You can pre-book them now at a special price of ₹44,990, while the regular price is ₹54,990. They also give a free pair of Accentum Open earbuds worth ₹12,990 as a limited-time gift with pre-booking.
The HDB 630 comes with a special USB-C Bluetooth dongle named BTD 700. This dongle helps send high-resolution audio over wireless connections. With the dongle or wired USB-C or 3.5mm cables, it plays up to 24-bit/96 kHz hi-res sound. This lets you stream better quality files and codecs even on devices that do not support them normally.

A key feature is the new Parametric Equaliser in the app. It lets you control each frequency band exactly, not just basic bass, mid, or treble. There is also a Crossfeed mode that makes stereo sound feel like speakers. You tune both in the Sennheiser Smart Control app. It has adaptive noise cancellation to block noise and a transparency mode to hear surroundings.

Sennheiser used a new transducer design for clear mids and high treble. The sound is neutral and accurate, not bass-heavy for fun. It builds on the Momentum 4 body but with better acoustics. It offers comfort like replaceable earpads and a strong carrying case.
Battery lasts up to 60 hours on one charge. A quick 10-minute charge gives about seven hours of playtime. Good for long trips or daily use. It includes the BTD 700 dongle, cables, accessories, and a two-year warranty.

In India, pre-book until December 4 on Sennheiser’s store and partners like Headphone Zone, Audio Store, Concept Kart, and Amazon India. It suits audiophiles and pros who want high fidelity, customization, and hi-res support.
The high price fits serious users, not casual ones seeking bass or cheap ANC. If buying, check if your devices use the BTD 700 dongle well and if neutral sound matches your taste. For tunable, detailed wireless sound and long battery, it is a top choice in Sennheiser’s range.
