The best pair of earbuds for the price!
Better than the earbuds pro! More features, more battery, great bass, set the equalizer to your liking, the NC is not the best but surely is good enough, case charge wirelessly and got a premium feel...i strongly recommended great job by Soundcore.

I have been searching for a long time for wireless earbuds that feel good in my ears for at least 4 hours without irritating my ears. I am so happy with my purchase. They don't bother me at all. The base and sound is way better than some of the most expensive ears buds I have purchased. I will stick with this company for my next purchase. This was an excellent purchase for me.

I like it so far
4.5 for disconnecting from devices halfway through a phone call and loud crackling noises that randomly happen. These work great otherwise… long battery life, sound is good. I was surprised at how well the noise reduction function works! Haven’t done much about figuring out the button functions.
