bluetooth peripharal drivers

Those speakers are for using with a bluetooth-enabled mobile phone or iPod/iPhone to play music through the Mitashi speakers so it sounds like a complete hifi stereo system.

They are not for using on a computer.

This is from the Mitashi website describing their bluetooth speaker systems:

"Listening to your favorite songs couldn't be easier, with Mitashi Bluetooth Speakers there's no need of wires. Just connect any Mobile Phone via Bluetooth and Enjoy Music Wirelessly"

For your laptop you need to buy a set of PC speakers, then connect the supplied audio cable's 3.5mm jack-plug to the "speaker out" jack on the side of your laptop.
