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.

Survivability is great
I got these to use at work. My job consists of a lot of repetitive tasks and not a lot of social interaction but we are not supposed to technically have ear buds. I got them because they blended I'm pretty well especially with my hair down. The ear buds don't have the best sound quality I have had but they are still pretty good for the price. I have had them for a while and was pretty satisfied but wasn't complaining blown away. Until about an hour ago. The ear buds a pretty small and im really good at miss placing things so I ended up losing one of the pairs somewhere. It's been missing for about a month. Didn't bother me to much because I only use these as work and I only have one in at a time. Battery lasts about 6 hours playing music none stop and about 8 or so hours when I pause music for extended periods of time. Anyway. I was doing laundry and I found my missing earbud in the dryer. Freaking out at first because I thought this was the lonely survive. To my surprise it was the missing soldier. It was melted a little bit but it still showed the charging light when I put it in its case. After it charged I tested the sound and it still works. Sounds just like it's pair. It has only been an hour since I found it from the dryer so it might die on me later but I am still amazed. Long story short. These are great

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.

Subtile earbuds that allow you to listen without cutting you off from your surroundings.
Great product for why I needed them. They are very subtle, and easy to hide in your ear. They block zero sound so you can easily still hear the world around you. They occasionally have connection issues between each other, but that can usually be solve by shaking your head, switching ears or just using one ear bud. Using them for several hours daily they lasted me 8-10 months before one of the ear buds stopped holding a charge. I definitely feel that I have gotten my money's worth on these.

When it worked, it worked pretty well
Tl;Dr I'm not giving 1 start cause while it worked it worked well and I liked it. I'm not giving more stars cause it died abruptly and seemingly without cause. I like the shape, I liked the sound quality, I liked the battery life but then it just died. It says it's waterproof, it kinda is. Been using it regularly since it arrived and I was impressed with the headphones and case cause I hadn't needed to charge the case since the first charge. Yesterday I used the in the shower and it seemed to work just fine during and after. This morning I put it to charge at home and it was charging like normal. Came to work and put the case to charge again and now it's just dead and there's a sort of burnt wire smell to the case and one of the earbuds is just not reaponding. The case isn't charging itself or charging the one earbud that still works. I'm legit disappointed cause I actually liked these. I'm not however, surprised cause the case seemed flimsy from the get to, the cover rotates around 365 and feels like it'll break if you look at it too hard.

Perfect :з i love them!
Okay guys so I started my search for invisible earbuds when I was told at my job I cant listen to music, even when pushing carts! ( I work at a grocery store) anyways I wasnt able to wear my normal headphones bc they were the big kind that sit on your head and are visible. I was looking for invisible earbuds and found lots that look the same but after some searching I came across these! they are basically tan airpods without the tiny legs that airpods come with. the battery life on them are about as good as classic airpods so im not complaining, as its long enough to last a 4 hour shift! now, i have tiny ears and the earbuds are a tad large but they arent too big to fit inside as long as you adjust them properly and they will also not fall out if you shake your head. Now lets talk about how inconspicuous they are. my skin tone is kinda pale so the tan earbuds match my skin tone. they are roughly the same color as a hearing aid. now if you have short hair (that doesnt cover your ears) they MAY be visible but only to someone that is speaking to you, as the headphones arent noticable from 10 feet away unless you are looking for them. Luckily, I have long hair that goes to my shoulders, and thats more than enough to hide the earbuds, because without having the legs that airpods have and being tan colored instead of white like airpods, they are completely invisible if your hair is kindof blocking the veiw. im pretty confident i wont get caught with these in at work and im very glad i made this purchase! 5 out of 5, very satisfied. PS. other reviews say that they will randomly connect yo your phone but i have not had an issue with this (i own an android) so perhaps the random connection is IOS related.

Buenisimos para domir... con un pero
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.

Very happy with these!
These are exactly what I was looking for. They charge quickly, last for many hours- longer than I need them for at a time anyway, maybe 5 hours? Connection has been reliable. You can get a secure enough fit that they will stay in no trouble- I love how small and stealth they are. You can still hear conversations etc around you if volume not on blast, if that’s what you want. Great for situations where you still need to pay attention to your surroundings! Zero issues. Would repurchase.

Sound quality great
These are the smallest earbuds I’ve found which is a big thumbs up for me bcos I’ve got very small ears. They also have great sound quality. They’re a big must buy EarPods, you won’t be disappointed.

Distance bluetooth téléphone écouteurs médiocre
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 !
