Best Buy via eBay offers the refurbished Beats by Dr. Dre Powerbeats3 Wireless Bluetooth In-Ear Headphones in Black for $84.99 with free shipping. That's tied with our May refurb mention and the lowest price we've seen. (It's also $35 under the best price we could find for a new unit today.) 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.

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