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: 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!
*by D***R on 18 October 2024*

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!
