Sennheiser HDB 630: two-minute overview
What occurs while you minimize the wires off your audiophile-grade headphones and match a Bluetooth module inside, then add a USB-C dongle to the field so individuals can hear them at their finest? You get the Sennheiser HDB 630. These wi-fi headphones are supposed to ship ‘hi-res’ Bluetooth audio to anybody, irrespective of which smartphone you’re utilizing – sure, even an iPhone.
To attain this, Sennheiser has bundled in its BTD 700 dongle, which opens up entry to the aptX, aptX HD and aptX Adaptive codecs, and as much as 24-bit / 96kHz streaming high quality. Simply plug the USB-C dongle into your telephone, pair IT to the Sennheiser HDB 630, mkae certain your file high quality is of the specified customary and also you’re good to go.
In fact, some information is misplaced when streaming over Bluetooth, however nonetheless, the audio high quality right here is outstanding and deserving of Sennheiser’s HD (ie. reference grade) lineup. I used to be very impressed by the superbly balanced, textured, and well-separated efficiency of the HDB 630, which outperformed even a few of the finest headphones I’ve examined on this price-range.
They’ve a impartial tuning out of the field, which a variety of audiophiles will respect – the bass is way from overbearing, although IT stays punchy and responsive. A bump within the higher midrange usually offers vocals a little bit bit of additional room to precise themselves too, whereas treble is managed and by no means too intense.
With parametric EQ and crossfade features, you may also adapt the sound to your particular tastes – there’s a lot customizability to entry with the Sennheiser SmartControlPlus companion app.
And that applies to extra than simply sound. There’s customizable lively noise cancellation, together with a transparency mode, and a standalone adaptive configuration. These all work successfully, and though you gained’t get absolute top-tier noise-crushing talents right here, the HDB 630 have been in a position to hold me fairly centered on my music throughout a flight and when working at my workplace.
One factor that I want was a little bit extra tweakable, although, is the contact controls. A few of these perform decently, however a pair really feel a little bit clumsy to make use of, like quantity adjustment and a single-touch play/pause choice. Equally, the On-head Detection could be very delicate, and the cans typically activate even with a small knock. All of this may be switched off, however rivals just like the Sony WH-1000XM6 supply way more intuitive controls.
Again to the positives although. One thing that actually wowed me concerning the HDB 630 was their glorious battery life. Contemplating a variety of high-level rivals on this vary solely supply round 30 hours of playtime, the 60 hours you get right here – with ANC on, by the way in which – is totally distinctive. I barely ever needed to cost these cans throughout my month of testing, and that in itself is a large profit.
In truth, apart from the marginally unrefined contact controls, most of my criticisms are minor. I skilled a couple of inconsistencies with mic high quality when utilizing the BTD 700 dongle, and I might say that these aren’t fairly the comfiest cans ever. However nonetheless, they’re comfortable sufficient to maintain on for longer listening periods, and with out the dongle, the mic high quality is superb.
General, these cans make a spectacular wi-fi debut into Sennheiser’s beloved HD6XX line. They provide revealing, immersive audio, buckets of playtime, and a wealthy set of options. Certain, there are a couple of imperfections right here and there, but when we’re speaking sound for pound (or greenback, and so forth.) worth, then the Sennheiser HDB 630 are a tempting choice, and straightforward to suggest.

Sennheiser HDB 630 overview: options
- Effectively-engineered adaptive ANC and passthrough modes
- Fleshed-out companion app with parametric EQ and crossfeed
- Comes with Sennheiser BTD 700 transmitter for higher Bluetooth audio
When IT involves options, Sennheiser has put a variety of care into delivering nearly the whole lot you could possibly need from wi-fi headphones.
Let’s begin with a few of the flashy inclusions that you just’re not going to search out from most rivals. First up, we’ve acquired parametric EQ. This grants customers with granular management over the frequency they need to change, together with achieve and Q-factor. So, when you’ve acquired a really exact sound in thoughts, you’ll simply be capable to adapt the headphones to IT.
In my expertise, parametric EQ labored very properly, and there are clear directions within the Sennheiser SmartControlPlus app for the best way to get the most effective out of IT. I typically caught with the default sound, however tried making an altered tuning with a slight low-end bump, which was enjoyable to configure.
Subsequent, let’s speak about crossfeed – one thing I’d by no means used on a rival pair of the most effective over-ear headphones. Primarily, this can be utilized to mix the left and proper audio channels for a extra balanced presentation – particularly helpful if a recording has excessive channel separation and a lot of the bass solely performs from the suitable aspect, say.
I attempted this function out with Purple Haze by Jimi Hendrix – a person who cherished to maneuver sound throughout the stereo area for a novel listening expertise. When cranking crossfade as much as excessive, vocals – which initially have been centered into the suitable channel – have been considerably extra balanced. Personally, I had no subject with the unique sound, so I hardly ever used crossfeed, however IT does work effectively, and I’m certain some will get pleasure from utilizing IT.
