CMF BY NOTHING Buds 2a Wireless Earbuds 2025 New Active Noise Cancelling 42dB Hybrid ANC Bluetooth Headphones, 12.4mm Dynamic Driver for Big Bass, 4Mics Clear Calls, Sport Ear Buds for iPhone Android

Should you buy these? Yes. First of all, these are an incredible value, even though I'm not sure what the actual price is. I bought a pair today for $30, curious about how well these perform despite being so cheap, considering how well-liked they are. I tested them on a set of tracks that are unbalanced, each in their own way (e.g. too heavy on the bass/treble/etc.) and somehow they all sounded good. I don't know how that's even possible. These little things have bass you can feel, which I've never experienced with any kind of earbud. It's not something that I particularly enjoy, but a lot of people will, and it's impressive nevertheless. When I like a pair of headphones I get a backup pair, so I just bought another pair of these and they were only $20. After I bought them they went up to $40. All of those prices are justifiable for the quality these provide, but I am very confused why the price keeps changing on me. But let's say they're supposed to be $40. At that price point, you wouldn't think to compare them to Sony's WF-1000XM4 or Apple's Airpods Pro 2, but they sound better than both. It's not that hard to sound better than Airpods, but there are other features worth comparing. Sounding better than Sony's WF-1000XM4s, however—at somewhere between 6.75% and 13.5% of the cost—is pretty incredible. Granted, they're definitely not more realistic, but these somehow manage to make everything sound good. Senheiser's IE 600s are for realism, but I would not argue that they sound better. When you're listening for fun, the CMF Buds 2a are the most fun. Normally, I prefer uncolored, realistic sound even in a headphone I use for fun, but these are a rare exception. I love trying new headphones because you get to hear your favorite music in a new way. Sometimes it's not a huge difference, but I hear more detail than average so I enjoy the subtle stuff. I think the sound stage of these buds elevate the sound significantly. You can really hear the details, even in a bad mix. You can hear the sound move so well and with such fluidity. It's just hard to believe these are $20-40 Bluetooth headphones. I've used these for only a couple of hours now, so I can't speak to battery life, but I'm hoping they truly will make it through the workday. They're surprisingly comfortable, and the medium tips actually fit great (usually I'm a small size). I like the design. Everything's plastic—and not plastic that feels particularly sturdy—but the design is nice. While the headphones feel like they go into the case backwards (to me, at least), they snap in thanks to magnets and look nicer in that "backwards" position. The case is very small and looks nice in a minimal way. The active noise canceling is good and comparable to the WF-1000XM4s. I think the AirPods Pro 2 win in the ANC category by a hair. If there's one place I can fault these buds is in the touch controls. I can turn ANC on and off, but so far I haven't been sucessful with any other option. They just don't seem to respond well to taps. I don't really care, though. I find touch controls useful only when I can't control the volume and track through any other mechanism. I find it much easier to make these adjustments on my phone or computer. Still, I would prefer if I could get the touch controls to actually work. These buds are my new recommendation for non-audiophiles, and audiophiles who want a fun pair. They're exceptional for the price, and would still be competitive at five times the cost. I'm really glad I decided to give these a try.

I bought these because my left Nothing Ear (a) fell into the ocean. I really liked those. I've lost a lot of earbuds recently and it's hurting my wallet just a little bit so i decided to be cheap this time. I saw these for $25 and just bought them because my Ear(a) were so good. I'm glad I did. These are great. ANC is good if you pick the right tips. I usually use the medium tips on all my buds but these required the large ones to make a nice seal. They are comfortable and light if you find a tip that fits you properly. Transparency is noisey but works. ANC performs close to my Nothings but not the transparency. Music is OK on these. It's just as good as some earbuds that i have paid more for but my Nothings smoke these. That's to be expected at less than half the price. They do get quite loud and the bass is OK. Not disappointing which is all i was looking for in this price range. The controls are limited but work well. I wish i could customize them as much as my Nothings considering they use the same app. The case doubles as a phone stand which has already come in handy. I wish the spinny lanyard thing was a volume knob. These are an absolute steal at $25. Nothing makes good earbuds. Maybe if I dont lose these for long enough I'll treat myself to the Nothing Ear (3).

