"I've been on a journey for the last month searching for the perfect plugs for side sleeping, and these are the ones for me. I have two dogs that lick their lips throughout the night and it was driving me crazy. It'd wake me up and keep me up multiple times.First I tried foam plugs, and while they cancelled the noise well, they were a pain to get in properly. I needed something that I could just throw in when I get sleepy and immediately fall asleep.I then tried some $20 silicon plugs. These also cancelled the noise, and we're comfortable for a week or two, but my ears started to ache in the morning.I then decided if I'm going through the trouble of finding comfortable plugs, maybe I should invest in them. Having them play audio would be nice, especially alarms, since I'm often at events where I need to wake up before others. I then tried the Soundcore A40. This was a mistake on my part, as these aren't for sleeping. Wouldn't matter if I bought them for their intended purpose, I could not get them in my ears. No matter the tip size, they just wouldn't go in, and I'm not sure how they are supposed to for anyone, as they get really thick really fast, so not much can even fit in your ear. I left a negative review being honest about how I didn't do enough research, but how the product still failed at it's intended use case. I promptly was contacted asking if I'd like a full refund without needing to go through the hassle of returning. I accepted, and kept their excellent customer support in mind.I then tried the Ozlo Sleepbuds. These things are $300 and created by ex-BOSE engineers. BOSE used to have their own sleepbuds, having two generations before being cancelled, and people go on and on about how great they were, so surely the Ozlos would be good... They weren't. They were more comfortable than the cheap plugs, but not by much, and the audio constantly cut out. This is due to them doing Bluetooth from your phone to the case, then the case to the buds using a very low bandwidth and power saving Bluetooth format. This let's them be extremely small, but multiple audio drop outs a minute is unacceptable, so I returned them.Last shot, I went back to Soundcore and got these. They're larger than the Ozlos, but better in everyway for me. They're larger, but that isn't a problem for me since they're more comfortable. Larger also allows a bigger battery. They also don't drop out the audio! For a fraction the price these things beat the Ozlos, which is crazy to me considering how bad of a product I found the A40s to be. Extremely happy with their customer support, and extremely happy with this product."

Let me start by being honest; Amazon's not letting me review the new A30's here…
Let me start by being honest; Amazon's not letting me review the new A30's here but here's my review of both A20's and the new A30's. This is posted on SoundCore's site as well:First a couple of back story statements: Amazon is now not taking reviews of the A30's unless the buds are purchased through them and since I was part of the Early Bird KickStarter and got them directly from SoundCore I couldn't do a review there (where most of the reviews are posted and viewed). It seemed that the majority of reviews on Amazon were from first time SoundCore users. I've had six months of A20 use and the same amount of time communicating with SoundCore's Support Team and Tech Team so I have some viewpoints on that. As a note I was a Bose SleepBud user for three years and experienced all the down sides of their difficulties with battery, range and software glitches that eventually drove them to decide to discontinue the product. Here's my take going from the plus side to the somewhat negative side: For those of us who had good experiences with the A20's the shift to the A30's is far easier than it would be for a first time user. The app layout is similar with some changes that take into account the ANC tech and the ability to store more than one "Land" sleep sound whether white noise or snore blocking. While this seems a little clunky unless you want to continually change sleep sounds night by night I don't see any issue with this. The setup is quite easy as were the A20's and pairing whether using the app or the Bluetooth setting is simple. The app's navigation is similar to the A20's with some needed additions to the Sound Scape variety for pre-sleep. As with the A20's the range of the buds from a phone is excellent so if you have to head to a distant bathroom or elsewhere the long range really helps. The whole reason for switching from the A20's to the A30's was the addition of ANC to the product. The A30 bud is slightly larger than the A20 but certainly still low profile and comfortable and permits side sleeping without issues. The reviews mentioning the lack of sensitivity with the touch adjustments for sound level and switching from Bluetooth to Sleep mode may be due to the need to contact the bud DIRECTLY on the flat face rather than even slightly off center. A big complaint from reviewers on both A20's and A30's is the sudden transition from Bluetooth mode to Sleep mode that's jarring and tends to wake you up with the software detects sleep. I think this is being addressed but is a definite downside for both devices. Again, similar to the A20's. I've communicated some of my concerns about the transition from A20's to A30's directly to SoundCore's teams but my chief complaint is the difficulty in SoundCore's verbiage on the directions for the products. Simple is good and my experience with both the ear buds as well as other SoundCore speakers is that their directions use quite confusing wording and in general