Redefining audiophile listening

Serious sound used to require serious gear — stacks of components, cables everywhere, and equipment you’d never carry outside the house. The HDB 630 changes that. It delivers true high-fidelity performance with all the convenience of modern wireless headphones.

The quest for audiophile sound often means expensive DACs, balanced setups, and bulky tube amps — amazing, but anything but portable. Now you can enjoy all the clarity, detail, and precision of a premium system in a sleek, cable-free design you can wear anywhere. And with the included BTD 700 USB-C Bluetooth® dongle, you get high-resolution wireless sound from most phones, tablets, and laptops — even if the device itself doesn’t support the best codecs. The dongle unlocks aptX™ Adaptive, turning your everyday device into a hi-res source.

Turning audiophile sound on its head


A perfectly tuned acoustic chain

Every component of the HDB 630 is engineered to work together in harmony, extracting details rarely heard from wireless headphones.

Neutral, highly detailed mids place vocals right in front of you, while a wide soundstage adds a natural sense of space, as if you’re in the room with the artist. Achieving this level of realism requires more than just a good driver — it takes careful integration of acoustics, mechanics, materials, and electronics. Our engineers optimized everything, from the in-house 42 mm transducer to the transparent baffle mesh, to achieve exceptional clarity and balance.

The deep back volume and newly designed acoustic mesh smooth out upper mids and lower treble, resulting in a natural, even presentation — something rarely found in closed-back headphones. Yet the HDB 630 manages it effortlessly, and when paired with outstanding adaptive noise cancellation, it delivers high-fidelity listening anywhere, without distractions.

A perfectly orchestrated acoustic chain


For those who demand control

Critical listening requires precision — and the HDB 630 delivers with high-resolution codecs, advanced signal processing, and deep customization tools.

Its internal electronics keep your audio pristine from source to ear. aptX™ HD and aptX™ Adaptive offer high-quality wireless playback. For lossless listening, simply plug in via USB-C. And for maximum compatibility, an analog 3.5 mm cable is included.

Adaptive noise cancellation blocks the outside world without touching your music, while transparency mode lets you hear your surroundings instantly. The crossfeed feature is perfect for older recordings with extreme left-right panning — it naturally blends channels to recreate the feel of a full stereo system.

Control freaks, it's your time to shine


Parametric EQ: Precision without limits

Most equalizers are restrictive. The HDB 630’s parametric EQ, available in the Smart Control Plus App, gives you full control — down to the exact frequency, bandwidth, and filter type.

Unlike standard graphic EQs with fixed bands, the parametric EQ lets you decide where and how to adjust. Boost vocals exactly where you want them, tame brightness without dulling the mix, or fine-tune bass without touching the mids. It’s a level of customization rarely found in wireless headphones, perfectly complementing the HDB 630’s audiophile tuning.

Crossfeed, parametric EQ, ANC settings, advanced audio options, and firmware updates — all are easily managed in the Smart Control Plus App.

Comfort and endurance for the long haul

A great headphone should disappear on your head — even during marathon listening.

With up to 60 hours of battery life, the HDB 630 keeps going for days. Long trips, long work sessions, long playlists — no charging anxiety.

To match that endurance, comfort is essential. The earcups are generously sized with luxurious pads, and the headband is wrapped in premium Japanese leatherette. The lightweight design and gentle clamping force make them easy to wear for hours at a time.

It’s the rare combination of audiophile sound, wireless freedom, long-lasting comfort, and top-tier control — making the HDB 630 a headphone you’ll never want to take off.

Stay comfortable and stay connected
