First week review
I hardly ever write reviews but here is the rare exception. I work a rotating swing shift that has given me severe shift work sleep disorder.I’ve spent 20 years buying every crackpot hairbrained product to try to help me get a little sleep. My go to was acoustic sleep , a fine product about half the price as the A-20. The acoustic sleep has one fatal flaw, it has no passive noise reduction, you hear ambient noise that’s louder than the device but that’s due to its product design. I almost didn’t give the A-20 a chance because I wanted active noise reduction…man am I glad I did. As a side sleeper these things are comfortable and don’t fall out while I sleep, but the biggest draw is the combination of excellent passive noise reduction and whatever sounds you like to sleep to ( for me its rain) . They do an exceptional job of insulating me in the sounds of the thunderstorm , isolating me from the outside world.I have 3 college young men upstairs and they run across their apartment a lot, I cant hear them or most ambient sounds with my A-20s.( I guess when they throw a party that will be the big test) I haven’t even explored the many features of the app, first nite I went simple with one of the loadable sounds ( thunderstorm) and I was amazed how well they worked…Im happy with that . They are a little pricey but after the first night I realized what a great value they are. (Customer service is fast also.)2nd week updated…you have to keep these buds clear/clean of earwax or they will not work. My left bud stopped working. I examined it to find a ear wax buildup on the mike/speaker on the inside of the bud.After cleaning all was well. Im still happy

I like them
They fit comfortably. They do block outer noise well. It can automatically go into sleep mode when it notices you fell asleep watching something then it will play the sleep sound choice you pick. If you choose not to do that it will just play whatever you are watching or listening to instead.My only issues are the app is a bit irritating trying to figure out where to go. Individual sounds are under âstaticâ instead of the button being names something that tells you there are multiple sounds to choose once pressed.They need to create an actual button to press for connecting once you put them on. Right now you click the small words ânot connectedâ to make them connect. When you wake up they will say not connected again but they have been working all night. I sometimes have to place them back in the case and back in my ears to connect and have it sync how my sleep did. Wearing and connecting is the only way to access the toggle for sleep mode on and off, alarms, and controls. It would be nice to have this screen as an option across the bottom at all times. Sleep history tells you awake time, light sleep and deep sleep, how many times you woke up, how many times you turned, and what position you slept in by percentage. This comes to my other issue. It says I’ve slept âproneâ, which is on your stomach, and i so not ever sleep on my stomach. So it is mistaking a side sleep for a prone position sometimes.Ive also reached out to them and asked them to have the sound section be more accessible for the visually impaired since my blind father would like to get some. Currently they sounds say âbuttonâ when he uses voiceover instead of rain or stream etc. The rest of the app is fairly accessible and the AI sound options will work with voiceover.

Phenomenal!
If youâre looking for a pair of sleep earbuds that truly deliver on comfort and battery life, the Soundcore Sleep A20 Earbuds by Anker are a standout choice. Iâve worn them all night, even as a side sleeper, and theyâre so comfortable I often forget theyâre in my ears. The battery life is impressive-easily lasting through the night (and then some), so you donât have to worry about them dying before your alarm goes off.One of my favorite features is the configurable EQ in the Soundcore app, which lets you tweak the sound signature to your liking. Thereâs a preset that softens loud noises and balances the sound, which is perfect for narrated audio or podcasts I like to fall asleep to. The built-in library of white noise and nature sounds is another plus, and you can even save a selection directly to the earbuds, so you donât need your phone nearby or worry about notifications waking you up.On the downside, I found the touch controls a bit too sensitive-theyâd sometimes trigger accidentally as I moved in my sleep. Thankfully, you can disable them, which I did since I keep my phone close for any media or volume adjustments anyway.If thereâs one thing Iâd love to see in a future version, itâs active noise cancellation. I know thatâs a tall order in such a tiny and comfortable form factor, but it would be a game changer for blocking out even more ambient noise.Overall, the Soundcore Sleep A20 Earbuds are a fantastic investment if you value a good nightâs sleep and want a customizable, comfortable, and reliable solution for bedtime audio.On site note: If you’re having trouble making an account in the app, it might be because you had a Eufy account at some point. Apparently Anker and Eufy share the same authentication system, so if you have one, you have both. That was my only pain point in setting up the device, and caused me to scratch my head for a few.

