Absolutely amazing. A real life saver!
I previously had Bose Sleepbuds 2 which failed and had to be returned for replacement. As I now cannot sleep without white noise to mask external sounds (not block, these are not ANC, but instead they mask sounds by playing white noise to stop your brain from being able focus on other noises) I had to find something to use whilst I waited for my replacement sleepbuds. I took the gamble with these at an offer price of £99 (the Bose sleepbuds are nearly 3x the price). I wasn’t expecting to be blown away by the quality or features, but couldn’t have been more wrong. The A20s are pretty much better than the Bose in almost every single way. The comfort is great. They are ever so slightly bigger than the Bose, but only by a tiny amount and still more than comfortable for side sleeping. Battery life is solid. I get 6-7 hours sleep and use in sleep mode only. In the morning I have at least 50% battery, so even when the battery starts to degrade, I’m still going to be able to get a full night sleep with them. Using in Bluetooth mode might not offer the same amount of battery life, but they offer an auto switch over mode so you can start in Bluetooth mode and then switch to sleep mode after a set amount of time or when they sense you’ve fallen to sleep. The Bluetooth mode is a standout feature compared to the Bose. You can listen to music, podcasts or anything you’d use normal earbuds for, with the added benefit of then having a full sleepbud feature for sleep time. The sound for music and media is not as rounded as a specific earbud, but that’s not what these are to be used for. It’s an added feature that adds versatility and value as to how you can use them. The app is fantastic and has sleep tracking features and reports, alarms and also a whole suite of noise masking sounds. The customisable sounds are also a massive selling point over the Bose sleepbuds. Bose give you their sounds and nothing can be tailored, so you’d better be happy with what you get with the Bose. The A20s allow you to layer up to three sounds, with different volume levels to create a sound that is perfectly customised to your own needs and preferences. I’ve used a couple of different rain sounds layered over a brown noise track that gives a complicated enough sound so my brain can’t focus son external sounds. I find that 40% volume is perfect for falling asleep to, anything else is much too loud, so reviews saying these aren’t loud enough I find very confusing as can’t see how you’d want them very loud. I eventually got the replacement sleepbuds back from Bose, but they have remained sealed in the box as I now can’t go back to them having found these to be a much more superior product in every way. If you’ve had sleepbuds that have failed and, like me, you can’t live without them, the A20s are a solid replacement at a much better price point. Anker have done an amazing job with these and have beaten the market leader at their own game.

