Harman Kardon Official Store via NeweggFlash offers its refurbished Harman Kardon Onyx Studio 2 Wireless Bluetooth Speaker System in Black for $79.99 with free shipping. That's tied with our November refurb mention as the lowest total price we've seen. (It's the best deal for a refurb today by $15, and $59 less than you'd pay for a new one.) It features 15 watts per channel into two 3" woofers and two 3/4" tweeters, a built-in speakerphone, Bluetooth 3.0, 3.5mm auxiliary input, and built-in rechargeable Li-ion battery with up to five hours of play time per charge. Deal ends January 22.