Maybe the star function of the HDB 630 is their higher-res Bluetooth audio help. To utilize this, you possibly can plug within the included BTD 700 dongle, which opens up entry to aptX, aptX HD, and aptX Adaptive codecs – even when you’re on iPhone.
Anyway, the BTD 700 will allow you to stream audio in higher-than CD high quality – 24-bit / 96kHz (albeit with some loss incurred by Bluetooth transmission itself). That signifies that nice high quality music turns into obtainable to only about any fashionable machine – extra on the precise audio efficiency later, although.
One other one of many HDB 630’s main options is lively noise cancellation. I used to be more than happy with the general efficiency right here, even when IT gained’t evaluate to main gamers on this area, just like the Bose QuietComfort Extremely Headphones Gen 2. One small factor: the HDB 630 set the ANC degree to 60% by default, maybe for the perfect steadiness sonically, however for testing functions I cranked this as much as 100%.
On a flight to Copenhagen, the low rumble of the jet engine was massively subdued, whereas discussions round me have been principally inaudible. And that was when listening to music at about 60% quantity, by the way in which. Some greater pitched sounds – like the clicking of seatbelts – did creep by means of, however I used to be nonetheless impressed with the HDB 630’s noise nixing abilities.
Adaptive mode is dynamic and efficient too, however you may also entry a transparency mode with the customized settings. This is a perfect choice when you’re somebody that prefers to have a very good measure of your environment. There’s additionally an choice to activate anti-wind noise, or just flip noise cancelling off solely.
Sound zones is one other attention-grabbing function that allows you to set an EQ preset and ANC degree relying in your location. It can save you numerous places, and the headphones will seamlessly slip into your chosen settings, as long as you’re inside a sure radius of the related space.
A fast phrase on battery life too. You get an impressive 60 hours of playtime from the HDB 630, even with ANC on. That’s very spectacular certainly, and matches the battery lifetime of the five-star-rated Sennheiser Momentum 4 Wi-fi.
One key subject I bumped into throughout my time with the HDB 630, was that decision and recording high quality would endure considerably if I used to be utilizing the BTD 700 dongle. Equally, if I ended a name, when my music continued to play IT typically sounded fuzzy. The SoundConnectPlus app would additionally typically fail to work after I had the dongle inserted, although this wasn’t all the time the case. These points might be solvable with updates and such – however the name high quality subject was particularly unlucky, as with out the dongle, name high quality on the HDB 630 is powerful.
All in all, although, there’s simply a lot to sink your enamel into on the HDB 630, and if you would like extremely customizable listening experiences, IT doesn’t get significantly better than this.
Sennheiser HDB 630 overview: sound high quality
- Immersive, detailed audio efficiency
- Audiophiles will possible respect extra impartial default tuning
- Hello-res audio sounds incredible with BTD 700 transmitter
Now, for anybody acquainted with Sennheiser’s title, you’ll know that the corporate is thought for knocking out stellar sounding audio gear time after time. And the HDB 630 proceed that development. I used to be very impressed with the readability, element, and width of the audio these headphones conjure up — and at this value, you’re not going to search out a variety of rivals that do higher.
The HDB 630 have a fairly impartial sound out of the field. Bass is punchy, however not overly assertive, with a major dip within the sub-100Hz vary in comparison with the Momentum 4. Mids by no means get drowned out, with vocals usually given a raise because of a slight bump within the higher mid-range. In the meantime, treble is probably a little bit extra tempered than I’m used to on a variety of wi-fi headphones, however this leads to a managed presentation, with sounds within the upper-range by no means coming throughout as over-eager or tinny.
When listening to Black Eye by Allie X, I used to be impressed with the brilliantly outlined, assertive vocals, which have been fastidiously separated from the pumping low-end and electronica within the background. Finer particulars like gentle percussion got here by means of clearly, whereas electrical guitars within the decrease mid-range – which might typically sound muddied with middling or poor high quality cans – got a good quantity of room to play.
Rains once more by Solji – a softer ballad – was the precise type of monitor the HDB 630 may excel with. The upper-pitched vocals floated have been superbly emotive and well-positioned within the combine, with smooth acoustic guitars, in addition to smooth strings and keys all replicated in a tonally correct, expressive method.
Turning to a deeper monitor like Spaceship by Marsolo, that is the place issues might require some tweaking. The ambient sounds and virtually otherworldly results that enter into the monitor have been exceptionally clear and well-positioned, although the bass itself – regardless of being fast and responsive – lacked a little bit little bit of chunk for my private style.
Fortunately, this wasn’t an excessive amount of of a problem, although. There’s a bass increase toggle for moments the place you need a low-end raise in a pinch, and intensive EQ presets and customized choices if you would like a deeper tuning.
I attempted my very own customized tuning, utilizing parametric EQ, and Left And Proper by D’Angelo sounded extremely immersive, because of the managed, texture bass, expertly layered vocals, and impactful but disciplined percussion within the treble vary. The large soundstage created an virtually three-dimensional listening expertise, and that’s one thing {that a} honest few rivals on this value vary can’t supply.
