I have a pair of panasonic headphones , the jack had come off due to rough handling..Howver this local repair guy fixed it up with a duplicate jack and chargd me 300 bucks for it..Now the sound qulity is the same however the jack is a little shaky, ie , needs to be adjusted or at times the sound breaks..Now much of a problem but I'd like to know if there is a solution please..Love these phones too much to dispose them off.
