Title: Remarkable life improvement
Review: I’m actually surprised that I bought these (I got them on sale during Prime Days). Full disclosure – I’m a HUGE fan of Anker products and who knows how many of their products I own (I’ll bet it’s >50). All have been great with one exception – the A10 sleep buds (predecessor to these – the A20’s). Those were terrible and I quickly returned them. So I’m surprised I bought the A20’s. The biggest problem with the A10’s was battery life – they couldn’t get through the night which meant no alarm for wake-up. No problem at all with the A20’s. I had been using noise-cancelling earbuds to sleep with – to block the fan in the bedroom, my wife’s snoring and both of our CPAP machines. These do not use noise cancelling – instead they use noise masking – soothing sounds like rain, crickets, etc. Believe it or not it works. When I put them in I can still easily hear the sounds I’m trying to block (which my Sony WF-1000XM5’s totally block out), but strangely enough after a short while the masking sounds really work and I can easily sleep through the night. Besides the noise masking, the A20’s are way better for actually sleeping than any of my noise-cancelling buds for two more reasons: they are so tiny that i can easily sleep on my side (I’m a flipper) and best of all – they have a built-in alarm. If anyone has tried to use noise-cancelling buds for sleeping, one huge problem is that despite what Apple says, alarms DO NOT work through Bluetooth earbuds, which means you don’t hear the alarm from your phone in the morning. The stronger the noise cancelling, the less chance you’ll hear the alarm from your phone! The A20’s don’t use Bluetooth for the wake-up alarm – it’s in the earbud, so it reliably wakes me up every morning. The net bottom line is that my sleep is quite noticeably improved, which of course is a significant improvement in my life. I’ve written many, many 5 start reviews for Anker products on Amazon, but this one takes the cake – I’m quite grateful to have found these and I CAN’T POSSIBLY RECOMMEND THEM HIGHLY ENOUGH!!!!

Title: A Pleasant Surprise!
Review: Wow, these are really great earbuds! I wore these for 8 straight hours last night and my ears feel just fine, and I’m a side-sleeper. There’s no ache at all in either ear. These are really comfy. Although these came with several different size option in the box, I found the standard size to be just fine for me so I left them as-is. The instructions in the box were easy to follow. Bluetooth pairing occurred without issue on my iPhone 12 and the reception has been perfect. My phone hasn’t been far away though – typically within 2 meters. You can pause/play or increase/decrease volume by tapping on the earbuds and I like that the tap has to be more than just brushing your fingers on the earbuds – it has to be an actual finger tap for it to register – which is a good thing I think because this prevents accidental taps. So far I haven’t once triggered an accidental tap by just touching the earbuds. That’s good design, and that good design is reflected in the rest of this product as well. From the package to the manual to the product itself – it all just feels like quality design. One thing really stood out to me though which was the feel of opening the case – WOW – that is just one heck of a cool case design. You’ll know what I mean when you experience it yourself. It’s funny to say but it really does feel futuristic/sci-fi. Speaking of the case I really like how it has the three charge-level indicator LEDs. I never bothered installing any app for these earbuds because I’m just playing content from my phone (in my case I’m playing a 7.5 hour 3hz binaural beat audio file) and I can tell how charged the earbuds are from the LEDs on the case so I don’t need an app for that. So basically you can use these earbuds just fine without installing any apps. I’m really happy with this purchase.Now I noticed some user reviews reported having failures after a few months so I’ll schedule a calendar appointment for myself to update this review in 6 months to tell you all if it’s still working fine.

