A good kit 5.1 but lacks a little depth.

The pros:
A 5.1 kit black high tech look very pretty
Remote control
Adjusting the volume of each speaker, allowing to amplify the low (but limited to a scale of 10)
An AUX cable to connect the speakers directly to your computer or MP3 player jack (3.5).
Long cable for surround (rear) speakers to place them where you want!
Cables to connect directly to a DVD player.
LED display to set different volumes of the speakers, etc ...

The -:
Originally, the sound is generally very acute but (as mentioned above) the setting of each speaker overcomes this concern, enhancing the subwoofer.
Subwoofer limited to a scale of -10 to +10 which does not boost the bass enough.
Manual in English and German, not French.
2xAAA batteries for the remote control, not included in the pack ... it's a detail, but it's a shame to have to buy after receiving pregnant ... especially as this remote control helps set the speakers!
Unable to connect it to an HD game console (PS3, PS4, 360, ...) except through a DVD player to amplify the signal (but I have not tested this)

IN SHORT:
This 5.1 kit is a very good price / quality ratio! In addition to its high-tech look really pretty. Also the LED screen adjusts the volumes of the speakers, which is very convenient!
His only big flaw (in my opinion) is that you can not connect it to an HDMI video element such as a game console, etc ... Note that alternatives do exist.
