Sennheiser HDB 630: Hi-Res Wireless Sound, 60 Hours at a Time

42 mm drivers, aptX HD and aptX Adaptive, hybrid adaptive noise cancelling and up to 60 hours of battery life, in a comfortable headphone with a parametric EQ in the Sennheiser Smart Control Plus app.

Built for Travel, Work and Long Listening Sessions

A good wireless headphone should last days, not hours, and stay comfortable. The HDB 630 pairs an extended battery with large earcups, plush earpads and a Japanese leatherette headband.

Why the Sennheiser HDB 630 Stands Out
