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.

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.

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!

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…

Great For Peaceful Sleep
These Soundcore Sleep A20 by Anker Sleep Earbuds are at the time of this review (June 2026) last year’s model, and I got them for less than £80. The newer model has active noise cancelling, but it does cost a lot more. Having used passive earplugs successfully for some time I discovered that a nice wash of pink noise somewhere in the room whilst sleeping actually made my sleep so much better. But my other half doesn’t always want to hear it, and so I thought I’d see if there was a more personal solution. These little marvels are quite something, performing much better than the really cheap option I tried (at around £20). Those began to go faulty within a week of use, with poor bluetooth connection and one earbud simply refusing to charge. No such troubles with the Soundcore A20s. They are incredibly small. So much so that the soft rubber comfort sleeve around the plastic shell has a little tag on it to ensure you can get the buds out of your ear. That design feature alone suggests that a lot of thought has gone into these buds. There are touch sensitive pads on each earbud, and they can be programmed individually to start and stop the music, or to increase and lower volume. Such things are controlled by the very nicely designed companion app, which will pretty much be essential to set up and monitor your buds. Having said that, once the buds were in my ears I found it impossible to get them to respond to my taps. So, I disabled that function. The app contains all kinds of sounds you can download into the earbuds’ own memory, including what they advertise as “AI Brainwave audio”. I didn’t detect any AI or brainwaves. What differentiates the “AI Brainwave Audio” sounds from the other sounds in the app is that all the other sounds are in mono. The “AI Brainwave Audio” sounds are in stereo. One neat feature was the “Personalized White Noise”. Again, something in the naming isn’t quite right, because whilst there are a few white noise sounds there most of them are anything but - being sounds of nature or machinery. The neat part is that you can mix any three of those sounds together. Sadly, although they mix nicely they are all still in mono. The app library also has stories, sounds for meditation, and snore and tinnitus masking sounds. I didn’t use any of those sounds. But I did find a Spotify playlist that gave me ten hours of stereo pink noise, which worked really well. The only real flaw in these A20 sleep earbuds is that they aren’t very loud. I have a number of other earbuds, and the A20s are by far the quietest. You might think that wouldn’t matter, that you would be able to just send more volume to them, but whilst that does seem intuitive you may run into the same problem I did - the dreaded EU regulations on volume limitation. I don’t run into this problem with any of my other earbuds, since they are quite loud enough when the volume on my phone is set below 80%. But the A20s are so quiet that I do have to slide the volume over that limit. This means that half way through the night the volume is automatically reset to 80%. I have woken up wondering where my nice soothing pink noise has gone, only to hear it churning away almost subliminally quietly. If you have young ears (mine are nearly 70) you might not have the same problem for sleep use. But even young ears might have problems using these in any daytime setting. Overall, the whole package, with the puck shaped charging case and the magnetic charging ports inside, is well thought out. The charging case has no screen, so you will need the app. But connection starts as soon as you open the case and remove the earbuds, and connection is quick and painless. I have no reservations about recommending these Soundcore Sleep A20 by Anker Sleep Earbuds to anyone who thinks they might help with sleep. They certainly helped me, and although they were three or four times the cost of the cheaper alternatives I think they offer incredible value for money if you value deep and peaceful sleep. [Just a final few words on fitting the earbuds and getting a good sound. The earbuds come pre-fitted with their medium tips, which may suit you right away. I have big ear canals, and I need the largest tips, but even so I need to make sure they are seated correctly before a good sound is achieved. The instructions provided suggest twisting the earbuds once they are in place, but this is only half the story, and may or may not help seal them in place, depending on your own personal situation. I find it helps to dampen the outer part of the silicon tip before inserting, and push them in quite deep, then pull them out slightly. The silicon tips are very flexible and will grip the ear canal slightly, making them expand to fill the space. It’s essential to get a good seal. If you don’t then the earbuds will sound thin and tinny. You will know the seal is working when your own voice sounds boomy and resonant inside your head. It might take a bit of practice, but it soon becomes second nature and it makes the whole experience so much better. Once in place the earbuds will stay that way all through the night.]

