Review: 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. Review: 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 Β£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. ## Features - A Full Night's Peaceful Sleep: Our exclusive 4-point noise masking system and twin-seal ear tips with 3Γ— stronger passive noise blocking mask snoring, pet sounds, and ambient noise.

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.

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. ## Frequently Bought Together - Soundcore Sleep A20 Earbuds by Anker, Noise Blocking, Comfy for Side Sleepers, AI Brainwave Audio, 80H Playtime, Stream Content via Bluetooth 5.3, Sleep Monitor, Personal Alarm - Loop Quiet 2 Ear Plugs – Ultra-Comfy Reusable Noise-Reducing Earplugs for Sleep, Deep Focus, Travel, Noise Sensitivity | Flexible Hearing Protection | Customizable Fit | 24dB (SNR) Noise Reduction - Mack's Ultra Soft Foam Earplugs, 50 Pair - 33dB Highest NRR, Comfortable Ear Plugs for Sleeping, Snoring, Travel, Concerts, Studying, Loud Noise, Work | Made in USA --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/720290730-soundcore-sleep-a20-earbuds-by-anker-noise-blocking-comfy-side](https://www.desertcart.pl/products/720290730-soundcore-sleep-a20-earbuds-by-anker-noise-blocking-comfy-side) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
