more premium than the rather plain HDB 630.

The Momentum 5 Wireless are also a little smaller and lighter than their bigger brothers, weighing in at 290g compared with the 311g of the HDB 630. Much of that weight is housed in the HDB 630s’ earcups, which are chunkier and sport a deeper profile than those of the fifth-gen Momentums.

Comfort isn’t a problem on either pair, though. The Momentum 5 Wireless do cause some mild on-ear heating past the hour mark (many premium headphones of this type do), but we rarely experience that dull aching that you might suffer from with rivals sporting heavier weight or higher clamping pressure.

They are secure and stable, too. Even when we’re walking pretty briskly with the Momentum 5 Wireless clamped over our head, there’s little on-ear rocking or instability thanks to the headphones’ well-judged clamping force.

In fairness to the larger HDB 630, they are hardly a chore to wear either. Yes, they’re heavier overall, but the more costly cans do have slightly plusher ear padding, as well as a nicely cushioned headband, making for a comfortable, amply sealed listen.

Both pairs use touch controls rather than a predominantly button-based system, and we struggle to find any complaints with how they are implemented. We like that every touch action is acknowledged with a sound, that controls can be switched off via the app, and that our commands are responded to promptly whenever we tap or swipe on the right earcup.

It’s a tricky one. The Momentum 5 Wireless are lighter and more appealing to look at, but the HDB 630 do win back marks thanks to their slightly more luxurious earpads and headband. A tie seems like a fair result.

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: features

Let’s start with the basics.

Sennheiser has gone big on battery life both both its premium players, with the Momentum 5 Wireless squeezing out 57 hours when active noise cancelling (ANC) is switched on and the HDB 630 just pipping them to the post with 60 hours under the same conditions.

On both, Multipoint Bluetooth is available for connecting to two devices simultaneously.

If you want spatial audio with the Momentum 5 Wireless, Dolby Atmos is on the menu when listening to supported Atmos content, with head tracking to be added via an upcoming firmware update. Be aware, conversely, that the HDB 630 don’t support spatial audio.

Dolby Atmos can be toggled on and off via the Sennheiser SmartPlus app, a platform which we find ourselves really admiring the more we use it. It’s clean and orderly, and we like the levels of customisation on offer, such as the eight-band custom equaliser and a slider for dialling up and down the strength of the ANC.

For the Momentum 5 Wireless, Bluetooth codec support is impressive, with support for the routine SBC and AAC codecs alongside higher-quality aptX HD, aptX Lossless and aptX Adaptive flavours. The cans currently use Bluetooth 5.4, but an incoming firmware update later in 2026 will push this to 6.0 and include LE Audio.

With the HDB 630, codec support comes down to the inclusion of the headphones’ included Bluetooth dongle. The HDB 630 bundle in a BTD 700 USB-C dongle that you simply plug into your smartphone device’s USB-C port to give it up to aptX Adaptive superpowers, even if the source device natively doesn't support a higher-resolution codec.

That means you can stream in aptX Adaptive quality from the usually-AAC-only iPhone, for example. You can check the quality of the signal path in the Sennheiser Smart Control Plus app’s settings, and you’ll want to ensure the ‘Audio mode priority’ is set to ‘Hi-Res 24bit/96kHz’.

You don't get Dolby Atmos with the HDB 630, but there is a ‘Crossfeed’ feature to blend left and right channels for what Sennheiser calls a “more natural sound” with certain recordings. A bass-boost button, which does exactly what you think it does, is available for both.

A close one again, with solid showings across the board. But we feel that the dongle, plus a slightly better battery life, tip things over into the HDB 630s’ favour.

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: ANC and call quality

Noise cancelling is acceptable on both the Sennheiser HDB 630 and the Momentum 5 Wireless. It won’t be troubling the likes of the Bose QuietComfort Ultra Headphones (2nd Gen) or the Sony WH-1000XM6 class leaders, but each outshines the rather weaker efforts of the Bowers & Wilkins Px7 S3.

In fact, there isn’t a huge amount to choose between the two Sennheisers. Each pair is capable of dealing with the basic humming of an air-conditioning unit during a hot day in May, all but blocking out that droning sound so that it doesn’t intrude upon our listening in any meaningful way.

