Ending today, TechRabbit offers the refurbished Plantronics Backbeat Go Bluetooth Stereo Headset in Black, model no. 86800-01, for $29.99. Coupon code "ATS472VJ" cuts it to $19.99. With free shipping, that's tied with last week's mention as the best price we've seen. (It's also $30 less than the lowest total price we could find for a new one.) These sweat- and moisture-resistant earbuds feature Bluetooth, a 33-foot wireless range, echo cancellation, inline controls, and three cushioned eartips sizes.

A 90-day TechRabbit warranty applies.
