Review: These earbuds definitely surprised me, but I don't think they will replace my Soundcore Space A40's - If you're looking for a discreet pair of earbuds to use for audiobooks and podcasts, these are perfect for you. If you're looking for discreet earbuds for music or calls, I would go with the 1More Comfobuds Mini. Here's a list of the pros and cons of these earbuds, and a few more details as to why these earbuds are not for music. Pros: Pairing - The pairing process for these earbuds is very simple, and once the earbuds are paired, they connect to your phone quickly. Size - These earbuds are tiny. I'm amazed that a driver, a battery, controls, and Bluetooth can fit into such a tiny earbud. They are incredibly lightweight; they almost feel hollow, which is not something I would not expect for something so compact. Battery life - These things last almost 8 hours... that's not including the case, which gives them 3 more charges. That's 32 hours of battery life. How? Comfort - The earbuds by themselves are very comfortable. You can't even feel them after a couple minutes of usage. They come with ear fins, too, but they are very uncomfortable. I ended up throwing them away. I would try them if I were you (I have very small ears, so it might just be me), but I think that they also destroy the purpose of getting tiny earbuds. Controls - The controls are a bit wonky, and there's no way to change them, which isn't something I would expect at the price point. However, they are very functional, and I prefer button controls over touch controls because they are more reliable. Cons: Connectivity - These earbuds work well in mono mode. There's no audio clipping, and you don't have to be close to the device you're paired to, but when you use both earbuds, the earbuds become almost unusable. They constantly clip for the first 30 minutes of usage before they work consistently. If your device is close, it clips. If it's far away, it clips. The only time I've gotten it to not clip is when I had my phone about 5 feet away and stayed still. For some reason, though, if you listen to an audiobook or podcast, there's little to no clipping. Sound quality - It's what I expected. Everything sounds just fine except for the bass. There is 0 bass. I think it's because of the lack of a proper seal (the earbuds have an odd curved shape) because if you push them in you can hear the bass just fine. Mics - These earbuds don't have mics, so the only thing these earbuds do for calls is receive audio. I think it was an acceptable compromise for the size of the earbuds, though. Edit: 4->5 stars I don't understand how Bluetooth connectivity works, but after being paired to my phone for about 2 weeks, the connectivity issues disappeared. This could've been an issue with my phone, because I updated it about 2 weeks after receiving these earbuds, but I don't think I'm the only person who's had trouble with these earbuds staying connected. Also, I figured out how to get a proper seal with these earbuds. Now that the drivers are far enough in my ear, I have to say these have exceptional sound quality for the price. To get a proper seal, twist the earbuds so that the drivers are below the canal, then twist upward until it makes a seal. Now that I've gotten over 2 of the 3 issues I've had with these earbuds, I have to say I highly recommend them as long as you don't care about the lack of mics.
Review: Reliable and Consistent - These earbuds have been great. I'm on my 2nd set in about 18 months. Didn't even shop around just went to my order history from 2021 and re-ordered a few days ago. For appx $30 there really isn't a better option. I've tried 3-4 different types and landed on these. Sound quality is good. Battery life is good. Charging case and use of, is good. Fit and comfort is good. Using for phone calls works fine although not the greatest. But I didnt buy them for that reason so don't care. If you want a quality and affordable, discreet earbud option I'd recommend these.

### ⭐⭐⭐⭐⭐ Reliable and Consistent

### ⭐⭐⭐ They got worse
*by A***E on August 16, 2024*

I used to love these earbuds. I bought a pair about a year ago to use at school and they were genuinely a lifesaver. They somehow survived the washer twice and had an honestly astonishingly long battery life (by my standards). I only ended up getting a new pair because I accidentally crunched the case of my old ones, causing them to stop charging correctly. I was impressed by the new ones. The new case feels smoother and has a better locking magnet. The packaging’s as more professional and the sound quality was better. Imagine my horror when I take them out of the case only to find they make a very audible noise when they turn on, which they do the moment they exit the case. I scour the Amazon listing, instruction manual, and internet at large to find that there is no way to fix this issue. If you’re looking for cheap, sleek earbuds, these are a fairly good choice. If you’re looking to sneak earbuds into school or work—which I assume most of us are—you better take them out when it can’t be heard, otherwise you’re screwed. If there is a way to turn that noise off, this would be an easy 5 stars. They’re resilient, visibly discreet, and long lasting. However, that sound ruins the “discreet” aspect. I’ll have to find other earbuds, which saddens me because I was such a big fan of these.
