Logic 3 PSP535

Any Sony PlayStation Portable owner will no doubt want to take advantage of its movie and music playing ability. However, the built-in speakers are not that powerful and will not do films or audio justice.

Logic 3's answer is the PSP535. Just slot a PSP into the dock and audio will be amplified. Sound quality is reasonably clear and a flip-down sub-woofer on the back gives audio a kick.

The extra width provided by the PSP535 makes watching movies easier on the eye. There is a button to activate a pseudo surround-sound option, which works quite well, and a line-in port on the back for attaching external audio devices such as portable music players.

What's more, the PSP can recharge through the PSP535. It will also run on 4xAA batteries which provide six hours of power.

If you do a lot of travelling and have movies and music on your PSP, an extra £50 for this device is well worth it.
