Walmart offers the iLive Wireless Bluetooth Headphones in Matte Black, model no. iAHB64MB, for $18.93. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to dodge the $5.97 shipping charge. That's the lowest price we could find today by $8, although we saw them in another color for $2 less in November. They feature a built-in microphone, on-board volume controls, 3.5mm auxiliary jack, built-in rechargeable Li-ion battery with up to eight hours of play time per charge, adjustable headband, cushioned ear pads, and carrying pouch.
