Great buy! Truly !

Color: Dark GreyVerified Purchase

The media could not be loaded.

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.

Yes, buy these earbuds, they're very fun

Reviewed in the United States on September 8, 2025

Color: Dark GreyVerified Purchase

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.

Good Quality and Excellent Value

Reviewed in the United States on August 11, 2025

Color: Dark GreyVerified Purchase

Works exactly has advertised and the price was great during a Prime day special.

+Audio quality is good, solid bass and overall volume.
+Noise cancellation options work exactly as you would expect.
+Pairing was painless.
+Battery life and charging is easy and meet or exceed my expectations at this price point.
-Control app is a little light on features and some options can't be fully customized.

I'm not giving it 5 stars due to long-term comfort issues after sustained use and I would like some of the gesture control options in the app to be unlocked so hey can be adjusted. I understand why they are not customizable by default, but it feels like that would be an easy warning dialog that requires you to click through before allowing a change. Make it big and scary to dissaude people from casually clicking, but still provide that freedom.

Amazing value

Reviewed in the United States on October 31, 2025

Color: Dark GreyVerified Purchase

I literally cannot imagine any competitors being a better value. This is from the perspective of a skateboarder.
1. The noise cancelling is overall pretty good. It will turn off automatically when it detects wind, which is nice. It’s not suitable for you if you do things like cut/grind steel and make loud metallic banging sounds all day, the ANC clips and it’s pretty unpleasant. Aside from the it’s good.
2. No issues with the buds falling out.
3. Sound quality is overall very good, I think. Maybe not the clearest audio on earth, but it has very good bass response in my opinion.
4. Battery life is acceptable, can’t expect too much here considering how small and lightweight they are.
5. I don’t use the touch controls at all, not very useful in my opinion.

Overall I love them, unbeatable for $30.

Noise cancelling is great, sound is great

Reviewed in Australia on September 16, 2024

Color: Sliver OrangeVerified Purchase

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.
