Bose via eBay offers the refurbished Bose SoundLink On-Ear Bluetooth Headphones in Black for $89.95 with free shipping. That's $10 under our December mention of a new pair and the lowest price we've seen for these headphones in any condition. (It's $70 under the best we could find for new ones today.) These foldable headphones feature up to seven hours of playtime, LED indicators, on-ear controls, a rechargeable lithium-ion battery, and can connect to two devices at once.

Note: A 1-year Bose warranty applies.
