CMF Buds 2a Wireless Earbuds Active Noise Cancelling 42dB Hybrid ANC Bluetooth Headphones, 12.4mm Dynamic Driver for Big Bass, 4 Mic Clear Calls, Sport Ear Buds for iPhone, Android, Dark Grey

+ : subtle noise cancellation, additional earbud sizes, quick connection, comfortable fit, long battery life, holes for keychain strap, fast charging, noise signals- : not completely noise cancelling, light plasticky caseI'm sure if you look at any of the other reviews under this item you can already tell this is a no-brainer. For the price, the earbud performance quality is pretty on par with any other competition but for 90% less for the most part. First, they're very comfortable to wear, even for extended periods of time. For my side-sleepers, you'll definitely feel them while you sleep but they don't get painful like airpods do. The silicone parts are one of my favorite aspects of the earpods. They make wearing them extremely comfortable. I wore both in for exactly 1 hour and the battery hit 85% so I'd estimate that one charge lasts a little over 6.5hrs as long as battery distribution is consistent. You can move around a lot with them in and they will not come out, the only exception being while eating. The connection time is very fast and there is UI displays for the devices you connect it to so you can see battery (at least on iPhone and Mac). Noise indicators also signal connection. When putting it back in its case, they've attached magnets so its clean and easy. The box is slightly bulky but it's light-weight with a slight plastic feel. The noise cancellation is at a comfortable level for me personally but for those wondering its not exactly full noise cancellation. It cuts excess noise by about half but I find that its a more comfortable experience than full noise cancellation but for those wondering, don't expect it to be airpod pro level noise cancellation. It gives you enough to focus without being completely cut off from your surroundings. The price (22.34 w/prime) is very good for the quality.

These just work! I'm no audiophile but they sound good enough to me a lot of my listening is to podcasts, but also some music. Sound is better than average. I also have Samsung Buds, and Samsung Buds 3pro and Ear Fun Air Pro ear buds. The Buds 3 Pro have the best sound of the group, but overall I like these CMF buds better than all the rest! Sound is adequate, but functionality is where they shine, quickly hooking up to a device and then quickly switching to a 2nd device smoothly! I wear them working out, and I sweat heavily, I have never had a problem charging them straight from my ear following a workout. The higher priced Buds 3 pro I have to towel off 3 times before they will begin charging.If you want a reasonably priced earbud that sounds decent and works flawlessly and has a good battery life I highly recommend these....no bells or whistles, just good functional sound

For the money, these sound great. It's not perfect and has some reasons I'd say theyPros:satisfied with the sound - produce punchy lows and clear highsBattery life is as advertisedThey Ddn't fall out of my ear even during bike rides or jogsThey connect to my pixel 9a phone instantly when I take them out of the case.Cons:Noise cancelling feature gets overwhelmed in some situations like very loud sharp noises. Had these on while using a saw and the noise caused ANC to produce popping sounds in my ear which was very uncomfortable and worse than just turning off ANCI grew to really hate the case. It opens like a clamshell but it's impossible to know which way to open it in the dark or by feeling around without trying every orientation. Modern cases open in a clear direction that can be felt. One handed opening while doing other stuff doesn't work.I am not very picky about ear comfort. I've had my share of buds over the years and these are the first pair of ear phones that really start to hurt after a 2-3 hours. I tried all sizes and that come in the box and the medium fits the best but doesn't feel great long term. Could just be my ear shape so take this with a grain of salt.Overall, I can't complain too much for the price. If you cant or wont spend more for ear buds, I would take these and be happy. They mostly fade into the background and let me enjoy music in peace.

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 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: +6MID: +1TREBLE: 0Ultra Bass: Level 5For 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.

The CMF Buds 2a really surprised me with everything they offer for the price. The sound quality is very good, with powerful bass, clear vocals, and noise cancellation that actually helps in noisy places. They are also comfortable to wear, and the battery lasts a long time.In terms of value for money, they are one of the best options I have tried. They include features usually found in more expensive models, the connection is stable, and the app makes it easy to customize the experience. I would definitely recommend them if you want something affordable and high quality.

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 foreverUpdate: 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.

The noise cancelling works great, my only complaint is that the transparency mode is a bit too quiet, and id prefer it isolating the vocals more. it lets in a fair bit of wind, but hopefully this is added in an update.Other than that the noise cancelling works well in cars, public transport and at home. Its not great at higher frequencies but will block out low and mids, as well as static noise (air cons, fan noise ect).Sound quality is great, not studio quality or anything, but its got a good amount of bass and sound isnt muffled or distorted.Build quality is good, doesn't stand out but for the price its very acceptable. They can get a bit uncomfortable to wear for longer than 45 mins, but after taking a 5 min break it feels fine again. I also really like the design, i got the orange colour to be a bit fun and they look great when wearing them.Also i really like that you don’t need an account for the app. Very nice.

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 :)

Dont really like the voice quality

Very good

音質が良い、使い勝手も良い、プライムデーに買ったのでコストパフォーマンスも最高
