Review: Best sleep headphones I've ever tried. *UPDATE broken about 9 months after purchase - UPDATE #3 The second pair are now dying after about an hour of charging. I use them every single night all night so I guess I can't complain. What I am writing is that Anker's customer service is outstanding. Since these are still under warranty they are sending me yet another replacement. I will say again these really are the only decent option when it comes to sleep earbuds, and with there customer support you can't go wrong. UPDATE #2 7/22/25 I moved this back to 5 stars. Anker sent me a new pair and they've been working well for months. I still can't figure out how to completely disable the battery alert alarm but it's not that bad. They get 5 stars because there is simply nothing out there that comes close to these at this price. If you are looking for active noise cancelling earbuds to sleep in just buy these, they are the best option out there. UPDATE 1/9/25 These aren't even a year old and the right earbud is no longer working. They work well when they work but if they only last this long I would not suggest purchasing. I've had these headphones for two nights so far, and they have been surprisingly great. I will update the review if that changes. I have had difficulty sleeping my whole life and am very noise sensitive. I have tried everything to block out noise to sleep. I will keep this review short and to the point, but these are the best sleep headphones I have found. So far the battery life has been great and they've lasted through the night each night. They are very comfortable to sleep with. Not perfect but by far the best I have come across. They are well made and sturdy, but we will see. The one bad part so far is the Anker App. It is so stupid. The earbuds cut out when I use it, and if you want to listen to white noise for sleeping and then switch to a different app to read or something the noise stops. It is completely useless, and almost caused me to return them. Whoever makes these apps should have them field tested before selling the product. HOWEVER I just simply use a white noise app on my phone and since it is connected via bluetooth it works great and you can just circumvent the app. Anker should make these earbuds for nothing but sleep. Don't try to make them regular everday earbuds that CAN be used for sleep, just make them for sleeping. Removing a star. So while you are sleeping if the batteries die the headphones have an alert to tell you this. So they wake you up to tell you the battery is dead rather than just let you sleep.
Review: Good sleep earbuds, but Soundcore will brick them with firmware updates, so beware - I have been an Anker Soundcore Sleep Earbuds customer since the beginning. I purchased the original A10, then backed the A20 in the Kickstarter and purchased a second pair (for my wife) from desertcart. I also backed and received the A30 on Kickstarter and are using those presently. So, I don't give a review like this one lightly. I got my original A20 earbuds back in May 2024 and the 2nd pair in Jan 2025. Honestly, they are awesome. Sound quality is great, periodic cleaning kept them working well, they mask noise well and the battery life was perfectly fine until.... A month or so ago, my A20's got the 1.57 firmware update from Soundcore. I didn't think anything of it at the time, but the right earbud just started refusing to charge above 30%. It would charge from 0% to 30% just fine, indicating it had good contact with the pogo pins. But it simply would not charge over 30%, ever. The left earbud charged perfectly fine to 100% every time. I did some research and it turns out many others are experiencing the same issue, specific to the 1.57 firmware update. Apparently, that firmware has a known issue where it messes up the battery calibration of the right earbud and causes this exact problem. So, in short, Soundcore pushed a firmware update to my A20 earbuds and in the process made them unusable. You might think "Well, they're in the 18 month warranty, just get them replaced". I did reach out to support, and they agreed to replace the earbuds, but what happens when Soundcore pushes out a firmware update that breaks the earbuds when they are just out of warranty? If the warranty is 18 months, and Soundcore can break your device outside of the warranty at any time, this means that the device has an 18 month lifespan. So, if you are going to purchase these be aware that they should be considered disposable and you probably won't get more than 18 months of usage out of them given the above. UPDATE: 2025-12-20 Soundcore sent me replacement A20's for the ones that they damaged with their 1.57 firmware update. These new A20 sleep buds came with a much higher revision of the firmware 03.22. So, it looks like the firmware now skips from 1.50 to 