For reference, I spent nearly all of my time listening with the BTD 700 dongle and the aptX Adaptive codec – this genuinely makes a distinction with the HDB 630, opening up a extra full-sounding, revealing hear. I additionally tried wired listening, and was once more delighted with the responsive, elegantly balanced efficiency of the HDB 630. These are an excellent-sounding pair of headphones for the associated fee – they ship precisely what they purpose to: audiophile-friendly sound, with out the cable.
Sennheiser HDB 630 overview: design
- Wired headphone vibe, wi-fi design
- Might look a little bit extra premium, in my opinion
- Contact controls and auto-on really feel a little bit clumsy
IT’s been an virtually good begin for the HDB 630 to this point, however the design division is the place the image is a little bit bit extra combined.
First up, let’s speak about seems. The HDB 630 have an look that’s befitting of their objective. Visually, they’re virtually extra like closed-back wired headphones, minus the wires – and I’m a fan of that synchronicity.
Nevertheless, for me, they only don’t look fairly as premium as I’d hope for headphones on this value vary. The silver sections that join the scarf to the earcups have an virtually plasticky look, which contrasts the luxurious-looking headband and leatherette earcups. They nonetheless look fairly good general, and that is largely a matter of private choice – however I feel some rivals, just like the Bowers & Wilkins Px7 S3 have a sleeker general aesthetic.
One thing that’s much less subjective, nonetheless, is the standard of contact controls on the HDB 630. Personally, I’m a contact controls man – controversial, I do know. However I didn’t all the time discover them to be intuitive right here. When flicking up, quantity would often rise too drastically, and the only contact requirement to pause music meant that IT was too simple to by accident play or pause my tunes.
Sadly, contact controls can’t be custom-made – IT’s both on, or off – which is a little bit of a disgrace, as I might’ve favored to strive tailoring them to my preferences. To offer the HDB 630 their flowers, some features, like skipping or returning to the earlier monitor, labored nice. Name controls functioned effectively too.
IT was an identical story with On-head Detection, which appeared a little bit clumsy. On a few events, I’d give the headphones a knock once they have been on my desk, they usually’d auto power-on, hook up with my telephone, and begin taking part in my music out. That was a little bit irritating, and led to me later turning the function off, regardless that the sensible pause perform labored actually properly when eradicating or re-wearing the headphones.
On the optimistic aspect, these headphones are pretty snug for longer listening periods. I undoubtedly suppose that my day-to-day headphones, the Sony WH-1000XM6 really feel lighter and comfier in-use, however the HDB 630 didn’t really feel tight on my head or harsh on my ears. In addition they provided a safe match throughout my flight and each time I used to be out and about.
Not like headphones such because the Sony WH-1000XM4, the HDB 630 don’t fold up. Meaning they’re not essentially the most compact round. However when you have to take them out and about, you can also make use of the included carry case, which is constructed to a excessive customary. IT feels very sturdy, and is effectively protected towards scuffs or scratches. IT’s a little bit giant and makes use of a zipper moderately than my choice of magnets, however IT’s nonetheless a really welcome inclusion.
Sennheiser HDB 630 overview: worth
- Pretty priced for the sound high quality on supply…
- …even when you will get higher ANC and luxury from some rivals
- Unimaginable feature-set, even towards rivals
When IT involves worth for cash, the Sennheiser HDB 630 rating properly – sure, regardless that they’re not the most affordable headphones on the market.
For the cash you pay, you get completely great sound high quality, and the inclusion of the BTD 700 dongle opens up higher-res Bluetooth listening to anybody – even iPhone listeners, who’re ceaselessly left behind in that area.
Even in a side-by-side comparability with my equally priced Sony WH-1000XM6, I felt that the HDB 630 carried out exceptionally, providing a barely extra open, revealing sound. The XM6 arguably have a extra ‘thrilling’ profile out of the field, however with a little bit tuning, there’s not a lot the HDB 630 can’t do.
Appears-wise and comfortability-wise, the HDB 630 are stable – not the most effective in school however actually not dangerous. However they certain do stand out when IT involves options. Parametric EQ, crossfade, adaptable ANC, and a ton of battery life. All of that mixed with the sound you get? That’s loads of bang on your buck.

How I examined the Sennheiser HDB 630
- Examined for one month
- Used within the workplace and on a flight
- Predominantly examined utilizing Tidal
I spent one month testing the Sennheiser HDB 630, taking them nearly in all places I went. In fact, I used them on the workplace throughout customary work hours, however I additionally used them at dwelling, whereas out on walks, and even on a flight.
Whereas listening to music, I predominantly made use of Tidal with the intention to benefit from the 24 bit / 96 kHz high quality audio – one thing that Spotify lossless isn’t able to. I tuned into the TechRadar testing playlist, which options tracks from a variety of genres, but in addition bumped a variety of songs from my private music library.
On prime of that, I exhausted the assorted options on the HDB 630, like crossfeed, parametric EQ, and ANC. The place applicable, I in contrast the headphones towards my trusty Sony WH-1000XM6, which helped to evaluate points like sound high quality and design.
