After a very short time these headphones are malfunctioning. It is like I'm pushing the call button so the music stops, the volume goes down to nothing or all the way up. This is the same type of problems I had with my non-waterproof Samsung headphones but they lasted much longer than a couple weeks. The only thing I have used your headphones for is working out at the gym. No water exposure just sweat. Please help me with this problem.