Traffic noises prove a little trickier, but again, there isn’t a huge difference between the two. We feel that the HDB 630 offer a little more passive isolation due to their larger, plusher earpads, but standing next to a busy road sees both pairs dampening, not eliminating, the swooshing of cars as they pass by.

Low-frequency rumbles are perceptibly reduced, but again, they don’t disappear entirely, while high-end sound such as tweeting birds will often pass through.

Call quality is excellent no matter your choice. We take the Momentum 5 Wireless out for a chat on a blustery day, and our headphones effectively reduce intrusive wind and traffic noise while making human speech sound clear and natural.

The HDB 630 do a similarly fine job, and once again, voices come across as articulate and human rather than mechanical or robotic. Isolation is decent, too, so no need to worry about having to shout to be heard over surrounding noises.

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: sound quality

If you like rich, smooth-sounding headphones that dig out plenty of detail and strike a fine balance precision and authority, the Momentum 5 Wireless could well be for you.

As we wrote in our review, the fifth-gen Sennheiser over-ears are “rich, smooth yet strikingly precise and detailed headphones, with an audio signature that makes listening a refreshingly undemanding experience. Sugar’s If I Can’t Change Your Mind can sound overly urgent or shrill... but the Momentum 5 Wireless have the poise and maturity to bring order to... chaos.”

If you’re after headphones that shine a sweet spotlight on your music’s midrange, the Momentum 5 Wireless demand an audition. The bass is full and a little on the rich side, but that poised midrange is a real highlight, offering a naturalness and insight that gives even more premium alternatives a run for their money.

Their qualities are further amplified when we use a wired connection, especially if you’re listening via USB-C for handling files up to 24-bit/96kHz. A wired connection lends further fullness and depth to instruments, while that outstanding midrange sounds sweeter and even more starkly defined.

In truth, the Momentum 5 Wireless never fatigue nor frustrate, instead letting music unfold naturally and precisely no matter the genre.

As you would perhaps hope, the step-up HDB 630 do take things up a notch. They’re a chunk more costly, but you’ll be rewarded handsomely by the sonic dividends that extra outlay grants.

In fact, these might well be the best-sounding premium headphones currently available – and that’s even before that clever Bluetooth dongle is in play.

Here, precision and analysis go hand in hand with drive and vigour, making for the most informative and entertaining sound we’ve heard from wireless headphones at this price, with or without the use of the dongle for higher-quality streams.

The HDB 630 are hugely natural and dare we say sophisticated-sounding wireless headphones, with a poise and precision that demands to be heard. As we wrote at the time, these Sennheiser premium cans are “wonderfully smooth and natural sounding headphones, full of shape and dynamism across the frequency range”.

Instrumental textures are replete with both depth and shape, and the HDB 630 are remarkably insightful at teasing out the emotional heart of our testing catalogue. Songs are conveyed with conviction and gusto, and the Sennheisers seamlessly switch emotional gears as they tackle our tunes with gusto and grace.

Yes, the Momentum 5 Wireless are detailed and well organised, but the HDB 630 really take things up a notch in practically all sonic departments. That becomes only truer when the dongle is called into action. And you’ll notice tangible gains in clarity and solidity when upgrading from, say, a standard AAC stream to full-fat aptX Adaptive.

However you listen, the HDB 630 are genuine benchmark-setters. The Momentum 5 Wireless are great, but the HDB 630 are ‘Great’ with a capital ‘G’.

** Winner: Sennheiser HDB 630 **

Sennheiser Momentum 5 Wireless vs Sennheiser HDB 630: verdict

If you can’t stretch to the HDB 630, the Momentum 5 Wireless are the logical step-down choice. They still provide excellent sound quality and bring plenty of high-performance features to enjoy, all while saving you £80 / $100 in the process.

That’s not an inconsiderable amount of money, so we completely understand why money-savvy buyers would – indeed should – pick the Momentum 5 Wireless over their bigger brothers if costs are a factor.

If you’re happy to spend more, however, go for the Sennheiser HDB 630. They are essentially in a sonic class of one at the moment, outshining not only the Momentum 5 but practically anything else we can think of at their level.

If sound is your top priority, there’s no real excuse for not checking them out.
