Sennheiser’s next travel-friendly over-ears are built with one clear brief: sound first.
The company has announced the HDB 630, which boast a 42 mm dynamic driver with a fidelity-first tuning and the option to listen wired or over Bluetooth.
You get native playback up to 24-bit, 96 kHz over USB-C, aptX Adaptive for wireless, and a bundled USB-C transmitter for phones and tablets that do not support high-res codecs.
Battery life is quoted at up to 60 hours, with a quick top-up giving roughly seven more. The closed design teams with Adaptive Noise Cancellation to hush commutes and flight hum, while onboard mics handle calls and a quick transparency tap.
The fit borrows the comfy, travel-ready frame Sennheiser is known for, complete with a case and the usual cables, so you’re not fishing around for adapters.
The fun bit lies in the tuning tools. Inside the Smart Control Plus app you get a full parametric EQ with adjustable Q and filter types, plus an A/B switch to compare tweaks. There’s also Crossfeed if you want a more speaker-like feel on older, hard-panned mixes.
That’s a different pitch to crowd-pleasers like the warmer-leaning Momentum 4, and a different focus to the feature-rich Sony WH-1000XM5. The HDB 630 approach is simple enough as it lets you set the sound once and carry it with you across apps and inputs.

At £399.90, the HDB 630 sits right in premium ANC territory. You get proper battery life, solid isolation, and tools that nudge these more toward hi-fi habits than bass-boost fireworks. With USB-C audio on a laptop, aptX Adaptive on the move, and that little transmitter for the rest, the setup feels flexible without turning into homework.
This reads like Sennheiser giving travellers a serious listen without the faff. Long legs on the battery, a calm default tune, and grown-up EQ options make more sense than yet another set that just thumps harder.
