You can even pair multiple devices using multi-speaker pairing mode. It’s a lot like having a DJ you can carry around, only this DJ has a 12-hour battery life and a wireless range of 100 feet. Pair your phone via Bluetooth or the NFC connection point and start playing some tunes. If you get a call, you can even answer or ignore it from the speaker controls.

This is one of those deals that might seem a little too good to be true, but this Altec Rockbox XL is coming in cheaper because it’s Factory Remanufactured. All that means is that the box had been opened before it was sold. Whether it was even removed from the box is unclear and likely unimportant because it was tested and checked to make sure it works exactly as it should.

You may not need to drop $500 on a speaker when you can get one that’s just as good for a fraction of the price. For a limited time, get the Altec Rockbox XL Speaker on sale for $119.99 (Reg. $199).
