Unless this is a model that is currently unlisted on monoprice, I believe that there is a fallacy in the description that there are headphone and microphone ports, the model on monoprice that matches this only has USB.
The model that does have microphone and headphone ports is also a full size keyboard with numpad, and is also more expensive.
