These really are excellent value for money - and if all you really want to do is play games, in 5.1, watch the odd DVD and hear Windows warbles - then for this price you really cannot go wrong - and you do NOT need to read the rest of this review.
However - for music they are not so hot.
They do go loud without much distortion and the bass (from the subwoofer), is more than adequate - but they are lacking in the mid range.
The sound, when playing music soon becomes harsh to listen to and Vocals/Guitars/Strings lack presence.
All the satellite speakers (including the centre speaker), only have 2 small tweeters - really the left, right and centre speakers could do with having 1 tweeter (2") plus 1 squawker (3 to 4") to achieve a balanced sound.
Having said the above, it must be noted that I am a Music Teacher - so maybe I'm a bit hypercritical - but my previous speakers (Philips USB 350) were much better balanced, albeit somewhat unreliable and in the end died.
Note that you have to switch on 'Matrix' mode to listen to music - or it will just come through the front speakers only.
Also, if you use MSN Messenger it will not work in 5.1 mode, necessitating going into 'Control Panel' to switch to Stereo mode (a fault of Messenger's - not the speakers - but annoying none the less).
Yes, the cables are too short - but easily extended.
"Good - but not that good",
(but - probably the best you'll get at this price).
Great value for money,
Very little distortion,
5.1 really adds to your gaming experience.
Not ideal for music,
Problematic with MSN Messenger (damn Microsoft).
