Awesome Audio. The Sennheiser HDB 630 Headphones w/ BTD 700 Bluetooth Adapter is designed specifically for the discerning ear. Comfortable ear cups house 42mm drivers that produce clear, detailed, and neutral audio. The HDB 630’s minimal digital processing keeps the output true to the source, leaving EQ controls in your hands.

Find Your Sound. The parametric EQ lets you customize how you like to listen, with specific adjustments for frequency bands, widths, and filters. Adaptive noice cancellation adjusts the volume based on your environment to maintain clarity and dynamics while minimizing distraction, and transparency mode keeps you alert when you need to be.

Stay Connected. Or Don’t. The HDB 630 headphones support USB-C for when you need true accuracy, providing lossless audio up to 24-bit / 96 kHz, but if you need to unplug, the BTD 700 Bluetooth adapter supports aptX HD, for peak wireless quality, and aptX Adaptive, for improved latency while retaining impressive sound. However you choose to listen, the 60-hour battery life gets you through a whole weekend, and a quick 10-minute charge powers the headphones for up to 7 hours.
