my left channel keeps cutting out... i thought it was my headphones - this is common with sony "street style" headphones after owning for a long time - this is how they die. but i tried brand new headphones and realized that its the device. i should add... when the jack is not moving i get perfect sound. but when it starts to rotate i get static and crackling and in some positions the left channel is completely gone. this can be really annoying when the thing is in your pocket and you're walking around. for now, i can keep readjusting it, but this is a problem. what can i do ? am i screwed? i've had the thing since the first day of release.
