Hi, Ever since I got the iPhone 6, the left earpod of my headphones has gradually decreased in overall volume, until the point where I can only hear sound coming out of it when i'm surrounded by silence. The right bud is fine. Has anyone else had this problem? Also when this happens, the headphone always feels different sitting in my ear. This is really frustrating; I've gotten the iPhone 5, 5s, and now 6 (the phones that shipped with the new earpods) and this has happened with the 5s headphones, but not to this extent. I'm pretty meticulous with how I treat my electronics so I can't for the life of me figure out why my headphones keep breaking. The only thing I can think of is that I have hair over my ear, and I work out 6 days a week and I sweat a lot and the sweat makes my headphones wet, but I don't only sweat on my left side, I sweat on both sides and the right ear pod has never given me any issue despite getting wet from sweat. I'd appreciate any input if anyone knows how to remedy this situation.
