Amazon offers its Amazon Prime members the MEElectronics M9P Hi-Fi Sound-Isolating Headphones in Black (pictured), model no. M9P-BK, or Silver, model no. M9P-SL, for $8.99 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's tied with our mention from two weeks ago and the lowest total price we could find by $6. They feature a 20Hz to 20kHz frequency response, inline microphone, 3.5mm plug, and 4-foot cord.

Note that the silver earbuds are backordered two to three weeks.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months. (There's no longer a waitlist for Amazon Mom.)
