By far the smallest earbuds available anywhere. The sound quality and battery life is outstanding considering their size. Though I did notice i had to raise the volume way higher than with other earbuds. I normally have my volume around 50%. with the Sleep A10 i had to make the volume 75%. Also the bass is a little too high by default, it almost sounds muffled. setting the EQ to Acoustic (even when listening to non acoustic music) in the Soundcore app brought a bit more clarity to the sound. The battery lasts a really long time. So far i haven't had to charge the case once in the week and a half i've had it and i've been using them every night. I also like that one of the ear wings has no wings. I had another sleeping earbuds from another brand that had no ear wings and I found the fit to be good. The Sleep A10 has an even better fit because of the silicone covering. Glad it has so many options, It would be nice if there was a foam eartip option in the future. The build quality is fantastic as is expected from Anker/Soundcore. The case and the earbuds themselves also look really slick, they have a really good looking pearlescent look that doesn't really come across in most photos or videos i've seen online. The sliding mechanism of the case is very satisfying and it's not incredibly loud like airpods clacking sound. They make more of a lighter sound when closing. One note about the app, the quality of the sounds in the sleep mode seem to be really low bitrate. They sound very compressed like low resolution in a way that is too distracting to me so I never use the sleep mode. I wish there was a way to load your own mp3s in even if it was limited to only just 1 or 2 files. Another great thing is the latency. When watching videos there is no perceptible latency! This was a problem on a competitor's earbuds.
I’m a side sleeper and these are one of the few earbuds I can sleep with and not have my ears feel sore in the morning.
One big problem though is that the case seems to be staining and I can't find out where it's coming from. I am unable to remove the stains with alcohol. I contacted support for help and though they were not able to help me solve the issue they were really responsive along the way and even offered me a 10% refund on my purchase, pretty good experience with them! My advice is be careful where you put the case down.
Overall the battery life, sound quality, and comfort are great compared to competitors. And you have the excellent warranty and support of a major brand like Anker unlike janky no name brands on amazon. If you're looking for earbuds that let you sleep to your own music or sounds, the Sleep A10 is the only worthwhile option on the market.