For the price, these are actually really good earbuds. The noise cancelling is decent, but definitely not amazing. It takes the edge off background noise and does a respectable job for everyday use, but the advertised 42dB shouldn’t have you expecting to enter a magical cone of silence. People, traffic, and the general chaos of civilization can still find you. Sound quality is surprisingly good for the price, though. Nice bass, clear enough audio, comfortable to wear, and I actually really like the orange color. If top-tier ANC is your priority, spend considerably more money. If you just want a solid pair of inexpensive wireless earbuds with good sound and useful noise cancelling, these are a great value.

The CMF Buds 2a are some of the best wireless earbuds I have purchased so far. They deliver excellent sound quality, a clear microphone for calls and video conferences, and a comfortable, secure fit. One of my favorite features is the ability to connect the earbuds to two devices, making it easy to switch between my phone and computer. They work very well for phone calls, music, videos, and online meetings. Overall, these earbuds provide excellent performance and value. I highly recommend them to anyone looking for reliable, comfortable wireless earbuds for everyday use.

I bought it on Black Friday for $20. I was not expecting much, was getting them for phone calls. Oh boy... these really caught me off-guard, they are actually very good! I have only used them as of this review less than one day, but I have been trying to make them sound as good as the BOSE QC35ii headphones I have (BOSE sound is in another league). Equalizer/Sound:Recommended Equalizer settings on Nothing app: BASS: +6 MID: +1 TREBLE: 0 Ultra Bass: Level 5 For rock, these settings are the best you can probably get (of course they still sound fantastic outside of rock). I tested these for live-streams (gaming/shooting) and voices sounded normal-good (compared to my headphones), normal songs sounded good, instrumental music (from Elden Ring) sounded very good, rock (I tested Abracadavre, a song from Call of Duty: Black Ops 1) and at around second ~0:20 where the good part starts, sounded somehow disappointing *with the default Dirac equalizer setting*, but once I tested the customized equalizer I just showed earlier it sounded MUCH better (still not even close to the BOSE headphones, but they do sound from acceptable to good now). If you combine these settings with a separate equalizer app, you can probably make these sound much better. The ANC (Active Noise Cancelling) is, like mentioned in Linus Tech Tips, pretty decent-good, it is like 1/3 the strength of the BOSE headphones (ANC from CMF does not hurt the 1st time you use it, I recall the 1st time I used the BOSE ANC that I felt being inside a submarine very deep in the ocean). Microphones during calls: sounds very clear (in a room with metal fans that make strong white noise). I tested by calling myself to another phone. Case: It fits extremely tight on the small pockets that jeans have. So far has done it's job of charging, but since this is day 1 I will not talk about this aside of saying it works. Connection: Tested on an Asus Zephyrus G15 GA503QR (Linux Pop-OS), Xiaomi Redmi Note 11 and Google Pixel 6. In all it connects fast and stable. Sometimes increasing the volume increases more loudly one bud first but then the other bud catches up, but normally they both do it at the same time. Audio to video latency, okay-good. When I start a YouTube video the audio kicks in at like second 1-2, but after that no noticeably latency (very slight latency whenever I saw someone in a video game shoot, the sound and visual recoil of gun did not match, maybe 0.2-0.4 ms latency guesstimating by eye). Ear tip fit: pretty good, I recommend trying the large one for a better seal, so the ANC is better (not by that much). Does it fit: Yes, it does not fall off at all, can sleep while wearing them comfortably (sleeping on the side). Is this worth it? Yes (in my case, for $20 this was a steal), but I will suggest looking the Plus version of these earbuds since (I believe, please check first) the equalizer settings on the Nothing app for that earbud is much more detailed and advanced, also you can modify how strong you want the ANC to be (and has like personalized audio, whatever that means). The CMF Buds 2 Plus is $80 and CMF Buds 2A $50, so if you see the Plus in discount closer to $50 I suggest you get those; otherwise Buds 2A for less than $30 is very good deal (both are reviewed in Short Circuit channel on YouTube). Pretty satisfied. Updated 12/7/25: 1. Bluetooth range: Much better than my Bose, very surprised. 2. Battery life is very good, was in a call for like 2 hours and still had like 65% I believe. 3. This supports the feature that Airpods have of "seamlessly" connecting between multiple devices and switching fast (I have not tried it, but you need the Nothing app to enable it. Annoyances: 1. No way to disable hang up calls and other call specific touch gestures. I accidentally hung up a call trying to adjust my buds. 2. The touch sensor is VERY sensitive, and... essentially the WHOLE stick of the bud is detected by the sensors, so just adjusting them at the tip (the opposite side of the sensor's location) will still hang up the call, so be careful. 3. If bud slides off your ear, use a smaller size. For me small size prevents them from falling off. So far very good and solid performance.

