Jawbone’s mini Jambox speakers now have a free new firmware update available online, offering you a gift that keeps on giving.  The new update will allow you to wirelessly connect two speakers together to double up the sound.

All that’s required of you, other than owning a mini Jambox speaker, is to plug in your speaker via USB to your compupter and go to Jawbone.com to install the update. Activating the new feature is as simple as pressing the three buttons on top of the speaker in unison and it will connect to another Jambox within range.

Once connected you can switch from unison mode to stereo mode, which will give you the distinct right and left speaker surround sound experience. The Mini Jambox was originally released in September, and can stream the music from the cloud or your phone to the device.

Travis Bogard, vice president of product management and strategy, said;

“It’s the only speaker that delivers this kind of sound quality for its size, letting you enjoy and share all of your favorite audio wherever you are.”

The speakers usually sell for $179.99 but are currently on sale for $129.99. Check out this video posted to their website to see how easy it is to use.
