Sennheiser HDB 630: two-minute evaluate
What occurs whenever you lower 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 greatest? 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 realize 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 cellphone, pair it to the Sennheiser HDB 630, mkae certain your file high quality is of the specified commonplace and also you’re good to go.
After all, 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 fantastically balanced, textured, and well-separated efficiency of the HDB 630, which outperformed even a few of the greatest headphones I’ve examined on this price-range.
They’ve a impartial tuning out of the field, which loads of audiophiles will admire – the bass is way from overbearing, although it stays punchy and responsive. A bump within the higher midrange typically offers vocals a little bit bit of additional room to specific themselves too, whereas treble is managed and by no means too intense.
With parametric EQ and crossfade features, you can even 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 received’t get absolute top-tier noise-crushing skills right here, the HDB 630 had been in a position to maintain me fairly targeted 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 operate 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 may be very delicate, and the cans generally activate even with a small knock. All of this may be switched off, however rivals just like the Sony WH-1000XM6 supply far more intuitive controls.
Again to the positives although. One thing that actually wowed me in regards to the HDB 630 was their wonderful battery life. Contemplating loads 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 best way – 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 reality, aside 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’d 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 excellent.
Total, 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. Positive, there are a couple of imperfections right here and there, but when we’re speaking sound for pound (or greenback, and many others.) worth, then the Sennheiser HDB 630 are a tempting choice, and straightforward to advocate.

Sennheiser HDB 630 evaluate: 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
Relating to options, Sennheiser has put loads of care into delivering nearly every little thing you can need from wi-fi headphones.
Let’s begin with a few of the flashy inclusions that you simply’re not going to seek out from most rivals. First up, we’ve obtained parametric EQ. This grants customers with granular management over the frequency they need to change, together with achieve and Q-factor. So, should you’ve obtained a really exact sound in thoughts, you’ll simply have the ability 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 how you can get the perfect out of it. I usually 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 discuss crossfeed – one thing I’d by no means used on a rival pair of the greatest 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 many of the bass solely performs from the proper facet, say.
I attempted this function out with Purple Haze by Jimi Hendrix – a person who liked to maneuver sound throughout the stereo area for a novel listening expertise. When cranking crossfade as much as excessive, vocals – which initially had been targeted into the proper channel – had been considerably extra balanced. Personally, I had no subject with the unique sound, so I not often used crossfeed, nevertheless it does work effectively, and I’m certain some will take pleasure in utilizing it.
Maybe the star function of the HDB 630 is their higher-res Bluetooth audio assist. To utilize this, you’ll be able to plug within the included BTD 700 dongle, which opens up entry to aptX, aptX HD, and aptX Adaptive codecs – even should 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 implies that nice high quality music turns into accessible to simply about any trendy 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 received’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 best stability 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 had been principally inaudible. And that was when listening to music at about 60% quantity, by the best way. Some increased pitched sounds – like the clicking of seatbelts – did creep via, however I used to be nonetheless impressed with the HDB 630’s noise nixing abilities.
Adaptive mode is dynamic and efficient too, however you can even entry a transparency mode with the customized settings. This is a perfect choice should you’re somebody that prefers to have 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 plenty of 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 generally sounded fuzzy. The SoundConnectPlus app would additionally generally fail to work once I had the dongle inserted, although this wasn’t all the time the case. These points could 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 robust.
All in all, although, there’s simply a lot to sink your enamel into on the HDB 630, and if you need extremely customizable listening experiences, it doesn’t get significantly better than this.
