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!

Blocks out a fair amount of noise. Lots of customisation options.
I currently live by a train station, which is the main reason as to why I bought these. They fit snuggly in the ears & block out a good amount of sound. You have 2 different modes available, Bluetooth mode - for music playback & sleep mode. The sound is very good. It's clear & not muddy at all. It has a good amount of volume too. In Bluetooth mode you have your standard controls, Play, Pause Volume up & Down. You can customise which earbud performs a separate function. You'll also be able to download a wide range of sounds, that you can then transfer over to the earphones. The option will only appear in Bluetooth mode under the Sounds tab. There's an option for you to mix 3 different sound types, that can then play simultaneously. (You can modify the volume for each particular individual sound) then save it under a name you can easily remember. It would be great if you could add your own custom sounds from the Internet too. But then I can see why you're not due to copyright issues. Once saved, the custom sounds will transfer over to the buds themselves so you won't need to use your phone. In the settings you can specify the amount of time Bluetooth playback carries on for until it automatically switches over. You can also toggle on or off the different Prompt Tones in the settings, which I think more companies should allow this. ( Righthand corner - Cog icon) So you won't get disturbed during your sleep. The Prompt Tones are as follows: Connection Tones Low Battery Auto Shutdown Notification Tap Tone Mode Switch Notification You'll need to download the Soundcore app to make the most of these buds. It can be downloaded from the Android store or Apple store. Pairing is easy, straight out the box, it will automatically pick up your buds when you take them out of the charging case. As far as Battery Life is concerned the case holds 80 hours worth of charge. With a 14 hours continuous playback. (Sleep Mode) In Bluetooth Mode it's 10 hours with 55 hours with the charging case. I've found the performance of these buds to be very good & very reliable & the Bluetooth connection is very stable if it's walking around or running. They stay connected & are not choppy at all. I've been running with them a few times & you don't get that thumping sound like you would with some other buds. Which I am suprised about considering just how deep these go into your ear cannal. They have not once cut out on me during my sleep. Which is the most important thing. They are very comfortable especially for side sleepers such as myself. Due to how small these are, I've found the controls to be a little tricky to use on the first try. (that's why 4 stars instead of 5) for the most part they are indeed very comfortable but I found to get a bit little bit of ear fatigue. But then your ears are not designed to have a foreign object in them for long periods of time. Also I had an earbud spontaneously stop working but Anker customer service were great with regards to sorting out a replacement pair. But besides the two negatives, these are a great pair of buds, if you have trouble sleeping. They perform very well for what they designed for & are cheaper than some other buds which make them a very competitive choice.

Painful and battery dead
So I’ve had these for awhile now, maybe around 1 year or so, of which the charging case only charges to around 70%, in addition to this the left earbud only charges to 50% max while the right earbud charges to around 70%. The earbuds can be very painful after around 20 mins of side sleeping. The copper charger connector on the earbuds dig into the bottom of your inner ear which caused my ear to get a small cut after nighttime use. The removable rubber on each ear bud is too thin and after 3 months you can tell the quality is deteriorating and becoming thinner. You have to really mess with the earbuds to really get a comfortable fit and twist and push it down into your ear, there are multiple size options in the pack but they’re not amazing… amid the quality was thicker / better quality then it would be much better. The sound quality is ok but the touch control can be annoying at times. Overall for the price I wouldn’t bother getting these. Go for the cheaper option.

Pretty solid like set of earphones. Sound quality is decent, battery time not fantastic but not terrible. Super comfy and I can wear them all night long as a side sleeper. The app can be wiggy but maybe I can't use technology. Overall happy so far with purchase

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.

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.

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

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!!
