The Sennheiser HDB 630 redefines what premium headphones can offer for music lovers and audiophiles alike. Designed to bring high-resolution sound to life wherever you go, these headphones combine cutting-edge engineering, thoughtful comfort, and powerful customisation tools to deliver listening experiences that feel personal and immersive.
Design and Comfort
At first glance, the Sennheiser HDB 630 may look familiar to fans of the brand’s popular MOMENTUM 4 series — and that’s intentional. Built on a similar chassis, the headphones feel perfected for long listening sessions with plush over-ear cushions and a headband wrapped in premium Japanese Protein Leatherette. This choice of materials ensures comfort even during extended use, whether you’re on a flight or working from home.
Audio Performance That Speaks for Itself
What sets the Sennheiser HDB 630 apart is the focus on true audiophile sound. Inside each earcup sits a 42 mm dynamic transducer crafted by Sennheiser’s own team, designed to deliver a neutral, balanced sound with rich mids, detailed highs, and controlled bass. Whether you enjoy acoustic music or complex studio mixes, these headphones make every detail come through clearly.
These headphones support up to 24-bit/96 kHz resolution for wired or Bluetooth listening, ensuring you hear more from every track. A USB Type-C connection or the included USB-C Bluetooth dongle enables high-quality aptX Adaptive streaming even on devices that don’t natively support it.

Custom Sound Control
The Sennheiser HDB 630 gives you powerful tools to shape your listening experience. Through the Smart Control Plus app, you can access a 5-band equaliser and a parametric equaliser that lets you adjust specific frequency ranges in detail. A unique Crossfeed feature gently blends channel output, creating a speaker-like soundstage that feels natural and spacious.
Noise Cancellation and Daily Use Features
Active noise cancellation on the HDB 630 adapts to your surroundings, letting you focus on music or podcasts without distraction. When you need to hear what’s around you, transparency mode brings external sound back in seamlessly. Voice calls are handled by integrated microphones that balance clarity with background suppression.
Battery life is generous, lasting up to 60 hours on a full charge, with a quick 10-minute boost giving several hours of listening in a pinch — ideal for travel or daily commutes.
