Skullcandy via eBay offers the Skullcandy Chops Active Grip Hanger Earbud Headphones in White, model no. S4CHCZ-072, for $9.99 with free shipping. That's the lowest total price we could find by $2, although we saw them for $1 less three weeks ago (since expired). They feature 15mm speakers, frequency response of 18Hz to 20kHz, 3.5mm gold-plated plug, and more.
