Newegg offers the JBL Wireless Bluetooth On-Ear Headphones in Black/Blue, or White, model no. J56BT, for $49.95 with free shipping. That's tied with our expired mention from two days ago and the lowest total price we've seen. (It's a current low by $50.) They feature a 20Hz to 20kHz frequency response, 40mm drivers, in-line remote and microphone controls, Bluetooth, and user controls on the outer ear-cup.
