The sound is distortion free, and so is the bass. I have bought two from mightyape.They are so good that I damaged my MacBook Pro because of it's bass vibrating my mechanical disk.

I bought them from mightyape and they are a set of good looking and powerful speakers. Perfect if you like playing games and watching movies on PC.

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

In the age of the ubiquitous iPod speaker dock, it seems few manufacturers are still making quality speaker systems designed for computers. So it's refreshing (and a little surprising) to see one of the leaders of the pack, Logitech, step up with one of the best-sounding 2.1-channel PC speaker sets...

Reasonably priced; Excellent audio performance; Extremely powerful output; Subwoofer level is easily adjustable; THX certification

Good sound at a good price

Deep; rumbling bass; Attractive design; Works with multiple input devices

Compact Design; Easy To Use; Great Sound Quality

None

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 recently purchased these speakers [...] and I couldn't be more happy! The sound quality is excellent, and the electricity capabilitis of 400 watts is amazing. [...] For consuming 400 watts of electricity, you're getting an awesome deal!

Ultra-thin TVs with invisible speakers don't sound very good, but Logitech has just the solution with its affordable Z623 THX Certified desktop 2.1-channel audio system.

The Logitech Z623 offers powerful stereo sound at a price that can get as low as £110 in certain online outlets, which is attractive. The system sounds bold and offers powerful deep bass that makes it easily a good option for partying or waking up the neighbors.
