Key Highlights
The Sennheiser HDB 630 is a closed-back, over-ear Bluetooth headphone with a design inspired by the Momentum series, featuring "Japanese Protein Leatherette" earpads and fingerprint-resistant earcups.
It supports SBC, AAC, aptX HD, and aptX Adaptive Bluetooth codecs, achieving up to 24-bit/96kHz audio quality, though this remains lossy; wired connections via USB-C and 3.5mm are also available for higher fidelity.
The Smart Control Plus app enables advanced sound customization with parametric EQ, crossfeed settings, and future social features like preset sharing via QR codes.
