I have two sets of identical earphones. One I use for my ride to work on the trolley, the other I use in my laptop bag.. along with my laptop bag I also have a tv tuner with an external antenna which at the base has a huge magnet to attach to any metal surface. Well, one day I changed out the earphones and when I listened to it, it sounded weak and almost constipated. No full bass, just flattened out sound. I really think the magnet got too close to it. Does anyone know if this is the reason? or how I can fix it? I've gone through two earphones of the same model and at first I thought I got a lemon, but now I think it's the strong magnet.
