One earphone louder than other?

Question

my right earphone for my ipod nano video is louder than my left one. why is that?

also, is it true that the sounds differ from the right and left earphone? for example, the right one emits music louder, and left emits singing louder or something like that?

Answer 1

It can be all that, but one very likely solution is that there is wax build up in one of the earphones.

Just rinse it throughly using warm water and you should be fine.
