An excellent sleep bud.
These are very good sleep buds. They take a little getting used to, the app is a little odd, but once you get used to it, it's easy to use. Take heed of their play time, Bluetooth paired you'll get 6-8 hours, "sleep mode" (unpairs and uses their in built in and customisable sounds) gets 8-10 hours. No noise cancelling so snorers still break through. These almost rely on being earplugs like. For side sleepers these can get a little bit uncomfortable if you have a hard pillow. But generally these are comfortable and tuck into your ear quite nicely. I've had to have these warrantied twice, 1 for poor battery life, Anker replaced after a few emails, second one the left bud battery swelled up and broke the case. Anker has replaced them both times with an exchange unit. I cannot fault Anker with this at all. I will get my use and currently justifying spending the same amount on their new A30 buds.

They fixed most of my nights, as a insomniac light sleeper who listens to music!
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.

Using earphones meant to block noise should not be that complicated
Using earphones meant to block noise should not be that complicated. You need to put them in a sleep mode for over half an hour for them to create a noise profile, and that is not possible, because the earphones keep disconnecting. Although they are very comfortable and I imagine sleeping in them would be comfortable, I think the fact the sleep mode means it plays a random noise track instead of just cancelling noise, is a bizarre choice for the design. Anyone looking for noise cancelling to be able to sleep isn't really looking for this. The mode is automatic so whenever the earphones think you're asleep or when they disconnect from your phone, they will play the noise track. First of all, that could wake you up, especially when you're a light sleeper; 2nd of all, I didn't expect something like this to happen with earphones meant for sleep. I thought maybe you could just use some tracks in the app for unwinding before you fall asleep, what sure you can do, but then this shouldn't play when you're asleep. Your ears work when you sleep, there's no way you're getting rest with the music directly in your ear all night. And it seems like the noise masking feature is just adjusting the loudness of this track, which is completely missing the point, I can do that with regular earphones. Now, coming back to the noise blocking feature. I think this is a really bad choice to sacrifice active noise cancelling for this questionable noise profiling that uses the microphone in your phone that will either turn on or not. Also, that makes two devices use power and you need to charge more, and use more power to keep them up in the long run... It's not so efficient. The earphones have no internal microphones to block the noise themselves and blocking noise manually just via the earphones being in your ears doesn't make much difference compared to any other earphones that don't have ANC or simple earplugs that cost fraction of the price of these earphones. I think this is a bad tradeoff with these, especially that the sound library for pre-programmed tracks isn't that good. Some of the tracks for focus e.g. are the same as other tracks meant for unwinding. Any meditation app will have better options. It would be better if the earphones had simply a sine wave generator with presets instead of default music. Also, the sound quality is not good on these, and compared to other Anker earphones I have. They are also much quieter, so not great for listening to music. Ah, and they're not white as the description says. They're beige which is not a bad colour, but that's just not what the description says. Too bad I have to send them back, I was hoping to be able to use them around the clock for being comfortable, but they're just frustrating to deal with.

These earbuds work well 98% of the time...however....
...the left earbud which is set up for use to reduce sound, and also to go from Sleep mode to Bluetooth mode. It has the issue that it is either ignoring the taps I am supposed to give to change the setting or it changes from Bluetooth, to sleep mode without my permission and input, which is frustrating. I think it does this as a precaution for people who fall asleep. That is literally the only glitch they have, other than that, they are fantastic earbuds! The sleep audio selection is very good, and if I want to listen to a podcast, or YouTube video etc, I set it to Bluetooth mode and I can listen to any audio I like. it works extremely well. The battery has a long life. So far, I have fallen asleep before the battery has died. They are super comfortable to wear. I sleep on my side and they don't bother me in the least bit. All in all I am very happy with them.

Muy buena mejora respecto al modelo anterior A10 *VENTAJAS: - Duracion de bateria durante la noche total, 8, 9 o 10 horas sin problema con el audio pregrabado en los mismos auriculares - No molestan como unos auriculares "habituales" pero puede que alfgunas personas si, si los comparas con los A10 son algo mas comodos - Aislan bien el audio exterior - La aplicacion permite hacer mezclas de hasta 3 sonidos para reproducir por la noche - Al sacar los auriculares de su caja ya se ponene automaticamente en modo nocturno sin usar ni hacer nada desde el movil, genial si solo los usas para este ambito - Se puede interactuar con control tactil en los mismos auriculares (yo lo desactive) *DESVENTAJAS: - Algo caros si no los encuentras en oferta - Desconozco si duraran en el tiempo, los A10 me fallaron al cabo de 2 años de uso diario

If you’re 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. I’ve worn them all night, even as a side sleeper, and they’re so comfortable I often forget they’re in my ears. The battery life is impressive-easily lasting through the night (and then some), so you don’t 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. There’s 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 don’t need your phone nearby or worry about notifications waking you up. On the downside, I found the touch controls a bit too sensitive-they’d 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 there’s one thing I’d love to see in a future version, it’s active noise cancellation. I know that’s 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 night’s 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.

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.

🌙 Avis – Soundcore Sleep A20 Confortables même en position latérale, ces écouteurs sont parfaits pour dormir avec du son. Bonne autonomie, boîtier pratique, et possibilité de programmer l’arrêt du Bluetooth (mode sommeil) très appréciable. Le son est correct mais un peu plat : léger manque de basses, rendu plus Hi-Fi que Hi-Res. Pas de réduction active du bruit — un choix compréhensible pour préserver le poids, mais parfois regrettable. Les sons intégrés sont variés mais pas toujours de bonne qualité. Le véritable point faible : mémoire trop limitée pour ajouter ses propres sons (environ 1h max). Très bon concept, bien exécuté dans l’ensemble, mais fonctionnalités sonores encore perfectibles.
