Sennheiser has launched the HDB 630 wireless headphones in India, following their US release last month. The company says the HDB 630 is made for listeners who want strong audio performance with both wired and wireless flexibility. The design comes from the Momentum 4 but adds a customized acoustic system for focused listening.
The headphones use a 42 mm dynamic transducer built at Sennheiser’s Tullamore facility in Ireland. It is supported by several acoustic treatments that aim to deliver clean mids, clear vocals, and fast dynamics. The company says the sound stays close to what is heard in the mastering studio.
The HDB 630 works with wired and wireless high-resolution audio. Through the USB Type C port or the supplied analog cable, listeners can play music at up to 24 bit and 96 kHz. Wireless use is supported by Bluetooth 5.2 with aptX Adaptive. This is meant to offer stable streaming and better sound quality. Sennheiser also includes a USB Type C transmitter dongle. This gives high-resolution aptX Adaptive support to devices that do not support it natively. Only about 16 percent of current smartphones support this codec, and the dongle raises compatibility to about 80 percent.
The headphones introduce new sound tuning tools through the Smart Control Plus app. Crossfeed, inspired by the HE 1, blends left and right signals to create a more speaker-like experience. A new Parametric Equalizer gives control over individual frequencies with adjustable bandwidth, filter types, and an A and B comparison toggle. These settings are processed on the headphones themselves, so the sound remains the same across apps and devices. Users can also share presets. A future update will add QR code preset sharing. The app also lets users adjust noise cancellation, on-head detection, and codec selection.

The Sennheiser HDB 630 costs Rs. 54,990 in India. It can be pre-booked for Rs. 44,990, and customers will get an Accentum Open TWS headset worth Rs. 12,990 at no extra cost.

In the US, the headphones are priced at 499.95 dollars.
