Compact headphone microphone of excellent sound quality, ease of use, and sensitivity. Clip the microphone onto the headphone cable as close to the mouth as possible. Use the mini clips on the microphone cable to latch the microphone cable onto the headphone cable. Insert the microphone jack into the Mic Input of the soundcard/audio input device. Adjust the Mic Input Level in the soundcard’s software/audio input device.
This is a great alternative if you already have a nice pair of headphones instead of buying a headset for your PC.
