Iphone earbuds losing sound on the left side.

I have seen a few other people posting on this issue, but I wanted to see if there was any update on it.

Over the past couple of weeks I had noticed that the left earpiece on my stock iphone earphones was very quiet. So I switched to another set, which eventually had the same issue. At first this really didn't bother me, since I only use them to make calls, instead I use a pair of Shure headphones when I am listening to the ipod function, or any one of my radio apps. However yesterday I plugged in my Shure headphones and now the left earpiece has gone almost silent. So I tried it on my computer, and had the same issue. I also grabbed my iphone headset, and plugged it into my computer, same issue. So it appears that some how my iphone has killed the left earpiece on 3 different headsets. Is anyone else experiencing this issue? Anyone have a solution? Purchasing a new set of Shure headphones isn't really realistic....
