Hello, The other night my friend dropped my Sony MZ-NH700 on a wooden floor (ouch!) and subsequently i can only get sound out of one side of the headphones. It is definitely not a problem with the headphones themselves as i have tried them with other players and they work fine. It seems as if there is a loose connection somewhere inside, because when i fiddle about with the headphone input i get intermittent sound from both sides, but when it is fully plugged in i only get the right ear working. Does anyone have any idea how i can fix this or where i can get this fixed in london? Any ideas how much it would cost me? Thanks for reading! Cheers!
