Newegg offers the MEElectronics Sound-Isolating Earphones in Black, model no. EP-M9-BK-FF, for $5.99 plus 99 cents for shipping. That's a buck below our fall mention and the lowest total price we could find by $3. They feature 9mm drivers, 95 dB sensitivity, a frequency response of 20Hz to 20kHz, and four sets of eartips.
