Newegg offers the refurbished Creative Active Bluetooth Headphones with Mic, model no. WP-350, for $29.99. This $20 mail-in rebate drops them to $9.99. With free shipping, that's the lowest total price we could find for a refurb by $37. They feature a 18Hz to 22kHz frequency response, Bluetooth 2.1+EDR, up to 33-foot operating range, omni-directional microphone, and rechargeable lithium ion battery. Deal ends March 31.

A 90-day warranty applies, although it's unclear who backs it.
