Harman Audio offers the factory-refurbished Harman Kardon Esquire Bluetooth Speaker, model no. HKESQUIREBLKAM-Z, in Black for $174.99 with free shipping. That's $7 below our mention of a new on from last fall and the best price we've seen in any condition. (It's also $75 less than the best price for a new one.) It features a frequency response of 80Hz to 22kHz, noise cancellation technology, dual drivers, custom tuned microphones, play time of up to eight hours, and three-port power adapter. A 1-year Harman warranty applies.
