How to fix headphones without taking it apart
only one side doesn't work but I need help fixing it
depends upon the brand. the really good ones have good replacement by the manufacturer. who made them?
Jiggle the little wire that goes IN to that one side.
might as well buy new ones, there broken.
Instead of fixing them it may be easier to just buy a new pair.
Did they get wet? If so but them in rice and use a hair dryer to dry them out! Hope this helps!
