Patozon via Amazon offers the Mpow Swift Wireless Bluetooth Earbuds in Fluorescence Green for $29.99. Coupon code "5YVLJU3T" drops them to $19.99. Plus, Prime members bag free shipping. (Non-members can spend $35 to bag free shipping; otherwise, shipping adds $6.18.) That's tied with our mention from two weeks ago as the second-lowest total price we've seen. (It's also a current low by $7.) These sweatproof headphones feature Bluetooth 4.0, a microphone, up to five hours talk/play time, and three sizes of eartips.