Amazing product that can make a huge difference to sleep.
These ear buds are honestly fantastic. I've been hoping to come across something that can perform like these for a few years and after over two weeks of use every night, I can happy say I've very pleased with them. You pair them with your phone and can use them as bluetooth earbuds. Now there are some reviews here that complain about the audio quality but I'd say two things here. First of all, these are intended to be earbuds that help you fall asleep and play to you whilst you're unconcious, so comparing them to audio equipment at 2-4 times the value which has the intended use for daytime listening is just not helpful. Equally, I come from a profession of over a decade of working in TV and whilst these aren't the absolute best sounding earbuds I've ever heard they are more than good enough and far from the worst. So like I said, you can set them up to playback audio, and I have it set to play an audio book or music from my phone (via Audibles or YouTube Music) whilst I go to sleep. The earbuds then detect when I fall asleep and pause the bluetooth source. They then switch to playback of a white noise/soundscape I have saved directly onto the earbuds that I have set to play for the rest of the night. Now there is a HUGE library of sound effects, sound scapes and white noises to choose from, and there's a tool to mix them and create your own soundscape. You can then have up to 4 saved directly to your earbuds at any one time. You can set it to either play the chosen noises for X amount of hours once you've fallen asleep, or you can have it play for the rest of the night (like I do). As this audio is saved on the earbuds and it's not streaming via Bluetooth, once it's switched to this, the battery life lasts for ages. You can also choose to not use the Bluetooth at all and just start the soundscapes immediately when going to bed. I've seen some comments saying people have struggled with the touch controls and I must admit, when I first started using them, I thought the controls were a dud. But it's just a matter of getting used to how to do them, you need to properly tap them with your finger tip, not just touch them. But it works great and since I've learned how to use them, I've not had a problem. It also makes sense. You don't want the controls to be something that could be accidentally pressed while you're sleeping. Speaking of that, I spend most of the night sleeping on my side and that's not been a problem with these at all, they are perfectly comfortable. They also track your sleep, and whilst the sleep tracking isn't quite as accurate as the tracking I get with my Samsung Galaxy Watch 6 Classic, one unique feature is that it tracks what position you're in for the most of the night (left, back, right, front). In the morning it'll let you know what was your preferred position that night and what percentage of the night you spent in that position, and also how often you turned over in the night. The charging case has a USB C cable and charges pretty quickly. I found that it lasted around 9-10 days of use every night (with Bluetooth and then sound scape for the whole night) before I needed to charge the case. There's three little lights in the front and when you put them back in and close it up i the morning it'll light up to let you know how much battery is left in the charger case. But whilst connected to your phone when they are out of the case you can see the battery level for each ear bud in the app, which is also really nicely put together. Oh, also they have a find me feature. So if you do misplace one, you just tap in the app and it'll play a loud noise so you can find it easily They are comfortable and come with three different sizes of noise blocking cups and 3 sizes of inner cups. Honestly, I really can't recommend these enough.

nice at first but not durable at all
It was a fairly good experience at the start but the silicone bits soon started to fall off or get stuck in my ears, which is really annoying. A year and a half later, one earbud hard cover has fallen off and is unusable and the other won't charge above 20%.I only use them to listen to podcasts and fall asleep, so as intended, nothing extreme. Also sleep mode plays horribly loops of sounds, so I never used it. For £100 earbuds, this is shockingly bad. theu were basically good for the bin less than a year after purchase but I couldn't bring myself to throw them away until now.

Many Pros and only 2 Cons!
I've been using these daily for a few weeks now. In the heat wave we had, I had two fans on, one is very loud and wasn't helpful for falling asleep. I tried my Loop earplugs (which are fab) but I like to listen to a podcast when I sleep. After buying an awful set of earphones, I found these. Pros: They are only a touch bigger than my Loop earplugs so easy to sleep with. They come with multiple pieces to adjust the size. The sound quality is really good for sleeping (I have not used them for anything else besides sleep). If you lose one (or both) the app allows you to find it by playing a loud beeping sound. It works very well! They hold charge overnight without issue. I forgot to put them in the case one morning and they were down to about 10% when I went to bed to read. They charged very quickly when I put them in the case and were good for the night. But the best thing about them is the noise cancelling! Do they cancel all noise? If course not, but my goodness, my husband had trouble waking me up one morning when I had no sound playing through them! Cons: The touch function doesn't work. This is why they don't have 5 stars. Sometimes it would be helpful if it worked, but I'm also not convinced I wouldn't accidentally set the controls off while I slept. They sometimes fall out when I'm asleep. That's it. Two cons and multiple pros. They are a little more expensive than I would like, but they will come in super handy during the day when I'm back on night shifts at work. Overall I do recommend them, the noise cancelling is probably my favourite thing about these earphones.