Title: Some okay sleep sounds, Decent comfort for side sleeping, Decent features
Review:  I didn’t find any online reviews or videos of the sleep sounds so I attached a video. The attached video basically goes through all the sleep sounds and alarm sounds. The alarm sounds in the vid are played completely (they are like 3 seconds long).TLDR: Decent comfort for sidesleeping minus some rare instances, sleep sound quality varies and is mono but good customization of sleep sounds, good features but lacking a fewComfort:These are pretty comfortable buds for sleeping. If you are sleeping on your back there will be no issues whatsoever. I also found these decently comfortable for side sleeping. Of course, you will still have the feeling of the earbud itself pushing into your ear depending on how firm your pillow is but coming from someone who used the galaxy buds to sleep, these are significantly more comfortable. If you shift your head while side sleeping so that the earbud puts uneven pressure and it puts pressure on some cartilage/skin against the earbud, it may cause some soreness in an area. Ex: On one night a significant part of the weight of my head was put on my antitragus because my head was sliding down which caused some soreness on my antitragus. For me, that occurrence went away for me after a few days of regular wearing or I just got used to it.Battery life:For about an 11 hour sleep with an hour of that being bluetooth audio and the rest being sleep mode on about 50% volume, with no alarm set, I had about 20% battery left on both earbuds. Note that setting an alarm decreases your battery life by 20% according to their FAQSounds:The sounds in the video I believe are in mono. You can’t add your own sleep or alarm sounds. Honestly I wish the sounds were better. Some were good (thunderstorm, rain on tent, storm, train), others sounded like they were low quality and compressed (rain, river, calm stream, shower) as if you were watching a video on low resolution. My favorite sleep sound combo is “Train” + “Hail on Window” which I call the Hogwarts Express. I also wish they had longer and more natural options for the alarm sounds. The alarm sounds are like 3 seconds in length (whatever is shown in the video is their entire length) which just pause then repeat until you turn off the alarm. The sleep sounds are longer (maybe 45 seconds) and just loop. For general sound quality through the earbuds, they are actually quite decent for being used for sleep. They definitely aren’t as good as standard bluetooth earbuds, and they do sound quite sibilant (I used EQ to fix), but I could imagine myself using these as general purpose earbuds.Features:The earbuds have two modes: sleep and bluetooth. Sleep mode plays sleep sounds that are saved onto the buds themselves and bluetooth plays any kind of media through your phone. You can switch between the modes by tapping the earbud or through the app. Sleep mode saves battery. You do have to tap quite hard since the earbuds don’t have capacitive sensors but rely on the force from your finger.Smart switch automatically switches from bluetooth mode to sleep mode when the buds detect that you had fallen asleep. I’m guessing they detect how much you move and if you are still for awhile it automatically switches. According to support, it is based on how much you moved within a 30 minute period. If loe movement is detected within that period, it will switch to sleep mode. There is no way to switch from bluetooth to sleep mode based on a timer which is a big oversight imo. You have to manually switch to sleep mode or rely on the smart switch which I found unreliable sometimes. It will automatically switch even if you are still awake sometimes. But this doesn’t happen often for me.There is a feature where as long as you keep the app running in the background, you can have it automatically adjust your earbuds volume based on how loud the environment is using your phone’s microphones. I have never tried this and I’m unsure on how reliable it is.You can set playback duration so that whatever sound you are playing (sleep sounds/bluetooth) can play all night or play from 0.5hr – 8hrs in 0.5 increments. Ex: If set to 6 hours, after the earbuds detect you are asleep, it will continue to play the audio for 6 hours then stop.You can set an alarm which you do not need to be connected to your phone for it to work. I tested it by setting an alarm, then turning off my phone’s bluetooth. The alarm is able to function without the need for your phone besides initially setting the alarm which is nice. The alarm sounds play for like 3 seconds, pause, then plays the same sound increasing in volume each repeat. After the highest volume, it decreases to a moderate volume and just keeps playing until you turn the alarm off by tapping the earbud. Note that setting an alarm decreases your battery life by 20% as mentioned on their website FAQThe earbuds keep track of sleep data like when you fell asleep, when you woke up, most common sleeping position, times you rolled over, and periods when you were awake, in light, or in deep sleep based on the movement of the buds. I don’t think the tracking is entirely accurate but for general info I believe it is close enough.You can create a custom sleep sound using one or more of the provided sleep sounds (shown in vid) in the app. You add up to three sounds, change the volume of each sound, and tune your overall custom sleep sound (basically an EQ but simplified to changing soft,brisk,soothing,bright).Controls are double tap or triple tap the right or left earbud. You can customize each control to be: switching mode to sleep/bluetooth, volume–, volume +, next track, previous track, play/pause, none.The app provides an equalizer with the presets: bass booster, acoustic, rock, pop, classical. It also allows you to make a custom EQ with an 8 band equalizer for controlling 100, 200, 400, 800, 1.6k, 3.2k, 6.4k, 12.8khz frequencies respectively. You don’t need the app to be open/in the background for EQ to work; it is applied directly and saved onto the earbudsThe app allows you to play a loud tone through both or individual earbuds to help you find them.You can turn on or off the tones for : connecting/pairing, low battery, auto-shutdown, tapYou can turn on or off the voice prompt for: manual mode switchingYou can change the earbuds to default to bluetooth or sleep when taking them out of the case.Issues:The only issue I had was with smart switch. I usually listen to an audiobook with a timer for 30 minutes or so. I wake up with the earbuds in sleep mode, but often with the sleep sounds paused. I have enabled smart switch, set playback to “all night”, disabled touch controls, and have tried factory resetting the earbuds. I have contacted support and am still trying to troubleshoot it. Smart switch did work for the first few days so I am so confused on how it could possibly stop working.Update:I have contacted support and they responded very quickly (in a day or so). So my issue isn’t some mistake or anything, but is intended behavior. If you have smart switch enabled but your Bluetooth audio pauses before the earbuds switches to sleep mode, the earbud will later on switch to sleep mode but not play sleep audio. This actually makes a lot of sense since you wouldn’t want to go from Bluetooth mode WITHOUT audio to sleep mode WITH audio as it would wake you up. If your bluetooth audio is NOT paused when the earbud switches mode, then the earbuds will play sleep sounds in sleep mode. So my solution was to just remove the timer on my audiobook and instead let the earbud pause my audiobook when it switches to sleep mode. Props to Anker support.

