Philips Fidelio SoundSphere looks though as a space rocket both outside but inside too. It has 100W power and you can be sure you can use these power to the max-may want to alert your neighbors first. It runs on batteries so you must be sure you got this cover, also it needs a wireless network. You can stream tunes from your iPhone, iPod, iPad. The exterior design it probably one of the most attractive you can find. This device is not a cheap one, but you can be sure it will last a very long time
