CMF Headphone Pro: two-minute review
Anyone familiar with Nothing and/or its affordable sub-brand CMF (often written as “CMF by Nothing”, but the company has seemingly dropped the last two words of its traditional moniker for this particular product) knows that a normal-looking set of headphones was never going to be on the brand’s bingo card.
And true to form, the CMF Headphone Pro neither look normal nor behave normally for the level – and I mean that in a good way. They’re modular, with the option of buying extra ear pads if you want an even more striking look (pistachio with orange, anyone?) and there are three thoroughly abnormal on-ear controls, too, including an ‘Energy Slider’, an excellent ‘Multi-function roller’ and an ‘Action button’. All of which I’ll get into later.
How’s the sound? Actually, really good for the level – easily as detailed, nuanced and energetic enough to skip to the top of our best cheap headphones guide. And while they won’t compete with the more flagship models in our best headphones roundup for neutrality or audiophile-grade insight (and the noise nixing won’t challenge pricier sets from Bose, Cambridge or Apple in our best noise-cancelling headphones list), there’s clarity, a great circumaural delivery, two types of spatial audio, LDAC and hi-res wired connectivity.
And all of this means I can’t – nay, won’t! – pick too much fault for the money, especially when I’ve compared them to Nothing’s original Headphone (1) and actually preferred the audio in the newer cans…
Oh, and that’s before I get granular on the fact that the CMF Headphone Pro include one of the most detailed hearing tests of any set of cans I’ve ever tried at the level, which the headphones use to create a remarkable personal profile for your listening. It’s something I thoroughly recommend you take soon after buying them.
OK, your EQ is limited to three tabs if you want to create a preset yourself, you don’t get a hard-shell case (or even a USB-C charger) in the box and the ‘Energy Slider’ feels a little surplus to requirements when they’re a bit bassy to begin with (although some will love it – particularly grime and drum ‘n’ bass fans). But the battery life is nothing short of excellent for the money and for me, the sound quality more than atones for these minor drawbacks.
All in all, you could do so much worse for $99 / £79 – and having seen a few healthy discounts already, I find myself recommending them even more urgently…
CMF Headphone Pro review: price & release date
- $99 / £79 / AU$179
- Launched on September 29, 2025
The CMF Headphone Pro launched on September 29, 2025, with a list price of $99 / £79 / AU$179, but in the UK I’ve already seen them discounted to £49 (at the time of writing, Black Friday approaches). This is huge because for that money you won’t regret this purchase, I assure you.
At their regular list price, the CMF Pro Headphone’s closest competition is likely the 2024 1More Sonoflow Pro HQ51 at $89 / £99 / AU$130, which also boast a great battery life and perhaps edge it for ANC efficacy, but the build is a tad flimsier, including the buttons. Also the 1More’s app is neither as seamless or enjoyable and to be honest, the design doesn’t exactly wow me – not like the CMF Headphone Pro’s does, anyway.
Meanwhile, Nothing’s own flagship Nothing Headphone (1) launched on July 15, 2025 with asking fees of $299 / £299 / AU$549 – ie. at least triple the price of the CMF Headphone Pro, depending on where you’re buying. So, you know, food for thought there…

CMF Headphone Pro review: features
- Excellent Personal Sound curation
- Class-leading battery life
- Premium-feel companion app
Here’s the thing with the CMF Headphone Pro: they surprise you at every turn. The Nothing X companion app is slick, chic and helpful. Make no mistake, the experience here is thoroughly Nothing, which is to say that it still feels premium, rather than budget-grade.
The excellent hearing test software – which takes roughly three minutes and involves struggling to listen to ever-quieter tones piped first into your left ear, then your right – creates a graph of your hearing in each ear, then one of the best Personal profiles I’ve had the pleasure of testing at this level.
Aside from support for the more hifalutin LDAC Bluetooth codec, the CMF Headphone Pro also offer wired 3.5mm Hi-Res certified listening, albeit only when they’re powered on, rather than passively. I hooked them up to my FiiO M15S (which is a fair bit smaller than the FiiO M23 player) and Teenage Fanclub’s Satan was every bit as jagged, petulant and angsty through the ragged intro as I could’ve wished for, even at 45 per cent volume.
There’s a dual connection toggle in the app which essentially means multipoint is on the menu and why you’d ever toggle it off I don’t know – it becomes essential very quickly for chopping and changing between music from my phone and team meetings on my laptop.
Also here in the Nothing X app, you’ll find noise cancellation in low, mid, high, adaptive and off increments, as well as a transparency option. The transparency profile in particular is very good, augmenting nearby voices in a useful way and without making frequencies within my music go tinny and unpleasant.
