Havent put it to the test yet, but looks like it will hold up and like fact it has protective cover. The light is strait forward. and then it is still at an angle. The microphone is great. So I have had several of this form factor earphones from Sony in the past. I am gonna buy again. Upon unboxing, the charging case was functioning great. Aber ist wohl Gewohnheitssache. Lows and mids are balanced. This is my second purchase of this same style of UGGs from Zappos.
