KOSS has produced a set of ear buds that has an expandable and contractible system with a metal screw. Just turn the metal screw top on the back of the ear buds, and the tips will adjust to fit your ears.
The estimated price of these earbuds is $150. I think it is a great idea as long as the sound quality is excellent. The Koss CC_01 will be available in March 2009.
