High-resolution revolution

​The world-class transducer system is propelled by a high-resolution digital audio engine that can be used wired or wirelessly in a variety of setups. Through the HDB 630’s USB Type-C port or analog headphone cable, audiophiles can connect directly to their local or streaming library, with native support for music up to 24-bit, 96 kHz resolution. For untethered listening, Bluetooth 5.2 with aptX Adaptive codec support provides robust streaming capabilities that prioritize sound quality and signal stability.

The headphone also includes a USB Type-C transmitter dongle, instantly upgrading class compliant sources like smartphones and tablets to high-resolution aptX Adaptive capability. With only an estimated 16% of smartphone hardware supporting native wireless high-res sound, the included dongle brings this capability to 80% of smartphone models in an instant through their USB Type-C port.

Brand new tools

The HDB 630 includes a swathe of fresh, shareable sound shaping tools to let listeners go beyond the genre presets, and 5-band equalizer modes found in the Smart Control Plus app. Inspired by the flagship HE 1, the Crossfeed feature gently blends the left and right channels, giving the HDB 630 a speaker-like presentation—perfect for hard-panned mixes that can be fatiguing for headphone listening. A groundbreaking new Parametric Equalizer lets listeners boost and cut frequencies beyond those offered in a traditional graphic EQ interface, complete with user-adjustable bandwidth (Q) controls, filter types, an A/B toggle and more. The settings are applied to the headphone’s advanced processing system, letting audiophiles enjoy their preferred tuning regardless of the content or app feeding it earlier in the chain.

Users can share their favorite presets with through the app, unlocking entirely new ways to experience high-resolution audio. A future update will enable preset sharing through QR code generation—a boon for audiophiles who experiment and document their pursuit of the perfect sound in their enthusiast communities. With Smart Control Plus users can further customize intelligent features like noise cancellation, on-head detection, codec preference, and more.
