A great set of speakers. And they are seriously loud, I very rarely turn it up past the quarter mark for fear of annoying my housemates and my neighbours. It's worth doing every now and then on some of the more punchy songs though, because it would be a waste not to!

sounds as good as my 9 piece stereo system, but it has a main plug that breaks very easyly, you have time to break it before the 14 day period of grace, & to break it you just have to plug it twice.

Great Sound Quality

Flaw in plug design

I bought these speakers 18 months ago for my computer and the sound is magnificent but after 5 months the on/off switch was making some funny noises and eventually a humming noise started. I got it swapped over through the store but now 18 months later my second set is now doing the same thing.

Logitech's Z623 speaker set has been designed with the film fan in mind. They are one of very few 2.1 speaker sets to be fully certified by cinema audio specialists THX, which should mean movie soundtracks sound exactly how the director intended.

I am sending the speakers back I played them with my ipod the bass was perfect but the small speakers kept popping even on half volume. I had issues like this before with Logitech too bad as I said the bass was awesome.

Accessory maker Logitech's been in the speaker game for a long while, but do its credentials show through in our sound comparison? We've put its Z623 to the test in our round-up. It's THX certified and has 200W of power output, but can it take the crown? Press play, and find out!

Well-designed and incredibly loud, but audio just doesn't sound as good as we'd expect from an expensive 2.1 set.

Logitech astounds us on a regular basis with their ability to produce dirt-cheap yet solid-sounding speakers. We can only imagine how thin their profit margins must be; heck, that's probably why there are so few other players in this segment.

Inexpensive, good performance with games and movies; lots of inputs; discrete bass control

Poor musical performance; with an overdriven midrange
