Logitech Z120

I bought it for the office and they are perfectly adequate.
My application field is limited to web radio or background music.
Of course there is no bass coming out, but there are also no bookshelf speakers.
What I have to complain about is the cable length.
The connection between the speakers is about 70 cm, which is just enough for a 24 inch screen.
The connecting cables are about 120 cm, and that is too short in my case and I had to extend.
It takes 3.5 mm jack for audio and USB as a power supply.
