The Lanyard headphones is a kind of all in one system. After plugging the headphones into the iPod’s dock, you can hang it around your neck, plus use the headphones instead of using a seperate pair.
This headphone set retails for $39.99 and is available at Radio Shack for $13.97.
The problem for me is that I have a silicone skin for my Nano that covers the dock, and I prefer not to take it off even to use these headphones which I do consider getting.
