I've only had these Anker Sleep A10 Bluetooth sleep earbuds for less than a week, so I can't comment yet on long-term reliability, but so far, I am thrilled!My wife and I sleep with multiple fans running, both to keep us cool and to provide white noise. So, I did not need sleep earbuds to block out noise. What I wanted them for was to provide soothing music while trying to fall asleep. I have tried normal earbuds, but they are wired (strike one) and uncomfortable if I lay on my side (strike two). I have also tried a sleep headband, but I don't like the feel of the headband while trying to sleep and it was hard to keep the speakers over my ears. Also, it was wired too, which is not going to work with the amount of tossing and turning I do.As I researched possible wireless earbuds that would be comfortable for a side sleeper, I discovered that the Bose Sleepbuds II had been popular but were discontinued. I wouldn't have wanted them anyway since, as I said, my main reason for wanting sleep earbuds was to listen to music, and the Bose Sleepbuds could only play downloaded white noise type sounds.After reading the reviews of these Anker A10 Bluetooth Sleep Earbuds, I was concerned about the reviews that said they did not maintain connection reliably. I was also bummed that the manufacturer themselves said that they are not really meant for reliable Bluetooth connection while outside, since I was hoping to have these earbuds be my one set of wireless earbuds, both for sleep and for walking. For the same reason, I was somewhat concerned about the reviews that indicated the sound quality was not great. But given the few options out there, I decided to order anyway. They were delivered the same day!I was immediately impressed with the heavy packaging and the (almost overwhelming) number of optional ear tips and wings. I was also impressed with the attractive look and quality build of the charger.I was initially confused by the amount of information, prominently displayed in the case, on how to fit the earbud in my ear. I figured earbuds are earbuds and you just push them in until they are comfortable. But I took the time to read the info and started to understand that it is CRITICAL to fit the earbud correctly. Of course, you want to fit it for comfort, especially while sleeping. And, of course, you want them to sound as good as possible. But I quickly understood that these small earbuds, needing to fit flat into your ears to be comfortable while sleeping, could easily have their Bluetooth connectivity compromised by having your ear come in contact with the important antenna areas on them. Also, I had never had earbuds with wings before and had to read the instructions on how to properly insert them and then rotate them to "lock" them in place.I'm so glad I took the time to understand that. I was lucky that the default tip and wing fit fine in my ears and lock in place well. I may experiment with others someday, to see if they can be even more comfortable, but they are plenty good by default. And, looking at how they fit in my ears, I could see that it looked like the proper fit shown in the instructions and this has led to me having no problem at all with the Bluetooth connectivity! Not only have they stayed connected while sleeping (and tossing and turning), but I have been able to use them outside while walking the dog. They ARE sensitive to being blocked, but the only time I've been able to notice this is when covering an ear with a hand (when I was testing how well they blocked outside noise) and when putting my arm across my ear (in one of my weirder sleep poses).For sound quality, I have no complaints. I have never had high-end earbuds, so I'm not the pickiest. They sound fine to me in the music I've listened to, with good bass and treble response.The battery life is not an issue for me at all for me. I have them in the mode where they change to "sleep mode" (playing the downloaded white noise) when they detect I am asleep. I have the music playing while I try to fall asleep and although it can take me an hour or more to fall asleep, the battery last fine for that and fine for switching to white noise after I fall asleep. I haven't kept them in all night yet, so I don't know if the white noise in "sleep mode" could last the rest of the night, but it doesn't matter to me. One reason I may get good battery life is that I do not have the Soundcore app running AT ALL when I'm sleeping. I don't need the sleep monitor function because I already know that I'm not a good sleeper! LOL.For comfort, while side sleeping, I find them pretty good but not perfect. I have never liked even regular foam earplugs in my ears though, and I find these at least as comfortable as those. I get used to them pretty quickly each night and I haven't tried yet experimenting with other tips and wings, since it has not been a big issue.My needs are not the same as everyone else, but I am thrilled with these wireless sleep earbuds so far. Not only do they give me the music I want while trying to fall asleep, with the added bonus of extra white nosie after I've fallen asleep, but I've also been able to use them to listen to audio books while walking the dog. 5 stars from me, for sure. At least so far.

I tried the A20 sleep earbuds, and loved the functionality but couldn't make them fit comfortably. So I thought I'd try the A10s, since some reviews said they're more comfortable. And wow, perfect, right out of the box. Easy to sleep in, even on my side. Great seal, no weird pressure, and unlike the A20s, they didn't make my ears itch. I missed some of the software functions of the A20s, but was willing to live with it for the comfort.But the first pair of A10s I tried would randomly disconnect during the night. Instead of sleep noise all night, I'd wake up to silence in one or both ears. Sometimes they'd reconnect with a jiggle, sometimes I had to reset them in the case. None of which improved my sleep.So I sent them back for a replacement. The second pair arrived with the left bud at 80% battery, and the right but completely dead - first warning sign. I charged them in their case for several hours, paired them to my phone, and went to bed. An hour after I switched from Bluetooth to sleep mode, I noticed the sound in my right ear disappeared almost completely. When I checked the battery levels, the right ear had dropped to 40%, while the left ear was still almost full. That didn't explain the drop in sound, but I decided to try again the next night. I unpaired them, reset them, charged fully, repaired... Same result, but this time the sound in the right ear disappeared as soon as I switched from music to sleep mode. Obviously the right earbud was bad.I tried cleaning the bud (even though it was brand new), and the only other fix I could find online was what is already tried, which was charging the buds fully.So these would be fantastic earbuds, if they worked. But two bad pair later, and now they don't have an actual ship date for new purchases, so I can't try a third pair if I wanted to. Horrible quality control for what could be a great product. No, I don't recommend these unless you feel like gambling you'll get a pair that actually works. I sure didn't.