The ANC is fine rather than fantastic at dulling extraneous noise (the claim is up to 40 dB noise reduction, although that feels optimistic to me), but it does so without upsetting my music’s timbre and detail. Ultimately I’d rather have it than not, which is not something I say about all budget noise-nixing software and at this level that’s more than good enough. Serious, weapons-grade active noise cancellation really does still require climbing further up the food chain, because I’ve yet to find anything for this money that offers Bose-grade ANC. OK? OK, good to make that clear.
While I’m on the subject of mics (because these are imperative for the aforementioned ANC), the Headphone Pro come with three of the what Nothing calls “HD microphones” and with that same metallic wind-resistant mesh around each of them, they do look almost identical to those on the Nothing Headphone (1). Aside from ANC, these mics provide Clear Voice Technology in a bid to keep your voice sharp in calls. Now, I’ve been told my dulcet tones were indeed audible and clear in calls, but perhaps because the cups are quite big and the padding so ample, passive isolation is also good to the point that I could barely hear my own voice when talking. There’s no sidetone-adjacent tech to boost your own speech either. Would I expect that at this level? No, but it’s my job to point it out as a very minor issue.
Elsewhere, there are two flavors of device- and streaming service-agnostic spatial audio: cinema mode or concert mode. Cinema mode broadens the soundstage a touch, for clear dialog and decent pew-pew bullet effects in movies; concert mode is all about plonking you in the middle of a concert. Neither offers a dynamic, head-tracked presentation with your phone as the source device, mind, but I still enjoyed concert mode for lowering me into the melee a touch more.
CMF Headphone Pro review: sound quality
- Punchy, expressive and zealous – a true circumaural listen
- Nuance and detail with both wired and LDAC listening
- Limited in-app EQ options; energy slider gives mixed results
I’ll talk a lot about the energy slider to amp up the treble and bass in the ‘design’ section of this review, below (since this unusual button is a key part of the headphones’ design) but know this: if you want the most detailed, layered, unadulterated sound, you should probably leave this kind of tinkering alone.
There’s a low lag toggle in the app to minimize issues when watching content, but I keep that off to test the sound over LDAC. And here, Billie Eilish’s WILDFLOWER is emotive, textured, layered and underpinned by inky-deep and resonant keys.
Uh Oh by Tate McRae is a great test of the CMF Headphone Pro’s bass impact and, let me tell you, if you like to feel a beat in your molars, these headphones can oblige. It’s a head-nodding, cohesive mix with snap and crisp leading edges of notes, particularly through those zealous bass registers.
Switching to Girls Like You by Maroon 5 and I hear the intentional blurring of the axe in the intro, with Adam Levine’s vocal upfront, up-close and central in an expansive and exciting soundstage. It’s Amazing to Be Young by Fontaines D.C. is a similar story – and here I perceive treble elements in the intro that lesser headphones can’t reach, along with oft-overlooked happier inflections is Grian Chatten’s voice.
It’s an emotive mix overall, but Nothing has just about stayed on the right side of faithful here, rather than succumbing to parlor tricks to get you in the feels – unless you want to deploy those with the slider. Every Other Freckle by alt-J is a good one to to prove this. I really get the sense that Joe Newman wants every other freckle, even at 50 per cent volume, with certain lines (like ‘let me be the wallpaper that papers up your room’) jumping out more readily in what is a highly complex track.
Did I listen against the original Headphone (1)? I did. And while the presentation is a touch more neutral in the inaugural (and much more expensive) product, I did feel that the CMF opens the audio out just a touch more. It’s also a more full-throttle listen to boot.
Could the CMF Headphone Pro offer even more detail – even more nuance through the rise and fall of each musical passage? Yes, of course, but if the ultimate in audiophile sound quality had been achieved for this money we could all go home. There are compromises in terms of true neutrality and an ounce or two of clarity here and there over much pricier options. But know this: for the money, these headphones sound a lot better than I expected.
- Sound quality score: 4.5/5
CMF Headphone Pro review: design
- Nothing isn’t afraid to be different – but no cassettes on your ears here
- Extension arms are silent; comfort is good
- On-ear controls work well, but the Energy Slider is a tad gimmicky
If you’d asked me to sketch what I thought a set of headphones made by Nothing’s budget sub-brand CMF should look like, I can confidently tell you that I would not have drawn the CMF Headphone Pro.
