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!

Best night's sleep in years!
Here's what you need to know... These are the most comfortable buds I've ever used. I wanted to ditch Bluetooth eye blinds and thought I'd take the the plunge in these. They block sound plenty well enough as long as you get the right tips and wings sorted for your ear shape. They last all night as long as your ok to have it switch to the onboard sleep sounds automatically when you fall asleep. Bluetooth will do 8 hours most nights though. The on board sounds are mediocre but with some tweaking will do for while your actually sleeping (I use My Noise app until I fall asleep and let the mediocre sounds take over... You can switch back if you wake up by double tapping one ear). Controls are simple and don't activate when you move around. These stay in your ears all night (although I sometimes take them out in my sleep apparently! LOL). They are fine for side sleeping but softer pillow helps... Mine's a firm pillow so I noticed very light pressure...still fall asleep just fine and ears are fine in the morning. Sound quality is great...IF... You spend some time setting your EQ on your phone properly. I use Samsung sound assistant and create a sound profile on a routine that activates on connecting the buds. Sweet spot is to set the bass high, mids low and a little treble to taste. Take out the 4khz band completely. Charging is super quick but not wireless (for the case). The product feels really premium and the case is lush. Loads of tips and wings including breathable ones. No assistant app functionality or mics... But not needed. Companion app easy to pair and use. I use these for watching movies and they sound just fine... Music is ok too... Maybe not out and about as no ANC. So big win is this... I've never slept better. No more hot, stuffy Bluetooth eye blinds and I'm sleeping right through to my alarm. Worth £99? Minus one star here. For the price I'd expect a wireless charging case and maybe in ear detection. ANC won't fit in buds this small so don't expect it! Would I buy em again if lost... Absolutely.

These are better than my Bose Sleep Buds!
Ok, I wanted to wait a week before writing this review to give the most accurate review I could, I review products a lot for a living but I am not in any way affilliated with this company, it's totally not my niche, anyway, here is my opinion: I have owned 3 pairs of Bose Sleepbuds 2, and I was very sad that they discontinued the range, one pair I purchased directly from the company and the other 2 pairs were for well over the origional cost price due to them being rare now (from private sellers). I became used to wearing them every night so they became a necessity. So, onto these! I was reluctant to order a pair of these due to never owning the product before, I like to stick to brands I am familiar with but I was tired of spending ridiculous amounts of money when my Bose batteries decided to fail (yep, and the right earphone issues). I decided to take the jump and I am extremely impressed! They are very, very similar to what I am used to, comfort, ease of use and battery life. The app is so much better too! So many custom sounds for sleep AND (it's a BIG AND).... You can actually customize many of the sounds! You can literally build your perfect sleep sound! You can select say 3 different sounds and adjust each of those with incredible precision, say you want thunder with rain and a train in the background (for example).... you can tweak the rain volume right down, increase the thunder and have heavy or almost silent rain! It's honestly unreal! The app is easy to use, just connect via Bluetooth initially, then you can play around and add the sounds to the buds. You can also set the buds up in a similar way to the Bose buds so that you do not need to use the app to begin the sounds, just take them out the case and they automatically play the sound you set as a preset, to change the sound, you can set the options to just double tap the left or right ear bud to skip sounds! You can also set the taps to change the volume. As for battery life, absolutely incredible! No issues at all, they play all night and have even had them playing constantly for 10 hours. They charge in the case and I have found a full case charge charges the buds 4-5 times but this will depend on volume and how long they run for. The only issue I had was the hardness of the silicone fittings. You get 3 different sizes to swap and change, I set mine up so they were almost identical to my Bose sizes, but the silicone is much softer so the 1st night or two took some adjusting but now, well, I'm just used to them now. I highly recommend these buds! I would never go back to buying Bose again, even if they came out with a 3rd version, everything about these is a game changer for me! Excellent product! Ooooh, also, if you lose one in the night, there is a FIND ME option in the app!

Expensive waste of money
No instructions (thick guide book included is just a tiny piece of info in every possible language). With extensive help from AI, EVENTUALLY managed to find something like brown noise buried deep in a non intuitive menu. Worked for first couple of hours, then could not get it to work again. Added to the many piles of stuff I have wasted money on over 25 years desperately trying to get peace from severe snoring - the reality is NOTHING works, but this was a waste of more money than most.

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.

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.

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.
