Great bass, better than airpods, and bang for your buck

Jesus FloresJanuary 15, 2026✓ Verified purchase

Been using them for a week and I'm truly impressed. Comfortable to wear so long as you change the eartip to your most comfortable size. Personally i don't like noise cancelation on any earbuds or headphones so I had that off thru the app. Overall my favorite thing are the sounds in these things, I'm a huge bass lover and mids and these things aced it! Battery has lasted me about 4-5 hrs each earbud, I only wear one at a time though so no biggie for me. The earbuds connect super quick to my android phone and the app is great too. Loads super quick makes the changes on the settings for the earbuds instantly never had a connection issue, easy plug and play. Overall these earbuds blow away any other esrbuds for me like the airpods or airpods pro in terms in the sound quality. For 30 bucks just do it. Definitely won't find another pair of earbuds around this price range with this good of an audio quality. I've tried multiple and none have been as good as these. These will definitely be replacing more airpods, way cheaper and BETTER audio! Read more

Great buy! Truly !

CustomerNovember 11, 2025✓ Verified 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. Read more

Best budget earbuds I've tested

John Galt 2February 18, 2026✓ Verified purchase

Ok...I'm not rating these 4 stars compared to every ear bud at every price point. I'm rating these 4 stars compared to other budget earbuds. These are a truly surprising good value. Pros • Reasonably good mic performance in phone calls driving in the car • Very comfortable • AMAZINGLY GOOD SOUND QUALITY for the money • much flatter frequency response than most earbuds these days • case is easy to open (even with cold dry hands), and stable sitting on a table or other surface... • buds are easy and quick to get in and out of the case Cons • MUST add Comply TWo-220-C foam tips or they'll sound horrible. Night-and-day difference. Unusably-bad with the included silicone tips (at least in my ears), but with those Comply tips they are an entirely different product! • Worst earbud app I have ever used (THREE band EQ???!!!) • cannot single-tap to play/pause, forces you to use double-tap • mediocre ANC • mediocre/bad ambient hear-through • no wireless case charging So who are these for? These are great all-around earbuds for someone on a very limited budget (I've seen them over the past month $24-$40) If someone has other earbuds that they prefer for music, or because of better ANC, or some other specific features, but those buds are junk for phone calls driving in the car, these work better than average for that. Don't get me wrong, they don't sound great in the car, but they do sound better than average these days. Read more
