I´ve had the iPod Nano 2nd Gen for about two years now. The standard iPod headphones lasted me a year, but they eventually died of natural causes. I then bought Nike headphones and after a month the left earphone died. I thought nothing of it and went to the store and got my money back. Then i bought some DJ style headphones, and sure enough, my iPod killed them. I noticed the pattern of the left earphone always dying after a month so i tried again with some cheap airplane headphones to make sure and once again, the left earphone died. Ever since then i´ve been using the free airline headphones because i don´t want to sentence to death expensive headphones... Why does this happen? Is it because they weren´t official iPod Nano Headphones? Or is my iPod defect? I just got a new iPhone (1st Gen...). Will this happen here too. Thanks in advance.
