I bought to replace the one I had at least 15 years that worked perfectly, but which were much too large. After a few months, they burnt my sound card to my motherboard: motherboard change. It burnt me the USB port of my Free Box. All this before me to realize that it came from these speakers! I should have been alerted because they were subject to interference (Free Box, monitor): buzzing, crackling. I bought a pair of Logitech speakers. Since then, no more worries.
