Sleep A20 | Next-Level Sleep Earbuds with Enhanced Comfort

Very happy with these earbuds. I was skeptical that they would work, my ear canals are quite small and so typical earbuds hurt after a short amount of time. But these fit really well after I adjusted the size.

Reliable brand+ Premium build quality and sleek design+ Very comfortable fit with secure ear support+ Includes multiple ear tip sizes for customization+ App is feature-rich+ Sleep Mode works offline—no EMF or battery drain overnight+ Decent sound quality for casual listening+ Great battery life, especially in Sleep Mode– Price is on the higher side compared to similar-function models– No active noise cancellation or built-in microphone (not suitable for calls)– App could be a bit confusing at first– Case could use an internal LED, which would help in low light_____I trust Anker as a brand—I already use a few of their products—so I expected a well-made, polished item, especially at this price. First impressions? Solid. This met my expectations.Use caseThis is a bit of a niche product. You can use it like regular earbuds—at home, on the commute, at work—but know this: there's no noise cancelling and no built-in microphone. So, no phone calls or voice assistants.That works for me. I use earbuds mainly for music and audiobooks, not talking. I can tap my screen when needed.Design & build qualityThese feel premium: high-quality materials, sleek finishing, and attention to detail. Even the case looks and feels great.(A small note to the manufacturers: consider adding a tiny LED inside the case to make it easier to handle in the dark. It would be a thoughtful touch, especially for a product intended for nighttime use.)Comfort & fitEarbuds like this usually fall out of my ears—but these don’t. The small silicone crescent helps keep them in place. Big win for me. They’re soft, light, and come with a full set of tips for different ear sizes. I can wear them for hours comfortably.The appThe companion app (174MB from Google Play) is polished and easy to use. It lets you check battery levels for each bud—which is helpful if you’re a side sleeper using just one. You also get a built-in soundscape feature to help you sleep—calming audio backgrounds like ocean waves or forest sounds. Not a huge selection, but enough.There's an “AI Brainwave Mode” with three themes (Ocean, Stars, Forest). I’m not sure how different it is from the standard mode, but once you find what works for you, it’s effective.Firmware updates are supported too (I received one just before writing this review).Sleep mode & EMF concernsI was initially concerned about EMF exposure while sleeping, but Sleep Mode lets you preload up to four soundscapes onto the earbuds. No Bluetooth or Wi-Fi needed. That’s a great feature—saves battery and reduces EMF.Sound qualitySound is good—not audiophile level, but perfectly fine for music, podcasts, and audiobooks. It suits the intended use well.Battery lifeBattery life is excellent. If you play audio all night, it’ll last—especially in Sleep Mode. But honestly, most people won’t need that. You can set a timer or use the sleep-detection feature (not sure how that works exactly). Either way, it’s efficient.ValueThis is a quality product from a trusted brand—but it's not cheap. You can find similar functionality for less, but you might be giving up build quality and durability. I’d deduct half a star for the price, but overall, I’m happy.Final verdict: 4.5 starsGreat for sleep and focused listening, premium design, and solid app features. Just a bit pricey for what it offers—but it delivers.

Really love it and happy that I finally found a comfortable and durable side sleep earbud! Sound is great. Easy to pair. If you are a side sleeper you will find that first couple of times you wear, it will feel a bit strange but then you get used to it and you forget you are wearing it. It comes with several sizes of silicone fittings both noise canceling and regular, and stay in all night. I use it most for guided sleep meditations and also on airplanes because of noise canceling. Battery life is great!

Super comfortable and with long battery life. I appreciate the additional covers in various sizes. I'm a side sleeper and these are the best I've tried.
