Sennheiser has set a new benchmark for high-end wireless listening with the HDB 630, its first truly high-resolution audiophile wireless headphones — blending the sonic purity of the iconic HD 600 series with the comfort and portability of the Momentum lineup.

High-Res Sound, No Compromise
The HDB 630 aims to deliver studio-grade detail without the wire. It comes bundled with Sennheiser’s BTD 700 USB-C hi-res Bluetooth transmitter, enabling 24-bit/96kHz streaming via the aptX Adaptive codec — even on smartphones that don’t support high-res Bluetooth natively.
This small dongle instantly expands hi-res support to nearly 80% of devices, intelligently adjusting bitrate and resolution to maintain stable playback even in crowded wireless environments.
Refined Acoustics and Build
Inside, a pair of 42mm drivers tuned with “pure audiophile precision” promise exceptional balance — smooth upper mids, extended treble, and deep, clean bass response across a 6Hz–40kHz range. The closed-back design keeps your sound intimate while adaptive ANC eliminates external distractions.
Listeners can also go wired for lossless playback using the included USB-C and 3.5mm cables.
Smart Customization for Audiophiles
Through the Smart Control Plus app, users gain access to an advanced Parametric EQ and crossfeed tuning — inspired by Sennheiser’s flagship HE 1 system.You can sculpt your frequency curve in fine detail, perform A/B comparisons, and even share custom EQ presets via QR codes after an upcoming software update.

Comfort and Endurance
The Japanese Protein Leatherette headband and fingerprint-resistant earcups ensure lasting comfort and premium durability. Battery life is equally impressive — 45 hours of playback with ANC on, extending to 60 hours with standard Bluetooth streaming.
