A4C offers the manufacturer-refurbished Plantronics Marque 2 Bluetooth Headset in Black or White, model no. M165, for $14.95 with free shipping. That's a buck under our June mention of a new unit and the lowest total price we've seen for this model. (It's a current low for a refurb by $3.) It features dual microphones, voice-activated call answer function, power-saving mode, and a range of up to 33 feet. Deal expires August 8.
Note, a 90-day A4C warranty applies.