Great quality buds, ear shape will determine their usefulness.
So I will start by saying I have not used other brands of sleep buds. My review will be purely how my experience is with these. Other users may find they work much better. I have been looking for sleep buds for a long time and so finally jumped in when these finally came back in stock. I've slept using headphones for a long time so wanted to try sleep buds to see if it helps me sleep more comfortably. Sound: This point is will say i was actually surprised how good it was. For how small and thin these are they have surprisingly clear and detailed sound. Good enough for general music listening and they can get loud if you push the volume although I wouldn't recommend that. Sound wise these were comparable to soundcores mid to "pro" buds. Battery: Another super good point but to be expected for buds meant to last all night. No complaints and the case holds many charges before needing to be plugged in. One sad point is no wireless charging on the case. Minor things. Comfort: This is where for me I had to give it up. While they are light and soft when wearing, I had two specific issues. Number one was the ear tips, they are weird for me. They don't seal in my ear nor do they go into the ear canal. They are designed to sit against similar to how the airpods pro work compared to standard ear tips on buds. The issue is the shape. They are way to long in one direction while being narrow in the other. It never makes a seal in your ear, tried multiple tips and wings and could not find a combination that worked. This along with the second issue which was the shape of the buds. They sit at a slight angle and so without the tips holding on the only thing holding them in for me was the wing which meant I had to really twist them in almost painfully to stop them moving about. If you don't move around while sleeping these issues wouldn't matter but if like me you move a lot in your sleep you may find yourself waking up often to these being somewhere under you in the bed. And they are hard to find trust me. It's really hit or miss and depends on the shape of your ear. I tried it and sadly it wasn't fit for me. Other than the comfort I have no complaints on the features and functionality of these. No weird issues, app worked fine, paired and connected seamlessly.

Ultimately disappointing
These are great in so many respects. Super comfortable to wear, generally, although like some other reviewers I did find these caused itching sometimes. But I’ve persevered with them for eighteen months since the tech is otherwise so good. And there’s the problem. The battery life (buds and charging case) is now unacceptably poor. I can leave them charging all day and still find one or both buds have only 10% or 20% charge, not even lasting 20 minutes. For this price that’s not good enough, and not is the difficulty of buying replacement tips. I would love to buy the upgraded A30s but unless I see them at half price or less there is no chance given the problems with these ones. Edit: have now also had a tip detach and get stuck deep in my ear. Beware…. Further update: 27 months from purchase and now the main cover of the right earbud has detached (glue failure) exposing the circuitry. These have not been mistreated. Not remotely durable.

Overall, way better than the Bose Sleepbuds II that these replaced! I love them!
I had a pair of Bose Sleepbuds (MKII) for 2 years and loved them for getting a good night sleep, and not getting disturbed by noise. When Bose discontinued them, and my first pair of Sleepbuds died (battery issues), I was gutted as I assumed I wouldn't be able to find a decent replacement. Then I discovered these, and I absolutely love them. They are WAY better than the Bose Sleepbuds in my opinion for an number of reasons: 1. They will work as a normal blue tooth pair of earbuds, and they actually sound great! I often use them for workouts and the likes. 2. The battery life is loads better than the Bose sleep buds for overnight use in sleep mode. 3. The sleep sounds are much more customisable and you can layer different sounds on top of each other to create a custom sleep sound. The flexibility is fantastic. 4. They cost less than half the price of what the Bose Sleepbuds were, but are a lot more feature rich. 5. The carry/charging case isn't unnecessarily huge like the Bose Sleepbuds. It's also nice and light. In addition, the battery life of the case is also much better than the Bose and I can generally get 5-6 nights out of a single case charge before having to recharge the case. (That's with wearing the buds all night long each night) 6. The way the buds go back into the charger case is a better design than the Bose, and I've never had the buds fail to make proper contact with the case (a issue I had regularly with the Bose). 7. The passive noise cancellation (without masking) is much better than the Bose and even with no masking, they do a great job of blocking out the noise. 8. They are more comfortable to wear at night than the Bose. I did get use to the Bose, but these, I forget are even in my ears, and I'm a side sleeper! The ONLY one negative I can report is the "wing" retention system just isn't quite as good as the Bose sleep buds, and sometimes they feel a little loose despite having the largest fitments installed. However I've never had one fall out overnight, it's more they sometimes unseat themselves and I need to reposition them for a better seal against my ear canal. However this is likely a product of my ear shape and the product design, and with all the other positives, I can definitely live with this and have found a position that minimises this problem. Apart from that one minor point, these are absolutely perfect. I love them and take them everywhere with me when I travel. If you're a post-Bose Sleepbud user like myself, I can highly recommend these as a replacement, or more to the point, an upgrade. Full marks to Anker for their engineering on these. They have done a stellar job!