Sennheiser HDB 630 evaluate: sound high quality
- Immersive, detailed audio efficiency
- Audiophiles will possible admire extra impartial default tuning
- Hello-res audio sounds unbelievable 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 pattern. I used to be very impressed with the readability, element, and width of the audio these headphones conjure up — and at this worth, you’re not going to seek out loads 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 typically given a elevate due to 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 loads 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 had been fastidiously separated from the pumping low-end and electronica within the background. Finer particulars like gentle percussion got here via clearly, whereas electrical guitars within the decrease mid-range – which might generally 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 form of monitor the HDB 630 might excel with. The upper-pitched vocals floated had been fantastically emotive and well-positioned within the combine, with gentle acoustic guitars, in addition to gentle 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 nearly otherworldly results that enter into the monitor had been exceptionally clear and well-positioned, although the bass itself – regardless of being speedy and responsive – lacked a little bit little bit of chew for my private style.
Fortunately, this wasn’t an excessive amount of of a difficulty, although. There’s a bass enhance toggle for moments the place you need a low-end elevate in a pinch, and in depth EQ presets and customized choices if you need a deeper tuning.
I attempted my very own customized tuning, utilizing parametric EQ, and Left And Proper by D’Angelo sounded extremely immersive, due to the managed, texture bass, expertly layered vocals, and impactful but disciplined percussion within the treble vary. The huge soundstage created an nearly three-dimensional listening expertise, and that’s one thing {that a} truthful few rivals on this worth vary can’t supply.
For reference, I spent the vast majority 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 fee – they ship precisely what they purpose to: audiophile-friendly sound, with out the cable.
Sennheiser HDB 630 evaluate: design
- Wired headphone vibe, wi-fi design
- May look a little bit extra premium, for my part
- Contact controls and auto-on really feel a little bit clumsy
It has been an nearly excellent begin for the HDB 630 thus far, however the design division is the place the image is a little bit bit extra combined.
First up, let’s discuss appears to be like. The HDB 630 have an look that is befitting of their function. Visually, they’re nearly extra like closed-back wired headphones, minus the wires – and I’m a fan of that synchronicity.
Nevertheless, for me, they simply don’t look fairly as premium as I’d hope for headphones on this worth vary. The silver sections that join the scarf to the earcups have an nearly plasticky look, which contrasts the luxurious-looking headband and leatherette earcups. They nonetheless look fairly good total, and that is largely a matter of non-public desire – however I feel some rivals, just like the Bowers & Wilkins Px7 S3 have a sleeker total 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 unintentionally play or pause my tunes.
Sadly, contact controls can’t be personalized – it is both on, or off – which is a little bit of a disgrace, as I’d’ve favored to attempt tailoring them to my preferences. To present 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 after they had been on my desk, they usually’d auto power-on, connect with my cellphone, and begin taking part in my music out. That was a little bit irritating, and led to me later turning the function off, although the good pause operate labored actually properly when eradicating or re-wearing the headphones.
On the optimistic facet, these headphones are pretty snug for longer listening periods. I undoubtedly assume 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. Additionally they supplied a safe match throughout my flight and each time I used to be out and about.
In contrast to headphones such because the Sony WH-1000XM4, the HDB 630 do not fold up. Meaning they don’t seem to be essentially the most compact round. However when you should take them out and about, you may make use of the included carry case, which is constructed to a excessive commonplace. It feels very sturdy, and is effectively protected towards scuffs or scratches. It is a little bit massive and makes use of a zipper slightly than my desire of magnets, nevertheless it’s nonetheless a really welcome inclusion.
Sennheiser HDB 630 evaluate: 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 opponents
Relating to worth for cash, the Sennheiser HDB 630 rating properly – sure, although they’re not the most cost effective headphones on the market.
For the cash you pay, you get completely fantastic sound high quality, and the inclusion of the BTD 700 dongle opens up higher-res Bluetooth listening to anybody – even iPhone listeners, who’re regularly 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 perfect at school however actually not dangerous. However they certain do stand out on the subject of 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 in 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 every single place I went. After all, I used them on the workplace throughout commonplace work hours, however I additionally used them at house, whereas out on walks, and even on a flight.
Whereas listening to music, I predominantly made use of Tidal with a view 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 acceptable, I in contrast the headphones towards my trusty Sony WH-1000XM6, which helped to evaluate features like sound high quality and design.
