Harman Audio offers the factory-refurbished JBL Micro Wireless Bluetooth Speaker in Pink, model no. JBLMICROWPINK, for $19.99. With free shipping, that's $10 under the lowest total price we could find for a new model, although we saw a refurb for $5 less in May. This portable speaker features a 40mm driver, 150Hz to 20kHz frequency response, bass port, microphone, built in 3.5mm audio cable, and Li-ion rechargeable battery with up to five hours of battery life per charge. A 1-year Harman warranty applies.
