HP ProBook 450 G6 Notebook PC

The 3.5mm "combo audio port" on the right side of the HP ProBook 450 G6 is used for headphones as well as powered speakers and headset microphone. My question: Is this 3.5mm combo audio port a TRS or TRRS configuration? This difference is very important since they are not interchangeable and audio devices come with either one configuration or the other.
