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.

The in-house 42 mm transducer delivers neutral sound with lifelike mids, stunning detail, and a wide soundstage.

Enjoy high resolution with support for aptX™ HD and aptX™ Adaptive, especially when paired with the included BTD 700 Bluetooth® USB C Dongle

For the purest signal, connect via USB C or analog input for lossless listening at up to 24 bit/96 kHz.

Parametric equalizer for advanced equalization and the crossfeed feature give you complete control of your sound.

Powerful adaptive noise cancellation blocks distractions without degrading clarity, dynamics, or balance.

Listen for days, not hours, with up to 60 hours of battery operation.
