Sennheiser 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 can enjoy glorious audiophile sound quality anywhere.

Audiophile sound reinvented

Really serious listening used to require a whole set of heavy equipment. The HDB 630 changes that forever.

The quest for audiophile sound once meant high-end DACs that cost more than your first car, balanced cables and tube amplifiers you'd rather not take on a hike. Now you can take that same high-fidelity experience with you - with all the conveniences of modern wireless technology.

Thanks to the BTD 700 dongle, you can finally experience high-resolution wireless sound with a wide range of devices: phones, tablets and laptops. Regardless of which codecs your device supports, aptX Adaptive via the dongle ensures brilliant, hi-res sound quality. This turns even your smartphone into a high-quality audio source.

A perfectly orchestrated acoustic chain

Each component of the HDB 630 has been carefully designed to work in harmony to reveal details you've never heard before in wireless headphones.

The neutral, detailed mids make singers sound as if they are right in front of you. The wide soundstage enhances that immersive feeling as if you were in the middle of the musicians.

Such balanced high-res sound requires precision in acoustics, mechanics, materials and electronics. That's why every element of the acoustic chain has been optimized - from the 42 mm in-house transducer to the transparent mesh in the baffle. The deep back volume and new acoustic mesh ensure smooth upper mids and lower treble.

The result is a natural, balanced sound reproduction rarely found in a closed-back design. The HDB 630 delivers just that, with impressive adaptive noise reduction that keeps out interference without coloring the sound.

Checking every detail

Critical listening requires precision and complete control. That's why the HDB 630 offers advanced high-res codecs and features such as a crossfeed function and parametric equalizer.

Internal electronics preserve the purity of the signal from source to ear. aptX HD and aptX Adaptive deliver high-quality audio wirelessly, but if you want the very best, you can also listen via USB-C for lossless high-resolution audio.

Plus, there's an included audio cable that lets you connect via any 3.5mm jack for maximum compatibility. The powerful adaptive noise cancelling combined with the closed construction mutes the world without affecting the music, while the transparency mode allows you to hear your surroundings when needed.

The crossfeed feature is ideal for classic or older tracks with hard-panned mixes: instruments that are normally only in one channel are subtly balanced for a more natural and realistic stereo image - as if you were listening through a full speaker system.
