Hello!
I broke my clip+ so the left audi channel kept disconnecting.
after a while i had enough and pried open the back part of the player (quite easy)
thats what it looked like inside
then i noticed that the jack is pretty solid and connects to the plugs tip pretty well.
instead one of the 3 soldered connections had came loose
Oh, and remove micro st card before opening it up (if u feel like u need to do the same thing)