Review: I recently purchased these because I got a new and very noise next door neighbour who is up at all hours. I am a light sleeper so heavy walking and cupboards slamming wake me up. I was desperate for a good nights sleep and after much research I came across the Soundcore A20s. I wanted something with built in white noise sound options (the Bluetooth is also excellent but I mainly wanted these for the white noise)Upon receiving them the set up was super quick and easy. There are many white noise sounds built into the app already for you to choose from..I also didn’t realize you can layer up to three of the white noise sounds to sort of create your perfect “noise” and upload it to the ear buds. This was SUCH a cool added feature I didn’t know about.After easily fitting the smaller ear tip and wing tips on, I tried them out. They lasted all night, fit snuggly in my ears and I slept soundly for the first time in awhile. The charge lasted all night and I was still at 60% batter in the morning. The ONLY downside I’ve found so far is when I would sleep on my side, the earbud would dislodge a bit and I could t hear much out of that ear- but the white noise was still powerful enough that I slept through any noise my neighbour would make.I highly recommend purchasing these!

Review: Na geslapen te hebben met de bose Sleep buds en Philips Kokoon zijn deze net zo comfortabel als de bose, maar veel veelzijdiger door bluetooth.Echt een super product, wat helaas nergens de aandacht krijgt wat het verdient.Als je naar oortjes zoekt om mee te slapen is dit de enige juiste keuze momenteel.

Review: Ich muss sagen, ich habe hier etwas gefunden, von dem ich nicht wusste, dass ich es brauche, aber es nun nicht mehr missen will.Ich habe die Soundcore Sleep A20 Schlaf-Earbuds von Anker nun ausgiebig getestet und bin insgesamt sehr zufrieden. Diese Kopfhörer sind die ersten, die ich beim Schlafen im Ohr tragen kann, ohne dabei Schmerzen zu verspüren oder Probleme mit meinem Mittelohr zu haben. Bei anderen ging entweder das eine, oder das andere.Die Klangqualität ist gut, aber wie zu erwarten, nicht auf audiophilem Niveau. Für den Preis von etwa 150 Euro und die kompakte Größe sind die Soundcore Sleep A20 jedoch durchaus empfehlenswert. Die vorinstallierten Natur- und Weißrauschgeräusche sind entspannend und helfen beim Einschlafen, auch wenn die Qualität besser sein könnte​​. Eigene Sounds hinzufügen wäre auch eine tolle Ergänzung, auch wenn die vorhandenen mehr als ausreichend sind.Die Akkulaufzeit ist beeindruckend. Ich kann die Earbuds die ganze Nacht über verwenden und sie halten zuverlässig durch. Ein zusätzlicher Pluspunkt ist die Funktion, dass die Earbuds im Schlafmodus nahtlos von Bluetooth (z.B. einem Hörbuch oder) auf entspannende Geräusche wechseln können, die auf den Kopfhörern gespeichert sind und das sogar von allein je nach Einstellung​​. Das heißt Bluetooth läuft nicht die ganze Nacht durch, sondern nur bis man schläft. Klasse finde ich auch das Schlaftracking. Der Zeitpunkt des Einschlafens wird nicht allzu gut erkannt, die Phasen an sich aber dafür ausgezeichnet und am interessantesten finde ich die Auswertung, wie lange man in welche Position geschlafen hat. Der eingebaute Wecker ist komplett underrated und genial, wenn man die Person nebenan nicht mit wecken will. Diese Funktion sollte mehr hervorgehoben werden.Ein Bereich, in dem ich Verbesserungspotenzial sehe, ist die Größe der mitgelieferten Wingtips. Obwohl die aktuellen Größen gut passen, könnten größere Wingtips für Menschen mit größeren Ohren von Vorteil sein. Für zukünftige Versionen wäre es auch wünschenswert, wenn man eigene Sounds hinzufügen könnte. Eine aktive Geräuschunterdrückung (ANC) wäre ebenfalls ein tolles Feature, auch wenn ich verstehe, dass dies bei der aktuellen Größe eine Herausforderung darstellt.Abschließend kann ich sagen, dass ich von Anker und ihrem Kundensupport erneut beeindruckt bin. Zu einem Preis von etwa 150 Euro bieten die Soundcore Sleep A20 ein hervorragendes Preis-Leistungs-Verhältnis. Wer nach komfortablen und effektiven Schlaf-Earbuds sucht, wird hier fündig​​.

Review: 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!!