03.22, as Soundcore definitely has pulled 1.57 off their servers (since it broke so many customers' A20s). But... the replacement pair Soundcore sent me were defective. The right earbud consistently discharges at more than 2x the left earbud. So for example, after 7 hours of Sleep Mode white noise playback, the left ear bud would be at 70% while the right ear bud was at 30%. I am continuing to see if I can get Soundcore to actually send me a functioning replacement for the sleep buds they broke. We'll see what happens... UPDATE: 2025-12-29 Soundcore sent me a second replacement for the defective A20's that they sent as the first replacement for the A20's they bricked with the 1.57 firmware update. So, this is now the third pair of A20s... This pair appears to work correctly, and the right and left earbud discharge battery at the same rate and look like they will achieve 12-14 hours of playback at 50% volume in Sleep Mode. So... after several weeks of back and forth, and multiple pairs of bricked or defective earbuds, it looks like I have a properly working pair again. Support was very helpful about all of this, and I found them receptive to all of the issues I was experiencing, so I don't want to be disparaging of Soundcore support at all here. In general, I've found them good to work with. But... I think the quality control of the Soundcore products is not great. I had battery discharge issues with my original A10 earbuds, and went through a similar replacement dance with those as well. It seems like Soundcore's sleepbuds are prone to battery issues very frequently, since I've now seen issues with uneven battery discharge in 4 separate pairs of A10 and A20 earbuds. My wife's A20 sleepbuds are still on the 1.50 firmware, as the 1.57 firmware has been pulled by Soundcore. I asked support about this and they confirmed that there were multiple hardware revisions of the A20's, and the replacement A20's that I got (which are on the 03.22 firmware) are a later hardware revision than the A20s that were on the 1.50 and 1.57 firmware. Support left it very ambiguous as to whether or not hardware with the 1.50 line of firmware would even continue to get firmware updates, or if that hardware revision has been effectively abandoned by Soundcore. If you are going to purchase these, you need to make sure that the firmware is the 03.22 line, and NOT the 1.50/1.57 line, since that means you have an older revision of the hardware.

### ⭐⭐ Would be 5* if they worked longer than 3 months
*by D***N on May 18, 2025*

UPDATE: After making my original post Anker contacted me and offered a full refund. With the excellent customer service it may be worth the gamble to see if you get good units. I'll probably be back for the A30 Sleep series whenever that's released, I hope those work better. These are great earbuds.... for the first 2-3 months. Truly the best sleep headphones I've ever used. Most of the others are cheap ones from Amazon. The Anker branded sleep headphones were the first ones I found that didn't have a very loud voice yelling in my ear "CONNECTED", "DISCONNECTED", or "POWER OFF" in the middle of the night waking me up. The fact that you can completely disable all sounds on these is great. They're comfortable for me as a side sleeper, but everyone is different, so YMMV. Now the really bad. I've had 2 sets so far, both lasted almost 3 months before the right ear is nearly inaudible. Both sets had the right ear gradually getting quieter and quieter, it's not related to ear wax build up or anything as I've regularly cleaned them and when taking them out of the case the volume is noticeably louder compared to the next morning when it is impossible to hear anything, the only way I know it's still connected is that the touch button still works and the app reports ~80% battery, my audiobook app turns off if I don't shake it every 15 minutes so most of the time I'm asleep within 15 minutes, so these get very little active use and are in standby most of the night. I got my first set replaced with warranty fairly easily, which is really the only reason they get 2*. But for the money these should really last longer than 3 months. The S10's I had before lasted over a year before one of the ears died, which isn't amazing but for that year I had the best sleep I've ever had so the higher price point is worth it, but there's a big difference between the cost being ~30 cents per day to over $2/day before they're not functioning. At this point I don't recommend these, if they worked well for more than a year it would be good but the fact that I've had 2 units fail the exact same way is disappointing. I figured the first time it happened must have been a fluke since very few reviews say anything like this happening, but to have 2 in a row with the exact same problem seems like possibly a manufacturing defect.
