Our Take

HDB 630 is Sennheiser’s “do-it-all” wireless over-ear for people who care about fidelity first. The headline isn’t just ANC or battery life (though both are excellent)—it’s the way HDB 630 keeps your playback chain flexible: wired, wireless, USB-C, analog, and a dongle-assisted high-res path for devices that don’t natively support it.

High-Resolution, Anywhere

The HDB 630 can be used wired or wireless. Plug in via USB-C or a 3.5mm analog cable for a direct connection to your music library, including high-resolution content up to 24-bit / 96 kHz.

For untethered listening, Bluetooth 5.2 with aptX Adaptive helps prioritize sound quality and signal stability.

Included USB-C Transmitter Dongle

A standout value-add is the included USB-C Bluetooth transmitter, designed to bring a high-quality, low-friction wireless experience to more USB-C sources (phones, tablets, laptops). It’s an easy way to “upgrade” compatible devices into a more consistent wireless hi-res workflow—especially when codec support varies from device to device.

Have a Nice Flight

HDB 630’s sealed closed-back design and Adaptive Noise Cancellation reduce ambient noise for travel, work, and commuting. When you do need the outside world, Transparency and onboard mics keep things practical for quick conversations and calls.

Battery life is built for long-haul listening: up to 60 hours per charge, plus fast charging that delivers about 7 hours of playback from a 10-minute charge.

Brand New Tools in Smart Control Plus

The Smart Control Plus app adds serious sound shaping beyond basic presets. In addition to a traditional EQ, you get a Parametric EQ for more precise tuning (including bandwidth/Q and filter control), plus an A/B toggle for quick comparisons.

Inspired by Sennheiser’s flagship HE 1, Crossfeed gently blends channels for a more speaker-like presentation— especially helpful on hard-panned mixes that can feel fatiguing on headphones.

“The aim of this tuning was to let audiophiles on the move enjoy balanced sound with extended yet controlled bass. Whether plugging in or checking in, you always get a front-row seat to the emotional content in a recording, down to the last detail.”

— Tobias Ritter, Acoustic Engineer for HDB 630

Comfort & Build

Designed as a daily driver, the HDB 630 pairs a lightweight build with a soft-touch headband material for long-session comfort. Closed-back isolation also helps you keep volumes lower in noisy environments.
