iPod Mini headphone jack trouble


I had read about this issue a year ago, and like most Mac faithful, I chose to believe that my mini would be ok...and it was since last April. But now my ER-6i heaphones work only on the right side when plugged in to my Mini, and the left side is intermittent. It's kind of driving me crazy. I'm out of warranty on my device, so I'm wondering whether anyone has repaired this trouble on their own or can give me pricing on the repair from Apple.
