BuyDig offers the Able Planet SH190 Traveler's Choice On-Ear Stereo Headphones in nine colors (Blue pictured) for $9.99 with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (It's a current price low by $10.) Each pair features a detachable cable with inline volume control and 20Hz to 20kHz frequency response.
