Sennheiser HDB 630 combines 42mm dynamic drivers, adaptive noise cancellation and detailed sound adjustment in a wireless headphone for focused listening. Parametric EQ lets you shape individual frequency regions, while crossfeed offers another way to adjust the stereo presentation. Transparency mode keeps nearby conversation accessible when you need it.
Bluetooth, USB-C audio and an analog input provide flexible source choices. USB audio supports up to 24-bit/96kHz, and the included BTD 700 USB-C Bluetooth dongle gives compatible computers and mobile devices another connection option. The analog cable has a 2.5mm plug at the headphone and a 3.5mm plug at the source. A carrying case, USB-C cable and airplane adapter are included.
Sennheiser rates battery life at up to 60 hours with ANC; runtime varies with use. In his Headphones.com review, Andrew Park (Resolve) praised its articulate bass and useful EQ, while noting fit-sensitive midrange, personal treble reservations and noise cancellation below his Sony and Bose comparisons.
