Koss PortaPro Headphones
These headphones may be more than 23 years old and look decidedly like they were yanked straight off the set of Tron in 1982, but they're affordable and offer excellent sound quality and superior comfort. We say if it ain't broke, don't fix it, but if your PortaPros happen to break, Koss will replace them for free--for life.
Price: $39.31 - $41.77 (check prices)
