It's the logical progression to both. Still the 1968 space age seat from Henry Massonet and still a sound system capable of hooking up to your iPod or iPhone. But the new 'Go' version also adds in a Lithium-ion battery, offering up to eight listening hours of 'omni directional sound' cable-free.
It can knock out a fair bit of sound too, packing in 2x 25w stereo sound, a 70w class D amplifier, 4 tweeters and a subwoofer. There's also a remote control and the option to charge your iPod and iPhone as you play. All of that contained a classic space age design.
You don't have to go for the red, four colour options are available, all priced the same – £346.
