Sennheiser has introduced the HDB 630, a premium pair of over-ear wireless headphones built for high-resolution listening without sacrificing comfort or battery life. With 42 mm drivers, plush Japanese protein leatherette ear cushions, and a frame inspired by the brand’s Momentum 4 line, the HDB 630 aims to deliver long-wear comfort and refined sound for discerning listeners.
Tuning is a major focus. Through the Smart Control Plus app, you can shape your sound with a parametric equalizer, blend left and right channels to taste, and even share your custom profiles with others. Adaptive active noise cancellation keeps distractions out, while a transparency mode lets you hold conversations or stay aware of your surroundings at the press of a button.
Connectivity is flexible. In addition to Bluetooth 5.2, the HDB 630 supports both wired 3.5 mm analog and USB-C digital audio. A standout inclusion is the BDT 700 USB-C transmitter dongle, which brings aptX Adaptive to phones that don’t natively support it. That codec dynamically balances latency and quality, targeting as low as 80 ms of delay and up to 24-bit/96 kHz audio at bitrates up to 420 kbps. Details on LDAC support have not been announced.
Battery life is rated at up to 60 hours on a single charge. When you’re running low, a quick 10-minute top-up can add as much as 7 hours of listening, making these headphones practical for travel and daily commuting.
