Descriptions:

> The in-house 42 mm transducer delivers neutral sound with lifelike mids, stunning detail, and a wide soundstage.

> Enjoy high resolution with support for aptX™ HD and aptX™ Adaptive, especially when paired with the included BTD 700 Bluetooth® USB C Dongle.

> For the purest signal, connect via USB C or analog input for lossless listening at up to 24 bit/96 kHz.

> Parametric equalizer for advanced equalization and the crossfeed feature give you complete control of your sound.

> Powerful adaptive noise cancellation blocks distractions without degrading clarity, dynamics, or balance.

> Listen for days, not hours, with up to 60 hours of battery operation.

> Why the HDB 630 sounds exquisitely neutral:
> The HDB 630’s tuning is all about balance: Fast and extended bass, clear lifelike mids, and controlled treble that keeps the music feeling open and natural.

> The HDB 630’s curve compared to the MOMENTUM 4 shows how audiophile tuning changes the listening experience.

> Notice the low end: The HDB 630’s sub-bass and mid-bass are quick and controlled, staying closer to neutral. This reduces any “masking” effects that can hide vocal detail. Moving into the lower mids, the HDB 630 remains smooth and even, keeping voices present and lifelike.

> In the upper mids, there’s a tasteful lift that gives vocals a richer, more intimate presence, balanced by a still-neutral bass foundation. The treble region keeps that balance, adding a sense of air without harshness — something you can see in the rise before 10 kHz, which helps improve the perception of a natural, open space around instruments.

> The result is a frequency response tuned for speed and clarity in the bass, lifelike mids, and controlled treble — all without the peaks or dips that can cause listening fatigue. It’s a more neutral, refined take on Sennheiser’s wireless sound that makes long sessions and critical listening a unique pleasure.
