Summary: Soundwise, these speakers are a great replacement for built-in laptop speakers. The sound is very good for speakers this size, they don't take up a lot of space, and they have the most important controls handy on top of the righthand speaker. However, they are let down by Windows (at least Vista & 7, I don't know about XP), which has trouble recognising them.
Summary: Great value for money, and for the price I would say they are great sounding, loud, and have an excellent build quality. To be honest I like the sound of all creative stuff.. Now for the negative bits - a little bit difficult to install if you are using windows 7. I gave up with the installation CD, and went to the creative website to download the beta windows 7 driver from there.. took some time, but all working well now.. Overall great value for money.
Summary: Good sound quality, easy to install - if you've got a Mac, any gadget installation is a complete dawdle, don't know about Windows. My only reservation is that its volume control is a bit 'digital' using the sound controls on the F keys: it's a not quiet enough and then one more nudge and it's silent so you end up using the volume control on whichever media application you're using which is not a problem if you're iTunes savvy and know all the key moves.
Summary: Great sound but don't expect them to blow your head off impossible with usb powered speakers software is bit fiddly to install but well worth it the best speakers i have owned would not think twice about recommend them to anyone