Honestly if it weren't for all the marketing BS, this would have been a 5 star review, plain and simple: this are awesome for the price, this tend towards the bass side, it can be better with an EQ adjustment but will always lean towards the bass, the ANC is just bad, honestly don't buy them for that, the mic is usable, always keep in mind the price, for that price this is an amazing product, just go with the right expectations, this are not audio file type headphones. Update: there is a massive issue with the ANC, it enables itself constantly... At first I thought it was me touching the headphones but I disabled the option for that in the app... It keeps happening, this is honestly a big issue, I am thinking about returning them now, the issue could be potentially dangerous when you are walking outside or worst if running, I always set it to OFF, as it is really not good and is distracting the ANC, but no matter what I do it keeps coming back on, on its own, it can be disorienting and make you feel nauseated, specially if you are walking or moving in any way with just one of the buds on you, as it leaves you half deaf, you may loose balance and fall if you don't pay attention and notice that something is wrong and it could make you feel uncertainty about your own hearing, like if you were loosing it, because again, the ANC is bad it doesn't filter all the outside sounds, so you still hear things, you just hear them a bit less, honestly if it keeps enabling itself I may have to return them, I already issued some sort of help ticket on the app, we'll see what happens. Update: CMF has not responded to my ticket, it seems the issue could be related to the mobile app, I tested them with another phone without the app installed and the issue was did not repeat, I just uninstalled the app on my phone (which is kind of dumb, because I like to control the EQ manually to help the sound quality) and I will be testing over the next couple of days, I am still leaning towards returning them, specially if there is no response from CMF, I honestly would love to have a kill switch and just completely disable the garbage ANC forever Update: uninstalling the app helped but the issue persist, it enables itself, the good thing is that now happens like once or twice a day, not like before which was like every 30 seconds, still don't like that I basically loose complete control as I can't use the app, but it's definitely better this way, still no communication from CMF, I honestly like the headphones, specially for the price but I am still leaning towards returning them, what if the issue gets worse? And what if that happens after the return window closes? Not a fan of the lack of communication, specially seeing that there are more reviews here commenting similar issues, reviews from many months ago... Which indicates that there is no interest on fixing the issue... Which is really sad, they damaged their own product for the sake of.....? What? Marketing? Just to be able to say "we have ANC"? Sad... Last update: CMF never answer, I downloaded the app and it seems like the issue is fixed, I am going to keep them, but I am also going to leave the 1 star review, I would leave 0 stars if possible, honestly this are really good for the money but it almost feels like the marketing was designed to shoot themselves on the feet and they definitely manage to do it multiple times.... sad, if you are planning on buying these remember to disable the ANC and disable the touch setting on the buds that enables them immediately, that would save you a lot of "what is happening?" moments, also I would recommend using a custom EQ and fine tune them removing as much bass as you feel comfortable with, it would make a huge difference, you will go from just hearing the bass of every song to actually being able to hear the song, the vocals and all of the other instruments!