Where the CMF Buds Pro 2 are all angular lines, slightly odd circle and grid motifs, brushed matte plastic (available in dark gray, blue, or red and with a silver rotary dial in the corner of the case), the CMF Headphone Pro come in totally different light green, light gray or darker gray glossy finishes with a resoundingly cushioned, polyurethane synthetic leather and memory foam build across the headband and ear pads.
My review sample is giving two tubs of pistachio ice cream and, for me, the build quality is rock solid for the level. The band is comfortable over the crown of my head, extends silently and offers decent clamping force without ever hurting. The ear cups are generously padded and rotate to lie flat (although they don’t concertina up into the band for easier storage) and the buttons are not at all flimsy.
So let’s explain what’s going on with those, shall we? On the left ear cup, in between two mics you’ll find power/pairing, your 3.5mm in and an ‘Energy Slider’. The function of this solid little slider can be switched between ‘Bass Tuning’ and ‘Treble Tuning’ in the Nothing X app.
I cue up Kehlani’s Folded to toy with the bass slider and ramping things up does augment the low end, albeit to the point of marginal bloating – but hey, it’s a way of replicating that authentic ‘standing just a little too close to a big (possibly blown?) sub at a gig’ feel. Switching to the treble option and the track does sound a little too sweet and even tinny when moving the slider through its range, but then I know from various hearing tests that my own ear hones in on treble frequencies in most mixes. Having been on the fence about all of this for a week or so, I’ve decided that it does add novelty and for some grime tracks it might be a winner.
On the right ear cup and above the USB-C port, there’s a little circular button with a red dot at the center. In the X app, this is simply called ‘Button’ and your options here are a single press or long press. A single press can handle voice assistant access, noise control, spatial audio profiles or even switch the mics on or off (there’s another on this ear cup). A long press? That can perform any function from this same menu.
But above this is where I think Nothing has really knocked it out the park, because this brings me to the ‘Roller’ in the controls menu. And as well as being able to roll this to quickly tweak the volume (seems like a small thing but really isn’t – especially when you’re on the go) you can press and hold it to scroll through noise-cancellation profiles, single press it to pause and resume playback or answer/hang up on calls, double press to skip a track or triple press to go back.
There’s no IP rating for rain or dust ingress, which isn’t unusual at the level (or even a rung higher up) but because you also only get a simple fabric bag for transportation, you might want to think carefully about taking these out in the rain.
One other thing: you get a 3.5mm cable in the box, but no USB-C charger cable – much less an actual wall plug for it. In 2025, you almost certainly have one of these already in the wings, waiting for the job, but if you were hoping for an extra (or one in the CMF Headphone Pro’s winsome pistachio green, say), you’ll be disappointed.
CMF Headphone Pro review: value
- An excellent all-round budget package
- No charger or hard-shell case – but these are minor omissions
- As a sound-per-pound proposition, there’s top value here
I mean look, for this money I struggle to argue with even basic headphones, provided they sound good for the level. But the CMF Headphone Pro are not basic headphones – just see the hearing test software and extra on-ear controls for that. They’re a lot better than basic and a lot better than their fee suggests.
Market saturation does of course drive pricing and here, that’s very good for us.
OK, those wanting bubble-of-silence ANC will not find their ideal set of cheap headphones here (the ANC is adequate, it just isn’t shutting out the entire world), but those wanting zealous, bass-blasting sound and/or a quirky design that actually is not a case of style over substance just found a great inexpensive option to step out with.
Should I buy the CMF Headphone Pro?

CMF Headphone Pro review: How I tested
- Tested for four weeks
- Used at home, on the Eurostar to Paris, at the (blustery) beach
- Predominantly tested using Tidal and Apple Music, or wired to my FiiO DAP
I tested the CMF Headphone Pro over a period of four weeks, using my MacBook Pro, iPhone 15 Pro Max and LDAC-toting FiiO M15S as source devices.
I listened to everything from my heavy rotation Three Bean Salad podcast on a long walk on Weymouth’s blustery beach, to Bruce Springsteen’s Nebraska ’82 Outtakes on the Eurostar train to Paris from London. I listened in both wired and wireless modes and found much to celebrate in terms of audio chops across the frequencies and energy.
I maxed out the battery and got 49.5 hours from them using ANC too – which, given their 50-hour claim at 50 per cent volume is no meat feat.
I’ve been testing audio products full time since 2019, first on TechRadar’s sister publication What Hi-Fi? as a lowly Staff Writer, then Senior Staff Writer at TechRadar and, since early 2024, Audio Editor (hey, career progression is gradual sometimes in journalism… and that’s fine when you’ve got music).
