The only drawback:
The audio signal is transmitted via a normal (supplied) mini-jack cable from the sound card. For this purpose it is externally plugged into the sound card and passed through a PCI slot bracket with a recess internal to the pit. The isolation of the enclosed cable not apparently aussreichend strong to completely shield arithmetic operations of my computer. Therefore, you can hear a faint noise when the PC is working and the speakers have nothing to do.