Having used the new CMF Buds 2a for a couple of weeks, I am genuinely impressed with the value CMF has packed into this 2025 model. The headline feature, the 42dB Hybrid Active Noise Cancelling, is the real star of the show. It performs well above its price point, effectively silencing the low-frequency drone of my daily bus commute and the distracting hum of the office air conditioner. The sound profile is also quite pleasing for general listening; the bass is present and punchy without being muddy, and the mids are clear, making podcasts and vocals come through crisply. The connection has been rock-solid, and I've experienced zero dropouts when walking through busy city streets. The unique CMF design aesthetic is also here, and they look far more premium than they cost.However, these earbuds are not without their trade-offs. While the ANC is fantastic with constant, low-frequency sounds, it struggles a bit more with sharper, unpredictable noises like nearby conversations or a dog barking. It dampens them, but they definitely still cut through. The call quality is another area where you feel the budget-friendly nature of the buds. In a quiet room, my voice comes through perfectly clear, but the microphones have a tough time isolating my voice from background noise when I'm on a windy street or in a bustling coffee shop. Furthermore, while the fit is comfortable for hours of listening, they don't feel quite secure enough for high-impact exercise; I wouldn't trust them to stay put during a run.Ultimately, the CMF Buds 2a are an easy recommendation for a huge number of people. The battery life is more than enough to get through a full day of heavy use, and the case provides several extra charges. Features like in-ear detection and customizable controls through the app are excellent quality-of-life additions that you don't always see at this price. If you are a daily commuter, a student, or an office worker looking for excellent noise cancellation and great sound without breaking the bank, these are an absolute win. If you're an audiophile seeking perfect sound reproduction or someone who makes frequent calls in noisy environments, you may want to look at a more premium option. For everyone else, this is one of the best feature-per-dollar deals on the market right now.

My first purchase from this brand. But im really happy with them so far. I haven’t even charged them since I got them. I think they were at 85% when I received them. So battery life seems to be decent! The sound quality is really good. Ill say good enough for the purpose in which i use them. I use earbuds in particular to listen to audiobooks at work. Yes music too, but i have over the ear headphone for the gym and travel. So buds are like daily on the go for me and discreet listening at work. It connects almost instantly to my iPhone every time which i love. And yes, you can change the touch controls in the app; along with sound quality stuff lol. I do like the fit in my ear, comes with other tip sizes ofc. Again, I’m glad I made this purchase because I only paid $30 for them and I unfortunately tend to lose my earbuds twice a year it seems. So I appreciate when I can find affordable quality buds. Only thing to note right now is that on the Buds2a- the dial on the case does nothing. I didnt know that… i thought it was going to control volume like the other models i looked at. I cant seem to find a way to make it control anything so yea…. Second, minor detail almost unnecessary to mention… but changing the ear tip took a lot more work than other earbuds I’ve had. Lol Update: my first time really needing noise cancelation and they work pretty darn well for the price i payed. Im sorry but i love these so much more than the JbLs ive been committed to. And battery life is pretty good. I wear them all day at work. Maybe like two days in a row before i instinctually charge them. Oh and I like how i can just press and hold to change ambience sound. Only con ive found with these atp is they dont give you that much of a warning before they die.

These have been awesome. Good noise cancelling. I've been using them for months now, never an issue.

Fantastic sound quality for the price. These are definitely the go to in ears for less than $100.

de los mejores in ear que he tenido la cancelacion de ruido me ayuda a concentrarme en clases y se han caido 1 vez en lodo y otra ve en agua y siguen como si nada la verdad me gustaron mucho y la aplicacion no me gusto el ecualizador pero bueno la verdad son muy buenos profe :)

作業しながらYouTubeをラジオ代わりに聴くのに音質はともかく安いのと思い購入。 aviotのTE-W1とかミドルクラスのイヤフォンなど複数所持しているがそこまで音質に差が無いので良い意味で驚き。 ノイキャンや外音取り込みはおまけ程度でそこまで効き目は良く無いがこの価格帯なら充分です。 アプリもそこそこ優秀で使いやすいのも高評価。 購入検討している方がいるのなら間違い無くオススメです。 高価なワイヤレスイヤホンは扱いが丁寧になり過ぎて使い辛い側面もありますので普段使いに最適な機種だと思います。

Dont really like the voice quality
