These audio cables connect soundcard audio ports (line-out & microphone) to front panel I/O header. You have to make sure that your PC case's front headphone interface supports speakers cut-off function. The cables exit through the PCI opening and plugged into the line-out and microphone ports on your soundcard, located at the back of the PC. You can use our CPX073 Metal Plate to hold the speaker socket. Your speakers are plugged into this socket. When headphone is plugged on the front panel, your speakers are automatically cut-off.
