Does everyone's earbuds have lower volume coming out from the left side than the right? when i talk or listen to music, the left earbud is barely audible, while the one on the right is as loud as i need it. is this common? will Apple replace them if they are defected? I mean, i bought on iDay, but they've always been like this, but they've finally gotten on my nerves. I'd rahter not pay $35 or however much it is for a new pair, but i don't know if its a defect in my phone's headphone jack or my earbuds.
