They make a popping sound that hurts my ears when trying to block high pitch noise in noise cancel mode as well as in ambient sound mode at times .. there are times that I wish I never traded my buds 2 in to honest
These are very high quality earbuds, the only issue I have found with them is it is difficult to remove the soft earbud tips and I accidently ripped one trying to remove it, other than that they work well and I think I enjoy them even better than the galaxy buds 2.
They are great sounds amazing still Figuring out all the features only issue I see is a weird sound it makes when your adjusting them in you ear sometimes
