Walmart offers the Beats by Dr. Dre Powerbeats3 Bluetooth In-Ear Headphones in several colors (Blue pictured) for $99 with free shipping. That's a buck under our November mention and the best price we've seen for a factory-sealed unit. (It's a low today by a buck.) These sweat- and water-resistant headphones feature dual-driver acoustics, on-board controls and microphone, voice control, Fast Fuel (which provides up to one hour of playback on a five-minute charge), and a rechargeable Li-ion battery with up to 12 hours of playback per charge.