Disappointed.
Wirecutter recommended these so thought I’d give them a try. Even though there are tons of options for white noise, somehow they all sound like really grating TV static instead of more like a soothing box fan noise (I tried them all, I promise!) As noted, they are not noise cancelling, so didn’t really help with the loud construction. I like that they’re small and can be used for side sleepers, but these didn’t work for me sadly.

Avevo le Bose Sleepbuds che ho restituito per disperazione. Queste Anker costano meno della metà e risolvono tutti i problemi delle Bose: una vasta libreria di loop noise e ambientali di tutti i tipi, addirittura combinabili fra loro; le Bose ne avevano pochissimi. Loop di lunghezza sufficiente a non far avvertire la ripetizione, senza elementi riconoscibili; quelli delle Bose duravano pochi secondi ed avevano elementi distintivi, per cui era inevitabile accorgersi del loop, cosa estremamente distraente quando si cerca di addormentarsi. Trasferimento dei loop sugli auricolari in meno di un minuto; con le Bose ce ne volevano dieci. Quattro loop precaricabili; nelle Bose solo uno. Grande autonomia, dopo una notte gli auricolari in modalità standalone sono ancora al 70%; le Bose arrivavano con fatica alle otto ore. Comandi locali (volume, stop, cambio loop) tramite tap; con le Bose ci voleva l’app per qualunque operazione. Comode e altamente personalizzabili: 4 misure per l’elemento interno e 3 per l’aletta che va nel padiglione dell’orecchio. Buon isolamento dai suoni esterni. Infine funzionano non solo in modalità standalone, ma anche come cuffie bluetooth standard, quindi per musica, podcast etc. Insomma consigliatissime.

I have chronic pain, fatigue and insomnia. I cannot bear lying for hours in pain in silence with my mind racing. I’m used to using apple wired headphones to sleep as they fit best in my ear and give great sound fidelity to me. They’re also under £20, and thank god, because they nor airpods are built to last.Someone on Twitter, a friend of mine actually, recommended these when I asked about people who slept with music/earphones. Wired ones always get tangled, and even if you did risk airpods, their battery life is awful and earwax would break them beyond warranty. I’m so glad I gave them a chance.Finally I can fall asleep and turn over as much as I need without needing to solve a wire puzzle. The headphones last JUST long enough if you somehow get a full 8 hours, with some room left over. They charge quickly, as I found out at 1am in a panic. Normally I hate gel earbuds and they never fit? These ones? Perfect out the box. Come with natural noise cancellation which is great for sleep.I don’t bother with the app. The product is still worth it just for night music listeners like me. The sound quality is a couple of notches below apple airpods/wired headphones imo, but better than most wireless headphones I’ve used. I didn’t even get these on sale, but it was worth it at full price.

a pair of earbuds that you can lie on your side with !.They fit far better than anyother for side sleepers.A soft pillow would work best with them,my only concern is lack of noise cancellation.

Wow! I’ve got a pair of space one’s (cup headphones) and they have been amazing so had no issues in looking at other models. Wanted something to help me sleep at night, and as the other alternative was over three times the price I bought these.They have over delivered on everything.They’re tiny, comfortable, can’t feel them in ear when sleeping (I’m a side sleeper) sound is amazing! Obviously don’t expect mega base, but more than enough to use out and about as well. Clear sound, battery so far has been as described.Only negatives I’ve experienced so far is the sleep sensor for the relaxing sounds seems to be off an kicks in mid song as I’m listening to tunes in bed. Besides that currently my go to buds. Would buy again. Let’s see how they last in the long run as they replaced my Samsung buds that I’ve had for nearly 9 years.

Decent headphones however the Bluetooth disconnects after 45 minutes every session, and despite what the manufacturer claims these DO NOT work for side sleepers at all. The headphones shut off when you lie on your side, they are not designed for it in any way shape or form.