need to be far more clear and use simple statements that don't require trying to figure out what the terminology means and what they're intended to do. Finally, I've read reviews that are critical of the ANC function in terms of how much noise the A30's is blocked out. My experience is that the ANC is not nearly as effective as either over the ear cans or competitors' like Bose's noise cancelling but in such a small package that's very comfortable for sleep positions you're not going to fit total ANC in the bud. It does reduce background noise but is certainly not capable of true ANC as of right now. Now for the positive; In the six months I've dealt directly with SoundCore their Support and Tech teams are excellent. In a business that normally does not have the ability to directly contact the manufacturer by phone the Tech team is accessible and very helpful. SoundCore Support is email only but VERY responsive in a short time frame and is very patient and helpful. I know this may seem a side issue but for anyone that's experienced product and setup direction issues being able to get quick responses and tech guidance is a game changer. SoundCore is pushing hard on brands like Bose's product placement and is now in both Verizon stores as well As Costco. With the added customers i'm hoping that the customer service gets expanded and can keep up. I know that SoundCore is working on software updates and some technical tweaks and that should help but right now not sure that switching from the A20's to the much pricier A30's is necessary. For first time SoundCore customers the A30's function well and have some features that make it worth the bucks with the proviso that SoundCore will continue the software and direction improvement.121 people found this helpful

I have been an Anker Soundcore Sleep Earbuds customer since the beginning. I purchased the original A10, then backed the A20 in the Kickstarter and purchased a second pair (for my wife) from Amazon. I also backed and received the A30 on Kickstarter and are using those presently. So, I don't give a review like this one lightly.I got my original A20 earbuds back in May 2024 and the 2nd pair in Jan 2025. Honestly, they are awesome. Sound quality is great, periodic cleaning kept them working well, they mask noise well and the battery life was perfectly fine until....A month or so ago, my A20's got the 1.57 firmware update from Soundcore. I didn't think anything of it at the time, but the right earbud just started refusing to charge above 30%. It would charge from 0% to 30% just fine, indicating it had good contact with the pogo pins. But it simply would not charge over 30%, ever. The left earbud charged perfectly fine to 100% every time.I did some research and it turns out many others are experiencing the same issue, specific to the 1.57 firmware update. Apparently, that firmware has a known issue where it messes up the battery calibration of the right earbud and causes this exact problem.So, in short, Soundcore pushed a firmware update to my A20 earbuds and in the process made them unusable.You might think "Well, they're in the 18 month warranty, just get them replaced". I did reach out to support, and they agreed to replace the earbuds, but what happens when Soundcore pushes out a firmware update that breaks the earbuds when they are just out of warranty?If the warranty is 18 months, and Soundcore can break your device outside of the warranty at any time, this means that the device has an 18 month lifespan. So, if you are going to purchase these be aware that they should be considered disposable and you probably won't get more than 18 months of usage out of them given the above.UPDATE: 2025-12-20Soundcore sent me replacement A20's for the ones that they damaged with their 1.57 firmware update. These new A20 sleep buds came with a much higher revision of the firmware 03.22. So, it looks like the firmware now skips from 1.50 to 03.22, as Soundcore definitely has pulled 1.57 off their servers (since it broke so many customers' A20s).But... the replacement pair Soundcore sent me were defective. The right earbud consistently discharges at more than 2x the left earbud. So for example, after 7 hours of Sleep Mode white noise playback, the left ear bud would be at 70% while the right ear bud was at 30%. I am continuing to see if I can get Soundcore to actually send me a functioning replacement for the sleep buds they broke. We'll see what happens...UPDATE: 2025-12-29Soundcore sent me a second replacement for the defective A20's that they sent as the first replacement for the A20's they bricked with the 1.57 firmware update. So, this is now the third pair of A20s... This pair appears to work correctly, and the right and left earbud discharge battery at the same rate and look like they will achieve 12-14 hours of playback at 50% volume in Sleep Mode. So... after several weeks of back and forth, and multiple pairs of bricked or defective earbuds, it looks like I have a properly working pair again.Support was very helpful about all of this, and I found them receptive to all of the issues I was experiencing, so I don't want to be disparaging of Soundcore support at all here. In general, I've found them good to work with. But... I think the quality control of the Soundcore products is not great. I had battery discharge issues with my original A10 earbuds, and went through a similar replacement dance with those as well. It seems like Soundcore's sleepbuds are prone to battery issues very frequently, since I've now seen issues with uneven battery discharge in 4 separate pairs of A10 and A20 earbuds.My wife's A20 sleepbuds are still on the 1.50 firmware, as the 1.57 firmware has been pulled by Soundcore. I asked support about this and they confirmed that there were multiple hardware revisions of the A20's, and the replacement A20's that I got (which are on the 03.22 firmware) are a later hardware revision than the A20s that were on the 1.50 and 1.57 firmware. Support left it very ambiguous as to whether or not hardware with the 1.50 line of firmware would even continue to get firmware updates, or if that hardware revision has been effectively abandoned by Soundcore. If you are going to purchase these, you need to make sure that the firmware is the 03.22 line, and NOT the 1.50/1.57 line, since that means you have an older revision of the hardware.75 people found this helpful

