Sennheiser HDB 630

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. But now you can have your high fidelity and carry it, too — with all the conveniences of state-of-the-art wireless headphones.

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. A wide soundstage further enhances the feeling of being there with the musicians.

Carefully tuned, neutral, high-res sound like this requires acoustics, mechanics, materials, and electronics that complement each other perfectly. Our engineering team optimized every part of the acoustic chain from the 42 mm in-house transducer to the transparent mesh in the baffle to work together with exceptional balance and clarity.

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.

The HDB 630’s onboard electronics keep your music pristine from source to ear. 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. Not to mention the included audio cable, which lets you plug into any 3.5 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.
