- Sennheiser HDB 630 is released on October 21, 2025

- Sennheiser’s BTD 700 transmitter will be included, opening access to ‘hi-res’ audio to Android and iPhone users
Sennheiser has revealed his latest pair of wireless headphones intended to deliver “True Audiophile Sound” and is its first headphones as part of its HD-reference quality Audio Ragge. Sennheiser HDB 630 is ready to arrive on October 21, 2025 and is said to deliver “hi-res” audio, “extra long battery life” and active noise cancellation.
These wireless headphones put you back $ 499 / £ 399 / AU $ 999, which means they have to fight some of the best headphones around-sighted Sony WH-1000XM6 or Bowers & Wilkins PX7 S3.
So what does HDB 630 offer to make them stand out? Here’s all you need to know about them.
Hi-res sound anytime and wherever
The most important thing that Sennheiser wants to emphasize over his new cans is their ability to offer higher resolution sound without the need for wires.
That’s because the HDB 630 is assembled with Sennheiser’s BTD 700 USB-C Dongle, which can bypass the wireless transmitter used by your phone to activate APTX, APTX HD and APTX ADAPTIVE AUDIO.
Essentially, this means you can listen to your favorite tunes in higher than CD quality 24-bit / 96 kHz. It is more detailed than you can access, even with Spotify’s new loss -free update, but if you, for example. Enrolled in Tidal or Qobuz, you will be able to get a more revealing Bluetooth Lyte experience.
Of course, APTX still can’t handle the absolute best quality out there without any loss of fine details, but the inclusion of the dongle means that both Android and iPhone users will access APTX sound -especially some iPhone users have never enjoyed.
In addition, you can connect the headphones to your listening device via USB-C or an analog input for cable listening.
I’ve been using the headphones for about a week or so now, and I share my thoughts on the sound profile, attention to details and general Sonic capabilities in the HDB 630 soon-but I have been impressed with them so far, and they have definitely got some unique features that I haven’t seen from top-tier rivals.
Plenty to sink your teeth in
These headphones are not all about hi-res sound that is a lot more to explore.
Something that instantly got my interest is the inclusion of parametric EM. This allows a user to have full control over the specific frequency they want to change, with options for gain and Q-factor. This means that if you have a very accurate sound in mind, you must be able to tailor the headphones to your specific taste.
Another nice inclusion is crossfeed-something I have not personally used on a rival couple of the best over-ear headphones.
This mixes left and right audio channels, which can be useful if a recording has extreme channel separation – says if most of the base only plays from the right. By using crossfeed, traces like this can be optimized for listening headphones with a more balanced presentation.
On top of these inclusions, the HDB 630 will offer adaptive noise cancellation, touch checks and up to 60 hours of battery life with the ANC-the same as the five-star Sennheiser Momentum 4 wireless.
The new cans are available for ordering today (October 8) and will be fully released on October 21st.
