Best Buy offers the refurbished Beats by Dr. Dre Powerbeats3 Wireless Bluetooth In-Ear Headphones in Flash Blue or White for $84.99 with free shipping. That's $27 under last month's mention, $59 below the price of a new unit, and the lowest we've seen. These sweat- and water-resistant headphones feature Fast Fuel, which gives you one hour of playback with a 5-minute charge. Other features include Class 1 Bluetooth with up to a 300-foot range, dual-driver acoustics, in-line controls, RemoteTalk support, a built-in rechargeable Li-ion battery with up to 12 hours of battery life, secure-fit earhooks, four sizes of eartips, and carrying case.

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