Q: Can I use these earbuds to listen to my own music or podcasts?
A: Yes, these earbuds have a Bluetooth mode that allows you to stream your own content.
Q: Are these earbuds comfortable for side sleepers?
A: Yes, these earbuds are designed to be comfortable for side sleepers with features like an ergonomic design, ultra-soft material, and an air wing design to distribute pressure evenly.
Q: How do these earbuds help me understand my sleep quality?
A: These earbuds track your sleep positions and duration using a MEMS sensor and a real-time clock to provide insights into your sleep quality.
Q: What is the battery life of these earbuds in sleep mode?
A: In Sleep mode, the earbuds offer up to 14 hours of playtime on a single charge.
Q: How does the smart volume control feature work on these earbuds?
A: The smart volume control adjusts the volume of sleep sounds to mask external noise based on your surroundings.
Q: What does noise cancelling mean?
A: So, these are "noise masking", not "active noise canceling" in-ear earbuds. The noise masking is from the rubber tips making a seal in your ear. Active Noise Canceling (ANC) is a higher-engineered earphone/earbud that uses frequencies to match the sound around you and "cancel" them; that's what you want if traveling on an airplane. These are not those. That said, these are pretty good to block out sounds when you are trying to sleep.
Q: will these block out snoring so I can sleep?
A: The Soundcore Sleep A20 Noise Masking Earbuds are designed to help you sleep better by masking unwanted noises, including snoring. They use advanced noise masking technology to create soothing sounds that can help drown out disruptive noises. However, the effectiveness of blocking out snoring can vary depending on the volume and frequency of the snoring, as well as the specific settings and sounds you choose on the earbuds. If you are a light sleeper or the snoring is particularly loud, the earbuds may not completely eliminate the sound but can significantly reduce its impact, helping you to sleep more comfortably. It's always a good idea to try them out and see how well they work for your specific situation.
A: I sleep on my side and they are pretty comfortable. Comfortable enough to not have them bother me. My Bose SleepBuds might have been a little more comfortable but the Bose had shorter battery life and other issues to the point they discontinued them.

Great for sleep and comfort
These earbuds are a game changer for sleep. They’re soft, comfortable to lie on, and they do a fantastic job of masking outside noises like snoring or traffic without blasting music. The app has a nice variety of sleep sounds, and the battery easily lasts through the night. My only complaint is they aren’t quite as invisible in the ear as I hoped, so side-sleepers might feel them a bit. Still, the comfort and noise masking are miles better than anything else I’ve tried. A solid 4 stars.

Would buy again, only way I sleep next to snorer
Case has nice feel to it. Easy to switch out sizes for squishy wrap, which are very comfortable, choices also nice since my ears are different sizes. Easy to remove from ears with small hands with short nails. They have only came out of my ears while sleeping a couple times. Charge lasts all night, case recharges last me all week. Full recharge is quick, about a couple hours. Sound quality is better than my JBLs, as well as better noise cancelling, and comfort. Options for sounds are great, really like the way it gives you ways to build your sounds, and then offers 3 choices to scroll when not connected to phone- saves battery I presume. The snore-blocking capability is why I really got these, and they do amazing. Snore block/train/rain combo is my go-to. Only a couple slight negatives- when opening case the battery indicator lights are bright, wakes you up a bit (or anyone near you). I've used it as a quick flashlight. Also, it may be just me, but One of my ears is tender to lay on and I have to put my hand propped up around that ear to prevent it from being sore. I even have the smallest wrap on it, so it is probs just my ear.

These have made my nights so much better
I bought these earbuds in July 2025 and it's now January 2026. Since I've now been using these nightly for a good while, figured it was high time for a review. I'm a very light sleeper. I've got a white noise machine in my bedroom, but it wasn't enough to drown out the sounds that tend to wake me up at night (mainly the cats thundering around the house at 3am). I had read/watched several reviews of these before I decided to buy, but had also seen some pre-release chatter about the updated model (the A30). Decided the ANC wasn't something that I really needed and decided to give these a shot. I love them. I hadn't planned to use them every single night, but I have. Every night. Used the app to mix a nice set of pre-loaded audio and I've slept like a baby since July. Well, until... Starting in December or so, I started having issues with my left earbud either not charging randomly or only charging up to 50% and dying halfway through the night. I reached out to Anker support and let them know what was going on. They immediately sent out a new set of earbuds. I'm relieved. Amazing support, as always. I'm happy to have my earbuds back and look forward to many more nights of undisturbed sleep. <3 I can't recommend these enough (but I'll certainly try). ----- Some extra details: Sleep position: Side-sleeper (haven't had any discomfort). Ear size: Pretty small. Normal earbuds tend to hurt, but these don't. Sounds being masked: Cats that run like elephants, a dog that licks himself way too early in the morning, and every annoying sound that you'd encounter at a hotel. Best sleep sound mix: Snore masking 1 + rain + orange noise at 70% volume. Perfection.
