I can't find this cheaper anywhere else but I'm sure somebody else will!
''These portable speakers with Bluetooth wireless technology let you listen to the digital music stored on your compatible mobile device in high-quality, stereo sound. And there's no need to worry about missing calls when the music's playing: the speakers act as a handsfree speakerphone and can be used to manage your calls. The speakers can be powered with the supplied Nokia charger or batteries, giving you up to 30 hours of music play time when using batteries. There's never been a better way to set your music free''
etc. etc. etc.......
I think these are still quite expensive but they are apparently exceptional quality.
