I bought my son his first portable music device 2.5 years ago when he turned 15. In that time I've purchased him about 7 sets of headphones, he and his "friends" have destroyed ever friggin one. He's been without cans for over 4 months now living with ear buds, but I don't like the idea of that long term so I'm asking the following.

1. Is there a dumbass teenager proof set of cans?
2. Does Sennheiser (or anyone else for that matter) make portable cans with detachable wires like my big boy Senns?
3. Can any of the above be had at a reasonable price?

Enquring minds wanna know, thanks in advance....
