Dell Home, via its Member Purchase Program, offers the Sony Wireless Headphones in Black, Red, or Blue, model no. MDR-XB650BT, for $78 with free shipping. (Amazon and Abt, among other vendors, charge the same.) That's tied with our expired mention from six days ago and the lowest total price we could find by $2. They weigh 6.7-oz. and feature a microphone, closed cup, and 30mm drivers.
Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
