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

Great sound quality, awesome accessibility, overall very happy. Deep punchy bass, can sort of drown out the normal sound if you put the bass too high in the app, but ive found a good happy medium. They feel amazing in my ears, havent had any issues with them falling out or feeling loose. Comes with some different ear plug sizes, though the normal ones fit everyone ive let use them. Battery life is quite nice, usually can get multiple days of use off one full case charge. One of my favorite things is how quick it connects to my phone and how there isnt a “bluetooth connected” voice, i pull them out of the case, it connects within a second, gives me 2 beeps to know theyre connected and im good to go. Got the black colored ones, probably shouldve got a lighter color given the fact that i lose everything 😂😂😂 They do have a find my earbuds section in the settings page of the app though and it has definitely come in use a few times. If youre thinking about getting these. GET THEM, great sound, build and app quality. I have not regretted the 30 bucks spent one bit.

+ : 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 case I'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.

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.

For the price, this product is fantastic. The ANC is not great, it's kind of like wearing ear plugs inside, but once you play the music it gets much better. I'm walking through Target and I can't really hear the loud kids, while listening at 70% volume. The default mode after turning ANC off is fine. I have worn the premium product line, this is clearly worse. But for the price, this is a better deal. I would recommend this to anyone who hasn't already bought themselves fancy top of the line earbuds. I can't believe the price. How do they work their magic?

I had these earbuds for past 3 days and they working as expected even better than expected. 1. Sound quality - these sound great for the price. You can adjust EQ level in the app as needed. 2. Touch control - These have touch controls on the side which you can customize as per your liking and control almost everything. 3. Call quality - I work at NYC and use my headphones in loud subway. Person on the other side was able to hear me loud and clear without much disturbance. This is big plus for headphones at this price range. 4. Touch control haptic feedback - these don’t have haptic feedback. And this is only negative point but does not matter considering price. 5. Noise cancellation - I didn’t notice any noise cancellation. Again this can be ignored for price. 6. Battery life - it’s good, considering I have only used it for office to home and vice versa and did charge it in office. Until now it checks all the boxes and hence 5 star.

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!

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.

They don’t sound as good as wired Apple EarPods, but the sound is acceptable, and with the app, it can be tuned to sound close to EarPods, but there is too much bass in the sound. At the volume level one click above silent, the earbuds are louder than EarPods at that level. It can be a little frustrating when listening in a quiet environment. There is no Left and Right label on them. They can fit in the wrong ears, and they sound bad when they do. I wish changing the ear tips were easier. When I wear them a long time, the earbuds hurt my ears. (Maybe because I don’t have the correct ear tips in.) Apple EarPods have not hurt my ears like that. Sometimes the earbuds have worked themselves out and feel like they might fall out of my ears. EarPods have not felt like that, maybe because the weight of the cords keeps it in place or maybe because of the shape. The low lag mode worked well enough for me. The manual that comes with it is small and has tiny print. I noticed that when I took the earbuds out, the music kept playing. I wish it could detect when I took them out of my ears and paused music. It had a firmware update when I started using them, so they may be more secure than cheaper earbuds that get no firmware updates. The low price makes the performance acceptable.

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

i can rate 8 /10 for this product by its amazing sound quality , anc is good not excellent , call quality is good , battery life is good enough , comfort and value for money is remarkable .

Really good deal. Great quality for the price. I was really surprised.
