I purchased these based off of reviews that I read and how one reviewer said her sons expensive headset was no better than these, I beg to differ. So, in short, I bought these to go skiing and not have to pop my in ear stereo plugs in and out to hear my surroundings or only wear one ear plug to enjoy my music while still having a conversation or hearing things around me for safety. The final issue that I have experienced is that the fabric holding the strap on my right flip flop broke. Husband wears these daily. There is no static sound, the sound quality is very clear.
