HDB 630 launched with new audio technology for precise tuning

HDB 630 launched as Sennheiser’s newest addition to its premium wireless headphone lineup in India, bringing a strong focus on sound accuracy and custom control. The company has positioned the model as a high-end option for users who want expert-level sound adjustments without needing studio equipment. The headphones arrive with the BTD 700 Hi-Res Bluetooth dongle, which expands compatibility and ensures lossless audio streaming across more devices. This release also marks the first time Sennheiser has added a Parametric Equaliser to a wireless headphone, allowing detailed control over individual frequencies.

The launch reflects Sennheiser’s growing attention to India’s premium audio market, where users look for balanced sound, long battery life, and advanced tuning features. With the HDB 630, the brand is aiming to combine studio-like accuracy with consumer-friendly wireless performance. Sennheiser states that the new model uses an improved transducer design with better magnet structure and airflow, giving clearer mids and extended treble.

The BTD 700 Hi-Res Bluetooth dongle is included inside the box, giving users access to high-quality audio even on devices that do not support advanced wireless codecs. Sennheiser claims that device compatibility improves from around 16% to over 80% when the dongle is used.

HDB 630 launched with specifications focused on sound accuracy

The HDB 630 launched with a design based on Sennheiser’s Momentum 4 chassis but includes several internal changes meant to improve precision and clarity. The headphones feature adaptive noise cancellation and support high-resolution audio playback up to 24-bit/96 kHz through both USB-C and Bluetooth.

A major highlight is the new Parametric Equaliser, which allows users to fine-tune specific frequencies rather than relying on preset sound profiles. This system gives more control to users who want a neutral, balanced output. The model also includes a Crossfeed mode that subtly blends left and right channels to create a more natural listening experience, especially for long sessions.

Sennheiser says the improved transducer structure helps maintain midrange clarity while supporting extended treble. The tuning is meant to stay neutral so that vocals and instruments remain clear without strong colouring.

Battery life has also been emphasized. The HDB 630 is rated for up to 60 hours of use on a full charge. A 10-minute quick charge can deliver up to seven hours of playback, which makes it practical for travel or long workdays. The headphones also come with replaceable earpads and a two-year warranty.

HDB 630 launched as a premium option for long-term use

With the HDB 630 launched, Sennheiser is targeting users who want long-lasting comfort, detailed sound control, and improved wireless performance. The new dongle offers stability and broader support across laptops, phones, and audio devices, reducing connection issues many users face with high-end wireless headphones.

The replaceable ear cushions extend the product’s lifespan, while the neutral sound signature appeals to listeners who prefer accuracy over heavy bass or boosted highs. The long battery life further positions the HDB 630 as a dependable daily-use headphone for work, travel, and entertainment.

Conclusion

The HDB 630 launched as Sennheiser’s most precision-focused wireless headphone yet, combining powerful tuning tools, strong battery life, and wider device compatibility. With the bundled dongle and launch offer, the model aims to deliver high-quality audio for users who want more control and long-term durability.
