Sennheiser has announced its new HDB 630 wireless headphones, which combine premium sound quality, smart ergonomics and impressive battery life.
The design is inspired by the Momentum 4 series and is complemented by soft Japanese protein leather ear cushions. At the heart of the headphones — large 42mm audio drivers that deliver Sennheiser’s signature sound. Connection is possible via a 3.5mm audio jack, USB Type-C cable or via Bluetooth 5.2. For smartphones, the company offers a separate BDT 700 USB transmitter with aptX Adaptive codec support.
HDB 630s support 24-bit audio transmission (96 kHz at 420 kbps) and offer minimal latency — as little as 80 ms. Features also include Adaptive Active Noise Cancellation (ANC) and Transparency Mode, which allows you to hear ambient sounds without removing the headphones.
