Review: 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!
Review: 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.

### ⭐⭐⭐⭐⭐ real customer service!
*by T***T on 4 January 2026*

Excellent tech, excellent customer service. I bought these to listen to things whilst I fall asleep. These are more expensive than others, but well worth it. They are very good quality, do exactly what they're meant to do. Plenty of functionality that can be adapted to your need, good sound quality, very good battery life. Comfy to side sleep on a pillow. 15 months after I'd bought them, and used them every night, one ear pod stopped working. To my surprise, the customer service was responsive, and when it was clear I couldn't fix it, without hesitating they sent me a brand new set. I really hadn't expected a response, let alone a replacement. Very pleased all round
