The reasoning behind this is due to the influx of VOIP (Voice Over IP) companies, like Vonage and Skype, who have developed headsets that use a single jack instead of 2 jacks so that you can use a special headset to listen and speak. This adapter allows the use of an external microphone and headset or speakers with PCs and Laptops. The latest computer models from leading manufacturers are following suit with the iPhone and Skype trends by combining the traditionally separate headphone and microphone jacks into a single jack.
