Flawless sound, no wires, and a battery that lasts for up to 60 hours. The Sennheiser HDB 630 lets you take true audiophile sound anywhere you go.

Precision engineering brings out breathtaking clarity, a neutral tone, detailed mids, and a wide soundstage. Use aptX™ HD and aptX™ Adaptive Bluetooth® codecs from a high-resolution source such as Sennheiser’s BTD 700 Bluetooth® USB C Dongle or plug in via USB C for pure fidelity.

The advanced parametric EQ lets you define frequency bands and filters as you please. Crossfeed function balances classic tracks for better headphone listening while Active Noise Cancellation eliminates background noise while maintaining high-end audio quality.

• Audiophile tuning: Sennheiser’s in-house 42 mm transducer and refined acoustic design deliver a neutral audiophile sound with lifelike mids, stunning detail, and a wide, natural soundstage.
• High-resolution audio: Enjoy high-resolution wireless sound with support for aptX™ HD and aptX™ Adaptive, especially when paired with the included BTD 700 Bluetooth® USB C Dongle. For maximum purity, connect via USB C cable or analog input for lossless listening up to 24-bit/96 kHz.
• Parametric EQ: Expert-level equalization lets you define frequency bands, bandwidths, and filters to precisely shape your sound. Tailor bass, enhance vocals, or fine-tune for any genre.
• Crossfeed feature: Designed for classic tracks with hard-panned mixes, it takes instruments concentrated on one channel and balances them out, providing a more natural listening experience, similar to how the track would sound on your stereo system.
• Hybrid adaptive ANC: The powerful noise cancellation combines feed forward and feed backward ANC technology to block distractions without degrading clarity, dynamics, or balance. The adaptive mode automatically adjusts to the environment for optimal performance.
• Adjustable transparency mode: Low-noise microphones allow you to instantly hear surrounding sounds for improved situational awareness when you need to stay aware of your environment.
• Up to 60-hour battery: A class-leading battery lets you listen for days, not hours and keeps you going through long trips or work weeks. Just 10 minutes of fast charging adds up to 7 hours of playtime, ideal for when you’re on the move.
• Refined acoustic architecture: Every part of the acoustic chain, from the transducer to the transparent acoustic mesh, and optimized back volume, works in harmony to produce smooth upper mids, detailed treble, and an open, and natural soundstage.
• Exceptional comfort: A lightweight build, low clamping force, generous earcups, and a premium Japanese leatherette headband ensure hours of fatigue-free listening.
• BTD 700 Bluetooth® USB C Dongle: The USB C dongle delivers high-definition audio for music lovers and gamers. Enjoy easy plug-and-play setup for seamless, reliable connectivity and versatile compatibility.
