Harman Kardon is currently offering up refurbished models of the Aura Studio Bluetooth speaker for just $119. This is down from the price of a new model being $399. Typically refurbs are priced around $199 or so, making this a great deal even for a refurbished model. And yes, it does still have a warranty, should anything go wrong with these.
The Aura Studio is a rather interesting looking Bluetooth speaker. It's a clear speaker, that continues Harman Kardon's history of creating unique speakers. This one is not portable, so you will need to keep it plugged in, since there is no built-in battery. There is a built-in microphone, allowing you to make and take calls with the speaker - it also features noise and echo cancellation. Additionally, it features 360-degree sound, so it can really fill the entire room with sound fairly easily. As expected from Harman Kardon as well, it features some rather amazing sounding audio, so if you're an audiophile, this is definitely worth picking up.
Harman Kardon's website is offering up free shipping on the Aura Studio, there is also no taxes here. However, there is a limit of two per person, so you can't buy more than two at a time, unfortunately. The sale does end on November 5th, so if you're looking to pick up a new Bluetooth speaker, now is definitely the time to do so.
