These earbuds are very good in sound quality. I like how they fit and when I make a call - my caller indicates that I come through clear. Maybe the only complaint that I have is that the charge doesn't seem to last as long as the previous buds. It's okay though because they do seem to recharge faster than the previous buds.
A stellar upgrade over the buds 2 pro. The sound.... it's just... Amazing! Great fit & I like the touch & voice controls. Samsung did a good job. I just wish there were more options with the blade lights.
Overall is a good set of earbuds. The only issue is the high pitch squeal that you hear when you try to adjust the ear buds. This is a known issue that is mentioned in blogs.
