This product is great i love the 3-D sound button which gives the music a crisp feel and loud surround sound feeling like in a cinema.
Just perfect for any small-medium dance or sin-a-long because it has such great sound boost that you can see the cones throb and feel a small pulse from the sub woofer.
The Remote is awesome to that has rewind, fast forward, play/pause, and volume up and down. Great for watching your movies or listening to songs without having to get up and fiddle around with the console.
But you need a mains plug and the Sony PSP charger to use the speakers because they (but they do charge your PSP with mains plug, plugged in.) don't come with a built in battery so I suggest getting a PSP portable charger so you can listen to your music or watch your movies on the go or where there's no mains plug, because the speakers are quite bulky, So you might need a bag of some type.
