Get it All with the HDB 630 You want it all. High resolution, neutral tone, extra-long battery life, flawless active noise cancellation, and of course, no more cables.

Meet the closed-back HDB 630. With the included BTD 700 Bluetooth® USB C Dongle, you’re free to enjoy glorious audiophile sound anywhere you go.

Turning audiophile sound on its head Serious listening used to require a serious amount of equipment. The HDB 630 changes the rules.

The pursuit of audiophile sound can get a bit gear intensive. High-end DACs that cost more than your first car did.

Balanced cables, big tube amps. Not exactly stuff you bring on a walk around the block.

Plus, thanks to the included BTD 700 Bluetooth® USB C Dongle, you can finally get high-resolution wireless sound from a wide range of devices including most phones, tablets, and laptops. No matter which codecs your device supports, you can enjoy brilliant aptX™ Adaptive with your HDB 630 and the dongle, since it’s an upgrade that makes your smartphone capable of delivering hi-res quality to your headphones.

A perfectly orchestrated acoustic chain Each component has been carefully crafted to work in harmony, revealing details you’ve never heard from wireless headphones before. Neutral yet detailed mids make it feel like singers are performing right in front of you.

Carefully tuned, neutral, high-res sound like this requires acoustics, mechanics, materials, and electronics that complement each other perfectly. The deep back volume and new acoustic mesh, for example, ensure smooth upper mids and lower treble.

The result is a natural and balanced sound experience typically unseen in a closed headphone. But the HDB 630 achieves this with a closed back.

Combined with outstanding adaptive noise cancellation, it gives you the ability to enjoy high fidelity anywhere with no distractions. Control freaks, it's your time to shine Critical listening demands state-of-the-art electronics and precise control.

That´s why we included high-res codecs and advanced capabilities like the crossfeed feature and parametric equalizer. aptX™ HD and aptX™ Adaptive Bluetooth® codecs recreate high-quality content wirelessly.

When you want the purest possible signal, you can also plug in via USB C and listen to high-resolution, lossless files. 5 mm jack for maximum compatibility.

Powerful adaptive noise cancellation in a closed architecture quiets the world without affecting your music, while transparency mode lets you hear your surroundings when needed. The crossfeed feature is great for classic tracks with hard-panned mixes.

It takes instruments concentrated on one channel and balances them out, creating a much more natural listening experience — like hearing the track on a full stereo system. Stay comfortable and stay connected A great headphone should take even epic playlists in stride.

With up to 60 hours of battery life, you can listen to music, podcasts, or videos literally for days. Go on a week-long trip, crush it in marathon work sessions, or binge videos on your tablet.

But for this level of endurance, the fit and feel have to be just right. That’s why the HDB 630’s earcups are generously sized with earpads that feel as luxurious as they look.

The headband is wrapped in refined Japanese leatherette. Low weight and a gentle clamping force make these headphones a joy to wear, even if you’re listening for hours.

It’s that elusive blend of long-haul performance and all-day comfort that will ensure these become your new favorite daily driver headphones. Product highlights Sennheiser’s in-house 42 mm transducer delivers neutral sound with lifelike mids, stunning detail, and a wide soundstage.