I abuse earbuds. I wear them all day and all night. I almost always have 1 bud in my ear at any given moment.I bought these buds, the most expensive on my list of compartive options. I was sold on the 14 hour battery life of a single bud and the ergonomic "sleep" design of the bud. As I said, I wear buds all day and I know normal bud designs (not the airpod style) tend to fall out throughout the day as they "lose grip". The design of this bud makes it very secure in your ear. I have worn them all day and I never worry about it falling out.Things I like:- sound is great, and with the app you can customize your sound settings-battery life is amazing (I used to switch buds several times a day now its once, maybe twice if my ear is starting to hurt)-sleep feature is kind of cool, it will also track how much you roll over and which side you are sleeping on. I still only wear one bud at a time while sleeping.-earbud design is very secure (and you get lots of ends and wings to customize earbud sizing, I changed my wings to small)Things I don't like:-comfortablity. I don't like over ear headphones because the pressure causes my ears to hurt. Three days in and the first few days my ear would start getting sore after a few hours of wearing the earbud, so I would just switch buds and be fine. At the end of day three they are starting to feel a bit more comfortable long term so maybe there is a break-in period.-touch controls. While the abilty to choose your touch control settings, the double tap or triple tap is not sensitive enough. They designed it this way so it won't be triggered during sleep, but tapping a bud that is securely in my ear is loud and hurts. I'm getting better at doing the double tap, but I avoid it when I can.-no multipoint bluetooth connection. Despite being the most expensive option on my comparitive list, this was the only one that didn't have multipoint bluetooth.-sleep mode is unnecessary. I get why it is made the way it is, but I think the looped sleep sounds should just be available as bluetooth and just stream from the app. I struggled with the double tap touch controls default setting being switching modes which was inconvenient.Update: It took about a full week for my ears to really adapt to this headphone style. I now find them very lightweight and so comfortable that I almost forget I am wearing it unless I am listening to something.I absolutely love the sound quality and the ability to adjust. I have mine set to acoustic and I really like it.The battery life on these are epic. Several times now I have accidentally left the headphone case on my desk at work and had to rely on the headphone I was wearing the last the "night" (4:30-1AM), and it did, every single time.9/10 would recommend!Sept 2025 update:The battery life is starting to fail. So one earbud gets almost no charge. It can be in the case all day and I'll pull it out and it will be at 20%. Yes the case is charged but the earbud just isn't. The other earbud will last for 4-5 hours still, but nothing like it used to at like 8-10 hours. It sucks that for almost $200 the battery life is nearly depleted after a year of regular use and abuse. I've had $50 earbuds last longer than this.68 people found this helpful

I’ve been using these for over a month, so I now feel like I can give a proper field report about them. I’m highly satisfied overall. For reference, the earbuds I used for sleeping before this were the 1MORE ComfoBuds Mini, and I was highly apprehensive about switching to dedicated sleep buds because it would mean losing active noise cancellation. However, 1MORE seems to have discontinued the ComfoBuds, and since those have pretty severe reliability issues, I decided to take a chance on these Anker buds. I have not regretted it.For starters, they’re very comfortable, and they STAY comfortable. With the ComfoBuds, they’d feel comfortable when I first put them in, but I’d be waking up a couple of hours later wanting to rip them out because of how much my ears hurt…that is, if they hadn’t already fallen out on their own by then. The Ankers feel unobtrusive all night, and I’ve worn them for 7-8 hours sleep sessions and still not woken up with ear pain. Also, they don’t fall out. Like, ever. That’s especially impressive because I move around a lot in my sleep, but never once have I woken up to find them scattered across my bed. Obviously fit is super subjective and everyone’s ears are different, but they worked well for me.Noise isolation is good. I don’t think it’s as amazing as Anker makes it sound, but I’d say that it’s about on par with how the ComfoBuds blocked noise with ANC on (which admittedly wasn’t the world’s strongest ANC). Really, the ace up Anker’s sleeve is the sleep sounds. I’ve used many headphone apps in my time, and Anker’s is by far the best. It’s well-designed and lets you mix your own sleep sounds, which I loved. There’s also sleep