The black one is a TRS (or stereo) plug and goes to the headphones. It must be plugged onto an appropriate jack that supplies audio to both sides. On a normal desktop computer, that would typically be a green jack and should provide audio to both ears. Newer laptops and smartphones use a TRRS jack which *may* be incompatible with the Yamaha headset. Some of those devices may have "smart jacks" which will detect the type of plug connected and route audio accordingly. A better test might be to dig up an old Walkman, portable radio, or maybe your TV set with a stereo headphone jack. The gray plug is for the microphone. This particular headset required "phantom power" on the microphone line to power the microphone. Some equipment may provide this natively, most will not. The headset should have come with a small box to hold a couple of AA batteries. If your device does not provide phantom power, then you should put batteries in the box, plug the headset into it, and plug it into your device. This will provide the necessary power to activate the microphone and provide audio to your device. The CM500 is a great headset and very popular with ham radio operators.
