Walmart offers the MEE audio M9 Bluetooth Wireless In-Ear Headphones, model no. EP-M9B-BK-MEE, for $13.99. Opt for in-store pickup to dodge the $5.99 shipping charge. That's a buck under our mention from three weeks ago and the lowest price we could find by $1. They feature a built-in microphone and controls, four sets of eartips, Bluetooth 4.0, and noise cancellation.
