I wanted to get Logitech headset not long ago, but after reading on logitech forum problems about their products I decided to move to another very cheap but with good quality for my needs.
I was told that Genius 2.0 speakers are the best, easy to repair and about 20-50e. Using one for about 5 years, had to repair power supply and they are working same like in time when I got them.

My advise is if possible return speakers and use Genius 2.0
