Skullcandy via eBay offers the Skullcandy Jib In-Ear Earbuds in eight colors (Blue pictured) for $4.95 with free shipping. That's the lowest total price we could find by $8, although we saw them for free via Staples Rewards in December. They feature 10mm drivers, a frequency response of 20Hz to 20kHz, 3.5mm plug, and more.

Of note, these headphones are new, but the packaging may have small scratches or dents.
