Massdrop offers the MEElectronics Sport-Fi M6 In-Ear Headphones in Black or Clear for $12.99 with free shipping. That's the lowest total price we could find by $5, although we saw them for $2 less in January. These noise-isolating headphones feature memory wire, six sets of ear tips, a frequency response of 20-20kHz, anti-tangle cable, and carrying case. Deal ends March 10.
