I'll let you know if Apple will even replace this.
I'm surprised that this happed since I've only had it for 3 months and didn't even use the headphones for the first month (I use the Touch mostly in the car dock).
This is the first pair of head phones that have failed on me (that I can remember). Even when I commuted into Montreal everyday on the bus and Metro, the (probable) thousands of hours I listed to my other media players not one died.
On the other hand if something was going to fail, I'm sure glad it was the head phones and not the iPod Touch.
UPDATE: Apple wants me to enter my credit card so they'll send me a box. This seems a lot of work for a $10 pair of headphones that I'm sure they won't even replace. Maybe I'll just find an old pair.
UPDATE: Maybe I will send them back. The same headphones are at Best Buy for $50. For $50 they shouldn't fall apart.
