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.

"The HDB 630 accuracy is amazing. These are true reference headphones even as wireless. As advertised, they represent music as it is presented by the source, without manipulating it. That's just what I was after. The soundstage is wide, with a great balance in neutral setting between bass, mids, and highs. Plus, one does have the option of manipulating the music presentation in the settings if so desired. HeadAmp was excellent, with great prices, quick shipping, and status updates."

Well balanced and Good for longtime listening
"With a help from HeadAmp, I got a chance to preorder 630, it turned out be a right decision for me. They have high resolution to distinguish instruments and voices from music and the sound was well balanced over the wide range of spectrum. You can easily listen for a long time without fatigue in your ears. Only downside I found was when I have two connections with the phones, it was not smooth to add 3rd one and kick out one of the two previous connections. I kind of had to delete one of the previous connections. I might not be familiar with app controls. Still wired headphones sound quality is better but I can recommend this for casual listening or traveling. Noise cancelling was good enough to block out airplane noise during the last trip of mine. I highly recommend this headphones."
— Soo M. (5/5)
