TechRabbit offers the refurbished Plantronics Backbeat Go Bluetooth Stereo Headset in Black, model no. 86800-01, for $29.99. Coupon code "BENBB19" cuts it to $19.99. With free shipping, that's tied with our May mention as the best price we've seen. (It's also the lowest total price we could find for a refurb by $7 and $17 under what you'd pay for a new item.) These sweat- and moisture-resistant earbuds feature Bluetooth, a 33-foot wireless range, echo cancellation, inline controls and microphone, and three cushioned eartips sizes. Deal ends September 2.

A 90-day TechRabbit warranty applies.