No control over 'Sleep-Mode/White Noise' .....
On the face of it these are EXCELLENT Earbuds ..... Light, great-sounding & comfortalble for sleeping UNTIL HOWEVER they change ON THEIR OWN to 'SLEEP MODE' ........ I wanted these for the music only & no matter how I used the App to cancel/blott-out the 'White Nloise' - after roughly 45 minutes this horrendous noise would actually WAKE ME UP & would need a complete 'RE=BOOT' - that is - I'd have to put the bedroom light back on, place them back in the case & reset whatever device (iPod/phone) I was listening to ...... for it to happen again within the hour !

filled with optimism left sore and very frustrated.
I have been suffering with sleep issues for many years now. I have tried many earplugs with some being better than others. I am a light(ish) sleeper, but the slightest sounds disturb any sleep that I get - others snoring, wind blowing, neighbour’s car doors banging - you name it; it disturbs me. I often fall to sleep listening to a podcast, audiobook or watching some videos with my Sony XM3’s in, but as we all know they fall out, disturb you and then get lost in the bed. Therefore, finding these Anker buds filled me with hope and ticked many boxes – none more than the potential for blocking out sound and being comfortable when I fall to sleep with them in and then being able to leave them in. The added bonus of having some “ambient” background noises to alleviate this also sound appealing. With all of the above in mind, and reading about them on a Telegraph review, I immediately hit the “buy now” button. The fact that these were Anker also made me feel better as they have some brilliant products. And then… What a fall from grace. These on offer (limited time offer) were £99 and oh wow are these things badly overpriced. In my experience they did not block out sound to a decent level – I could still hear general nightly house noises; quilt rustling when my other half was getting into bed, doors shutting and the wind outside. The idea, some of the execution (low profile design, sleep sounds, good battery life and the vast array of attachments) was superb but the fact that they don’t block sound to an appropriate or satisfactory level is totally unacceptable. THIS was the main reason I wanted them. I desperately wanted to block out sound – much more than these do. I actually feel a little cheated – I know I could return them but that just feels like a hassle so they will be consigned to the car or draw as a desperate spare. Maybe I am using them incorrectly, but I followed everything – or so I thought – but £99, no chance. To add insult to injury my right ear keeps swelling whenever I used any of the wingtips/cover but my other ear doesn’t suffer. Obviously this is my fault but I could only ever use one bud! To price these the same as things like Galaxy Buds is rather poor. Sorry Anker, I love your products but these are not great for the purpose intended.

Formidable
Je cherchais des écouteurs avec suffisamment d’autonomie, qui ne fassent pas mal aux oreilles pour la nuit. Après un mois d’utilisation je peux dire que ce produit dépasse largement mes attentes. L’ autonomie : la batterie tient toute la nuit et le boiter ne nécessite qu’une recharge par semaine environ. L’ergonomie est juste extra pour la nuit. L’écouteur extra plat se positionne parfaitement dans l’oreille. Il faut juste prendre le coup de main pour bien l’insérer et après il reste parfaitement en place. Le design du boîtier est lui aussi très sympathique, élégant et dans une matière douce. Enfin le vrai plus qui me paraissait être du gadget, c’est le mode sommeil. On bascule du mode Bluetooth au mode sommeil en tapotant une fois sur l’oreillette. J’ai l’habitude de m’endormir avec des podcasts en Bluetooth et bien évidemment lorsque je me réveille la nuit, j’ai du son dans les oreilles. Là je peux programmer l’appareil pour qu’il s’arrête au bout d’un certain temps avec la minuterie où je bascule en tapotant sur l’oreillette et l’appareil diffuse alors des sons apaisants que je peux même composer moi même. Bref je suis ravie, pour la conception très aboutie de ce produit.

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.

