    the sound quality is unacceptable, it’s absolutely amazing and it deserves a solid 5 stars.

    Now, totally quiet!
    I was skeptical but pleasantly surprised. I can now endure my wife’s snoring and have a good night’s sleep.

    For the size and price, the quality of these earbuds is excellent. I am constantly looking for some type of headset I can sleep with. These are perfect. I don’t feel them at all, whether I am lying on my back or on my side. See the picture where I put them next to a penny so you can get a better idea of how small they are.

    These really cancel out the noise! They are soft and fit great in my ear! Not annoying like most ear buds! I could even sleep with them at night! I highly recommend!

    I have small ear canals and it seems like I cant keep any of them in place, especially if they don’t have the drag of the rubber. These are easy to pair, hold a solid charge, and stay in my ear all night until I remove them. The sound is pretty good and they don’t seem to bother others by casting sound outwards like some.

    Bought these cause they were advertised “ for small ears” . Well they still aren’t small enough for me so when I’m laying on my side they are uncomfortable

    So good at actually cancelling the noises. My fiancé and I take turns with our newborn baby in order to try to get some sleep, these helps ensure one of us actually sleeps at a time

    These are quite small and comfortable. I tried to wear them to sleep, but they lose connection easily and wake me up by saying “Now connected” several times during the night.

    I have been using these earbuds for few days now and i’m liking these a lot. Firstly, they fit perfectly and I don’t feel any pain even after wearing for long time. And the Sound quality is great, also liked the waterproof and noise blocking functionality.

    I’m used to wearing Bose Sleepbuds 2, which are discontinued.
    This brand is very comfortable for a side sleeper, and I like that you can use any third party noise apps or music.
    Unfortunately the battery doesn’t last long enough for me. I need constant sound for the entire night, 8 hrs. These last about 5 hrs.

    I’ve been testing the headphones for a week. They are actually small, lying on my side I feel in my ear but there is no pain. The headphones fit perfectly in the ears and do not fall out, which is very convenient. You can safely engage in active sports or dance. They look minimal in the ears, I like it. Good loud sound. The songs sound at a good level, I’m satisfied. The downside is that you can’t go far from the phone, they lose connection. One battery charge does not last all day, but they charge quickly. I’m happy with the purchase, I recommend it
