Gear XS via eBay offers the SoundLogic Wireless Headphones, model no. WH-6/4685/DP-189, for $12.99 with free shipping. That's tied with a mention from last week and among the least expensive wireless headphones we've seen. Features include a built-in FM radio, wireless transmitter (max range of 100 feet), 3.5mm connection, and more. They require four AAA battteries (not included).
