BuyDig via Rakuten offers the Beats by Dr. Dre BeatsX Bluetooth In-Ear Headphones in Black for $100.99 with free shipping. That's the lowest price we could find by $33, although we saw these for a buck less two weeks ago. They feature a Bluetooth range of up to 98 feet, voice control via RemoteTalk, Fast Fuel (which provides up to two hours of playback on a 5-minute charge), and up to eight hours of playback per charge.