tracking and other features. I appreciate that you don’t actually HAVE to use their app — you can just cram the buds in your ears and listen to your usual content or sleep sounds — but I’d recommend it, just because it works really well. The in-app sleep sounds have successfully blocked out snoring, loud conversations, and vacuums when I’ve used them.Sound quality is…meh. But I mean, that’s not really what you buy these for, right? Some sacrifices have to be made for their small size. In this case, the sacrifice is that there’s basically no bass response (I listened to a thunderstorm soundscape and could barely hear the thunder). They’d be fine for podcasts or quiet music, you just wouldn’t want to use them as regular headphones when it’s not bedtime.I’ve had a few minor connectivity issues, mainly regarding one or both earbuds disconnecting when I lay on my side in a certain way. I assume that the pillow is blocking the Bluetooth signal? There’s ways to circumvent this, like putting them in a special sleep mode that doesn’t require Bluetooth, but then you’re restricted to a limited selection of sounds and you can’t use the sleep-tracking function. Usually I can just shift slightly and they’ll reconnect, so it’s annoying, but not a huge deal.TL;DR: These are comfortable, smartly-designed buds that successfully block out disruptive noises as long as you’re playing some kind of sound through them. Sound quality is acceptable, and though they have some minor connectivity issues, it’s not enough to ruin them. I would highly recommend these over using regular earbuds of any kind.48 people found this helpful

UPDATE: After making my original post Anker contacted me and offered a full refund. With the excellent customer service it may be worth the gamble to see if you get good units. I'll probably be back for the A30 Sleep series whenever that's released, I hope those work better.These are great earbuds.... for the first 2-3 months. Truly the best sleep headphones I've ever used. Most of the others are cheap ones from Amazon. The Anker branded sleep headphones were the first ones I found that didn't have a very loud voice yelling in my ear "CONNECTED", "DISCONNECTED", or "POWER OFF" in the middle of the night waking me up. The fact that you can completely disable all sounds on these is great. They're comfortable for me as a side sleeper, but everyone is different, so YMMV.Now the really bad. I've had 2 sets so far, both lasted almost 3 months before the right ear is nearly inaudible. Both sets had the right ear gradually getting quieter and quieter, it's not related to ear wax build up or anything as I've regularly cleaned them and when taking them out of the case the volume is noticeably louder compared to the next morning when it is impossible to hear anything, the only way I know it's still connected is that the touch button still works and the app reports ~80% battery, my audiobook app turns off if I don't shake it every 15 minutes so most of the time I'm asleep within 15 minutes, so these get very little active use and are in standby most of the night.I got my first set replaced with warranty fairly easily, which is really the only reason they get 2*. But for the money these should really last longer than 3 months. The S10's I had before lasted over a year before one of the ears died, which isn't amazing but for that year I had the best sleep I've ever had so the higher price point is worth it, but there's a big difference between the cost being ~30 cents per day to over $2/day before they're not functioning.At this point I don't recommend these, if they worked well for more than a year it would be good but the fact that I've had 2 units fail the exact same way is disappointing. I figured the first time it happened must have been a fluke since very few reviews say anything like this happening, but to have 2 in a row with the exact same problem seems like possibly a manufacturing defect.42 people found this helpful

Finally, I have a set of headphones that I can wear all night. I am a side sleeper and have spent years using different headphones, mainly over the ear. They were uncomfortable, did not mask noise, or broke after a few months of hard sleep. Earplugs did not cut the snoring from my wife and irritated my ears. I also tried noise-canceling headphones and earbuds, including ones from Anker. The noise canceling caused a whistling shriek when lying on your side. Despite some negative feedback in the reviews, I decided to give these a chance, and wow, I am glad I did. They are a little spendy, especially for a Soundcore product, but they are comfortable all night without the irritation from earplugs. The buds come with a bunch of different wings and tips. Be patient and try a few things out before passing the final judgment. Noise-canceling is unnecessary because you can get a good seal to block noise. I use the custom noises downloaded to the buds, which work great. Battery life is outstanding. I have not listened to music with these, but that is not what they are designed for.UPDATE: I stand by my original assessment regarding comfort and the ability to block out a very loud snoring bed partner. HOWEVER....this is the second pair of these earbuds that have lost sound in the left earbud after about six weeks of use. I tried all of the troubleshooting on the SoundCore site: reset, unpair, hard reset, etc., to no avail. I did this for both pairs and had no luck. I have a warranty request for the second pair, so I will see what happens. Knocking off a couple of stars because they are unreliable, especially for what they cost. I expect better.106 people found this helpful