Would recommend and buy again
I have used these headphones every day since I got them. They are comfortable enough to sleep in, which is a priority for me because my husbands snoring keeps me awake. They are easy to use, I love the case. Would replace immediately if I lost them

Ideales para dormir, cómodos y con buena batería
Hago esta reseña viniendo de unos Anker Soundcore A10 (el modelo del año pasado) que si se les podía achacar algo era la poca duración de batería en modo "bluetooth". Sin duda, este nuevo modelo corrige los problemas de la versión anterior. Será inevitable comparar ambos modelos en esta reseña (A10 y A20). Tengo acúfenos (tinnitus) y dormir sin algo que enmascare esos molestos ruidos es bastante complicado. Habiendo pasado por los Bose Sleepbuds, Soundcore A10 y como me ha crecido barba esperando los Ozlo que nunca llegan a Europa (iba a ser mayo, luego se suponía que julio, ahora dicen que a finales de julio), decidí probar estos A20 viendo la buena crítica en cuanto a batería. Llevo algo más de un mes usándolos y creo que es tiempo suficiente para poder opinar sobre ellos. CAJA: Los auriculares vienen en una caja de pequeño tamaño, ideales para llevar de viaje. Se sujetan a la caja magnéticamente. Decir que la forma de colocarse no es la más natural, y los primeros días, cuando te despiertas y los quieres guardar en la caja, no encuentras cómo deben colocarse (entre dormido que estás, no te enteras mucho). Una vez colocados en la caja, se empiezan a cargar. Se puede ver el estado de carga mediante tres led en la parte frontal. La caja en sí se abre deslizándose hacia arriba y en mi caso tiene tendencia a resbalarse de las manos. AURICULARES: Los auriculares son suaves, ligeros, pequeños. Se ajustan perfectamente a cada individuo. El fabricante incluye varias gomas para que a prácticamente todo el mundo le encajen a la perfección. Decir que se incluyen muchos tipos de pad de silicona muy suave y blandita (realmente se nota super esponjosa) y al colocarlas en tus oídos, no notas dolor, presión o nada parecido. Me encanta que casi ni se nota que los llevas puestos. Es posible que haya que combinar un pad de tamaño distinto para cada oído, por lo que recomiendo no precipitarse e ir probando distintas combinaciones hasta encontrar con el indicado. En mi caso, no tuve que hacer ningún cambio y estoy usando los que vienen por defecto. Sin embargo, estuve probando un rato. Como digo, los auriculares son ligeros, mucho. Puedes dormir perfectamente de lado que no sobresalen y no duelen (a veces con el modelo anterior, los A10, me despertaba con algo de dolor y presión). Esto no ocurre con los A20, la silicona es tan suave! MODOS DE USO: Los auriculares tienen dos modos de uso: Bluetooth, para lo que necesitaremos el móvil cerca, y el modo "autónomo" donde no necesitaremos el móvil y los auriculares reproducirán un sonido en bucle mientras los llevemos puestos. En este último modo, el sonido se carga en los auriculares y no necesitaremos el móvil cerca. Además, la batería durará mucho más tiempo. El modo Bluetooth por contra, reproducirá lo que estemos escuchando (música, podcast, ... ). Por contra, este modo reduce bastante la duración de la batería. En este punto quiero decir que si bien el modelo anterior la batería no duraba más de 4 horas en modo Bluetooth, en estos nuevo A20, siempre me despierto y queda alrededor de un 15% de batería (decir que duermo sobre las 7 horas) por lo que creo que alcanzarán unas 8h tranquilamente. Lo escucho a volumen bajo, bastante bajo, lo suficiente para camuflar los sonidos que escucho por culpa de mi tinnitus. Otro punto a tener en cuenta es que la biblioteca de sonidos que se ha incluido, además de ser mucho más amplia (tenemos todo tipo de ruidos: ruido blanco, ruido rosa, sonidos de olas, arpas, ...) son de mucha más calidad. En los A10 era un sonido de 20 segundos que se repetía en bucle y se notaba mucho cuando se terminaba y empezaba de nuevo (lo cual, ponía un poco nervioso dicho sea de paso). En