Better sleep when needed.
I have been using these for a while now and find them a godsend. I am a light sleeper and am one of those people who need a very dark room and quiet to sleep. I bought these initially for when I return to my parents to try to reduce sleep disturbances (people getting up in night etc) and now I am using them to help reduce external noise (traffic etc when windows are open in hot weather). They work well. They are easy to use. Fit comfortably and as I side sleeper I can wear most of the night without too much difficulty. The app in my opinion is good. The fact that you can start with music or audible and when the buds sense you have fallen asleep it switches to the background noise in the soundcore app that you have selected. The noise cancellation is only partially (but I didn’t buy them for this). The battery life is excellent too and you can ‘ping’ the earbud if it’s been misplaced via the app. I have had a couple of times when the app has been problematic, but for the most part I use with incident. They are my most expensive pair of earbuds (and I managed to get them on a Black Friday deal) but a decent nights sleep is priceless so I think it’s money well spent!

Geweldige nachtrust!
Geweldig principe: een plug in je oor die het omgevings geluid dempt, plus een extra (zacht, instelbaar) geluid naar keuze om het omgevings geluid nog beter te dempen. Eerst wat wennen tijdens het slapen, doch de oordop is echt heel erg plat, zodat je prima op je zij kan slapen. Heel veel extra siliconen dopjes in verschillende maten meegeleverd om de passing in het oor perfect te maken. Er kan zowel een vooraf geladen geluid worden afgepeeld (ruis/regen/zee.etc., via de app te installeren), maar ook bijv. een luisterboek worden afgespeeld. En, wat voor mij de doorslag gaf, via de app is er ook een alarm in te stellen, want de reguliere alarm klok hoor je natuurlijk niet meer... Tot slot: helaas na een maand of 2 trad er een probleem op, dit is echter door de fabrikant, die meteen reageerde op al mijn emails, naar volle tevredenheid opgelost! Chapeau!

Underbara!!!!
Jag älskar dem! Har använt dem i ca två månader nu och vilken förändring för mitt välbefinnande. Bor vid en plats där folk ofta festar på nätterna på sommaren och min man snarkar som ett sågverk. För första gången på länge väcks jag inte av fest, musik eller makens snarkningar. Jag har läst något om att det ska komma några med brusreducering och de är jag väldigt sugen på att pröva. De är inte de jag använder för att lyssna på musik och de fungerar inte för att prata i telefon, men för att få hjälp med sömnen är de enastående!

Słuchawki przerosły moje oczekiwania
W tych słuchawkach można naprawdę wygodnie leżeć na boku. Nie spodziewałem się tego, mimo obejrzanych przeze mnie recenzji, bo nawet małe zatyczki do uszu, które posiadam, wywierają presję na ucho. Tutaj prawie tego nie ma. Wreszcie mogę wygodnie słuchać audiobooków przed snem! W zestawie, oprócz standardowych gumek, są też takie przepuszczające powietrze (i dźwięk). Te są nawet wygodniejsze od tych tradycyjnych, chociaż dźwięk traci nieco na jakości (jest o wiele mniej basu). Do podcastów czy audiobooków jednak basy nie są aż tak potrzebne, liczy się wygoda. :) Gęsty stuknięciami w słuchawkę są bardzo przydatne, choć trzeba się do nich trochę przyzwyczaić (musiałem się nauczyć w nie stukać mocniej niż się spodziewałem). Ogółem, jestem bardzo zadowolony z zakupu i polecam te słuchawki każdemu, kto lubi sobie czegoś posłuchać przed snem.
