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.

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.

They got worse
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.

SEVERE quality drop. Not worth the money any more.
DO NOT BUY THESE ANY MORE. SEVERE QUALITY DROP. So I've been buying these as an inexpensive headphone I can use at work that lasts about a year or so. Considering I use them 8hr a day, five days a week, that's pretty good. The price crept up but that was okay. But the newest buy, picked up November 25, are not the same product. The battery barely lasts four hours, there is no low battery warning- they simply disconnect on you when they run out. Audio quality is worse. The charging situation is worse, as it's common to put them in their little cradle and have them simply not charge. There's clearly an attempt here to save money by the company without lowering the price, but they're now something I'd refuse to pay more than $15 for. These have become awful, disposable land waste.

They work well, with some minor flaws
I have owned several pair of these and use one earbud for an average of maybe 3-4 hrs a day, 6 days a week. With my usage, a pair normally lasts me about one year. The charging case becomes so useless at that point that it is no use. The earbuds still work and charge but there is no way(that I know of)] to charge them any longer. The only other probs Ive had is the little screen that serves as the speaker cover has fallen off and been lost before. Otherwise, these have performed nicely. The sound is good enuf for me. They are simple and responsive to connect...usually. I personally find that they lock in my ear pretty well. I continue to use these because I use them at work where we arent supposed to wear earbuds(per work rules), and these are the most discreet earbuds I have found...and they are pretty affordable. This also explains why I only wear one at a time. This is a cheap, Chinese product but it serves its purpose well for what I need. I'm would expect them.to last significantly longer for someone that doesnt have such high usage, as I do. They do not have noise cancelation and have a physical button...which I kind of prefer.

Sound quality is good, connectivity range almost 20-25 feet, battery backup is 2 hrs music and 6-8 hr standby and calling 1-2 hr continues

Botón físico y sin tapón intraural. Estupendos para dormir, no se me caen, y tienen la capacidad de reproducir a un volumen muy bajo. Ojalá no hubiera una persona gritando en mi oído cada vez que los auriculares se conectan, se desconectan, les queda poca batería, o se encienden y se apagan... porque realmente serían de 10.

Le son est bon pour le prix ! Par contre dès que je mes mon téléphone dans mon sac il ne capte plus je dois garder mon sac sur mon ventre pour le peu que je regarde sur les côtés et les écouteurs se déconnecte... Niveau taille idéale pour de très très petite oreilles oreilles !