estos A20, lo he probado y los sonidos son más largos y por lo menos en los que he probado, no escucho ese cambio. El modo que uso yo es el Bluetooth. Cada noche escucho Calm, donde hay melodías infinitas o playlists de 8 horas. Según lo que me apetezca, reproduzco una u otra. Voy cambiando, así no me aburro siempre de escuchar lo mismo. APLICACIÓN MÓVIL: La aplicación móvil ha sido rediseñada para estos A20, de manera que es mucho más completa. Mantiene los dos modos que he mencionado antes (Bluetooth y autónomo) pero se han añadido dos cosas: análisis de sueño y playlists para modo autónomo. Empezaré por este último, pues se pueden añadir varios sonidos de los incluidos en la aplicación a modo de playlist. No lo he probado pero he visto que lo permite. Decir que tampoco se pueden subir sonidos nuestros, es decir, si queremos usar este modo, tendremos que usar los sonidos que se incluyen en la aplicación únicamente. Por otro lado, el análisis de sueño (otro más, junto con el del Apple Watch y el RingConn) te indica las horas de sueño, tiempo de sueño profundo, etc. Un detalle curioso es el número de veces que nos damos la vuelta y el porcentaje de tiempo que hemos dormido de cada lado (derecho o izquierdo). No deja de ser curioso.Mediante esta app, también podremos actualizar la firmware de los auriculares cuando haya uno nuevo. En mi caso han llegado 2 actualizaciones. BATERÍA: Aunque lo he comentado antes, una de las cosas que más me ha gustado de estos A20 y que sin duda son una gran mejora respecto del modelo anterior, es la duración de la batería. Ahora puedo escuchar durante toda la noche lo que yo quiera, sin tener que ir a los sonidos incluidos en el dispositivo (y que insisto, han mejorado mucho). Creo que los reviews que he leído que se alcanzan 9 horas con la batería son bastante reales. Es cierto que en los A10, al cabo de unos meses la batería se degradaba con bastante facilidad, veremos qué tal va en estos. Decir también que la caja se carga mediante USB-C (no dispone de carga inalámbrica). CANCELACIÓN DE SONIDO: No, estos auriculares no disponen de cancelación de sonido. Sí que es verdad, que debido al diseño de las almohadillas (pads) puede haber una falsa cancelación de sonido. De hecho, se incluyen algunas almohadillas con un pequeño orificio que deja pasar el sonido, de manera que si tenemos niños, bebés que pueden llamarnos por la noche, los escuchemos (bueno, a priori, porque yo cuando duermo ya se puede caer el mundo). En cualquier caso, el aislamiento es bastante notable. Yo vivo en una calle con bastante tráfico y debajo hay un restaurante y con los auriculares, la melodía y demás, no escucho ni los coches ni la gente al salir del restaurante. VALORACIÓN: Sobresaliente. Creo que hoy por hoy son los auriculares perfectos para dormir. Ya digo que debido a mi problema he pasado por muchas marcas distintas (Hoomband, que como me muevo mucho se mueve la cinta, Bose Sleepbuds que por el precio que tenían acabaron siendo un fracaso a nivel de batería, Anker Sleep A10 que fueron un primer paso para entrar en este mundo y estos A20 que son perfectos). Me arrepiento de haber comprado los Ozlo, que posiblemente sean un muy buen producto pero a nivel de precio, nada que ver con estos A20, y eso que tampoco son baratos. De hecho, un factor negativo de estos A20 es el precio, creo que es algo elevado. Sin embargo, en mi caso, es el precio que hay que pagar para dormir bien y bien invertido está. Sin duda un producto muy recomendable!!

Not disappointed
I was skeptical as unfamiliar with brand, but research suggested they had great features and are comfortable for all night use. They absolutely do everything you would expect from the top names in audio / HiFi. Alarm, sleep timer, auto switch off when detects sleep, tap to change mode or volume. Listen to music, audiobooks or a great selection of sleep promoting noises on the app The flat profile supports side sleeping and range of silicone tips ensures best fit for all night comfort Highly recommended
