Sennheiser HDB 630 Lunar Silver

Sennheiser HDB 630 wireless headphones combine exceptional sound quality with the convenience of wireless listening. They feature 42mm dynamic drivers which, together with a precisely tuned acoustic design, deliver neutral sound, natural mids and a wide soundstage. The closed-back design is complemented by adaptive hybrid ANC to reduce ambient noise. Bluetooth 5.2 technology with support for aptX HD and aptX Adaptive codecs enables high-quality wireless transmission, while USB-C offers the option of listening to high-resolution music. The headphones provide up to 60 hours of battery life on a single charge and allow detailed sound customisation via the Smart Control Plus app. The package also includes the Sennheiser BTD 700 Bluetooth adapter to expand your wireless connectivity options.

Precise acoustic design for neutral sound

The acoustic system of the HDB 630 has been engineered with an emphasis on the synergy of individual structural elements. The deep rear chambers of the drivers, together with a new acoustic mesh, help achieve smooth reproduction of the upper mids and lower highs. The transparent mesh in the acoustic baffle is part of a design optimised for precise music reproduction. The result is a spatially open sound signature with outstanding separation of individual instruments and voices. The neutral character of the reproduction allows recording details to stand out during focused listening.

Detailed sound and environment customisation

The parametric equaliser in the Smart Control Plus app lets you adjust the sound using individual frequency bands and filters. You can set the centre frequency, bandwidth and the way the chosen filter behaves. The Crossfeed function balances distinctly separated left and right stereo channels, making older recordings more pleasant to listen to. Adaptive noise cancelling helps reduce distracting sounds when travelling by plane or public transport, while Transparency mode lets you stay aware of your surroundings as needed.

Comfort for long listening sessions and connectivity options

Large ear pads with soft cushioning surround the ears and contribute to a comfortable fit. The headband, finished in Japanese synthetic leather, complements the low-pressure design. The included BTD 700 adapter enables high-resolution wireless audio streaming from a compatible source. For wired listening, you can use the digital USB-C connection or an analogue audio cable with a 3.5mm jack. The accessories are completed by a sturdy protective case and an in-flight adapter.
