Review: Great for sleeping and outstanding customer service. - I bought these to help me sleep. I listen to audio books to keep my mind focused and drift off. My mind tends to wander at night and I find these fit comfortably in my ears and let me sleep on my side without any issues. I keep these in all night without discomfort. Battery life is good for the while night 10+ hours when listening to books at low volume. Sound quality is good for voice but these are probably not the best choice for audiophiles. 14 months after I bought these, the left ear bud would not charge past 50%. Soundcore's customer service was outstanding. I sent them an email and they got back to me withing 24 hours with some troubleshooting steps. Unfortunately, they didn't work. However, I called them and was on hold for 10 minutes before I just left a call back number. They called me back in about an hour. Erin, the customer service rep was awesome. She was well spoken, patient, and knowledgeable on the product. She went through the email troubleshooting tips to make sure I did all the steps. After answering a few questions, they replaced the ear buds and even paid for shipping.
Review: Dead battery life. - Pros: The fit. If you are a side sleeper, these are it. They are slim enough that you won't feel much pressure, if any while sleeping on your side. They also fit tightly so that within itself creates another barrier for sound to get in. There is also an array of tips that will not in larger or smaller ears. Sound quality. I didn't buy them for sound quality but got it anyways. Sounds just like any other soundcore buds. Charging case. Magnetic with the open USB C. I love how easy it is to charge these things. Cons: Battery life. At first, the battery life was as advertised. I could sleep longer than 8 hours and would wake up to sound still playing. 5 months in and the R bud does after about 5 hours while the L goes for about 7. That's 4-5 hours gone and it's not even 6 months. I had a feeling this would happen as a few of the soundcore products that I have, have this very issue. I was hoping that for the amount they were charging this wouldn't have been an issue at this stage of their usage but here we are. This is the only con I have but it is the biggest one as this is the reason why I bought these in the first place. 1 year or 2 years in with declining battery life would have been ok but dropping half the life in a few months. Not worth it. I also don't have that much hope for future iterations as I have said, soundcore products lose battery life quickly. Update: Down to 1 star. The L bud died today and it was the one that was holding the battery. The R bud is still losing battery. Its now down to about 4 hours. Lastly, the case is barley holding a charge. I charged them overnight after the case was down to about 30% and it was at 20% after charging them for a few hours. These buds are now completely unusable and I had these for less than one year (bought in Oct 2024). Update 11/13/2025 Soundcore reached out to me and because I was within the warranty period, sent me a new pair. The new pair is the same story. After a few months, the R buds have significantly lost battery sufficiency. I get maybe 4-5 hours with them and sometimes they only charge to 90%. The L buds haven't lost the battery life like the R but there is noticeable reduction in battery life about 1-2 hours. This again is after approx 4 months with the new pair. These are not worth $180. The only thing that is still a pro for these buds is the fit. They still fit in the ear well and rarely fall out while sleeping. The app has been updated quite a bit and is much better than when I first got these buds.

### ⭐⭐⭐⭐ Improved my sleep. Amazing. Bose QC user
*by E***Y on April 17, 2025*

- Noise Cancellation - Coming from Bose QC earbud I thought it’ll be hard to impress me with the quality Bose has provided especially when Bose’s famous for noise cancellation. However, I find that this soundcore earbuds can provide me with the same level of noise canceling with Bose’s only with slightly differences. I experienced loud high pitch noise a lot as I have a young child at home, I noticed they both can cancel loud deeper noises fine but having a hard time with high pitch noises but they way they handle those noises are different. Bose seems to ‘lower the volume’ of the noises they can’t block while Soundcore seems to make the sounds seem ‘farther away’. Away, the level of cleanliness in sounds that could and could not peak through are about the same. - Comfort - Soundcore really stand out in this area as it’s made for comfort in sleep positions, it has light weight to the point sometimes I forgot I’m wearing it. Problem is… the noise canceling silicones can make your ears sweat and greasy. I find myself often feel uncomfortable and needed to clean my ears often if I wear these earbuds just to filter out the noises during the day or still watching something before sleeping. And the moment I wake up I’d have the urge to clean my ears right away as well. Before I got Soundcore I used to use Bose during sleep. Bose always fell off even with the wings, and they are heavy and make my ears sore. Because they’re kind of bulky I have a hard time sleeping in my comfort position as I’m a side sleeper. And using Bose to help me sleep for a week straight led me to have some bleeding before. - Durable - Material … I heard a review from a YouTuber that the material is soft and can easily be torn. I do agree that the silicone part really feel soft and it might rip apart while changing the sizes, however, I never have a problem with it… I’ve try to be mindful but not too gentle with it and my earbuds are still fine. I never pull the silicones while using them so I never experienced any risks. I’d say they are quite sturdy more than how they feel. Battery … the life of the battery is amazing especially comparing to Bose. I never test if they really do last 50 hours as they claimed but I can use Soundcore earbuds for a few days and nights straight without charging them. While Bose last about 2-3 hrs with noise cancellation mode, Soundcore can last the whole night from before I’m actually sleeping to when I wake up, so I can play my calming noises all night. Charging is quite fast…. Honestly I just never experienced it running out of power at all even I use it quite a lot. Unlike Bose that I feel I constantly need to charge the whole thing daily because of my heavy use. I’d say they both have pros and cons, I still use both of them, especially when going out since you can’t turn off Soundcore’s noise cancellation unless you change the silicone buds but Bose can with just a tap. I prefer using Soundcore’s while I’m at home since they do stay in place better, but then again I still have to take them out and clean my ears and the earbuds often. Bose would be better if I plan to use noise cancellation in short period. And I still use my eye mask with headphones over Soundcore’s earbud sometimes, they don’t stay as good but my ears feel less icky.
