Big Deals via eBay offers the open-box Motorola Motorokr S305 Bluetooth Stereo Headphones, model no. 89335N, for $15.99 with free shipping. That's tied with our mention from a month ago and $7 under the lowest total price we could find for a sealed unit. These wireless headphones feature a range of up to 33 feet, built-in microphone, on-ear controls, up to 6.5 hours talk time, up to four days standby time, compatibility with most Bluetooth devices, and 30mm speakers.

Note that they may be missing the original packaging or be in the original packaging unsealed.
