For optimal versatility, the HDB 630 supports multiple connectivity options. Enjoy lossless playback at up to 24-bit/96 kHz using the USB-C or analog input, or stream wirelessly using the included dongle for uncompromised quality. The powerful adaptive noise cancellation intelligently suppresses ambient distractions while preserving musical clarity and balance.

Designed for all-day comfort, the over-ear earcups feature soft leatherette cushions, while the ergonomic design ensures a secure fit for extended sessions. With up to 60 hours of battery life, the HDB 630 is built to handle even the longest playlists and commutes with ease.

Each component in the HDB 630’s acoustic chain is fine-tuned for synergy, delivering a clean, neutral sound that minimizes masking and maximizes vocal detail. Its refined tuning emphasizes clear midrange, controlled bass, and smooth treble without fatigue-inducing peaks or dips—perfect for long listening sessions and critical evaluation.
