A possible price mistake, Harman Kardon via Newegg offers the factory-refurbished Harman Kardon Esquire Portable Wireless Speaker in Black for $29.99 with free shipping. That's $40 under our mention of a refurb from last month and the lowest total price we've seen. (It's also $157 under the best price we could find for a new unit.) This 2-way speaker features Bluetooth, NFC, dual microphones, and 8-hour battery charge. A 30-day Harman Audio warranty applies. Deal ends April 2.
