January 7th, 2008 - Tannoy demonstrated their PSP Speaker System at the CES. The system works by simply plugging the PSP into the speaker itself, and then the user plugs the other end into the video out. The speaker will recharge the PSP that's plugged in.
The speaker puts out surround sound at 50 watts. It comes with an infrared remote. Another added bonus is that the user can attach an MP3 player. It does not work with video files, though.
The Tannoy PSP Speaker System should be out by February, and will retail for about $199.99.
