Looks like Nothing’s push into over-ear headhphones is trickling down into its cheaper subbrand, CMF. According to a few official teases on X, CMF is gearing up to launch the Headphone Pro, which would be its first-ever pair of over-ear headphones. As per usual, CMF is promising a few flourishes that could make its headphones just a little different than your run-of-the-mill budget audio device. I have to say, I like the direction CMF appears to be headed.

Firstly, there’s a hard release (or unveiling) date of Sept. 29, so we’ll know the answers to all this stuff before the end of the month. As long as we’re in the speculative stage, though, CMF gave us a few things to chew on. The most intriguing to me personally is the “remix everything” tease that shows the earcup on the Headphone Pro being screwed in and replaced by one with a different color—a nice, bright orange that the company has made a part of their design language with phones and earbuds.
Replacing earcups isn’t groundbreaking, but if CMF’s prior interest in modularity is any indication, they may have more to announce on that front than just earcups. In CMF’s phones, for example, prior generations allowed users to replace the backplate and also add on accessories, including camera attachments, lanyards, and a “universal cover.”
Meet the energy slider. What do you think it does? Headphone Pro. 29 September. pic.twitter.com/mfxjh2mJ7r — CMF by Nothing (@cmfbynothing) September 22, 2025
On top of modularity, CMF is also teasing an “energy slider.” I’m less positive about what that means, but speculation seems to be keyed in on a few possible things. One idea that I actually would find useful is using the button as a way to adjust bass levels in a more fine-tuned way. As someone who actually doesn’t love a ton of bass all the time, being able to use a slider to tweak bass levels on the fly sounds pretty useful. It’s also a lot more granular than having a “bass boost” button or something to that effect that can only be toggled on or off.
Either way, we should have answers to those questions soon, and also answers to more important questions like how the Headphone Pro compare to Nothing’s $299 Headphone 1. Even if there is a big sound or active noise cancellation difference, I’m at least grateful that both pairs seem to be embracing buttons big time.
