Extend your listening pleasure
These headphone extension cables are very useful, I use one for my work computer, it's on the floor under a desk. I run this extension cord from the floor to the desktop, and it gives me plenty of slack so I can even lean back and put my feet up.
Pros: Inexpensive, but durable, and the music still sounds great.
Cons: You need a 1/8 to 1/4 inch adapter if you want to use it with some equipment.
