The Package
Sennheiser didn't change the packaging they used on their older headsets simply because there was no need to do so. The GSP 600 comes in a sturdy and visually appealing box that depicts the headset from all sides, shows it in an exploded view, and informs us of its key features.
Inside the box, you'll find the headset itself, a quick setup manual, safety manual, and pair of detachable cables. The longer one (2.5 meters) is used to connect the headset to a device with two separate audio ports (i.e. your PC), while the shorter (1.5 meters) is equipped with a 4-pole TRRS plug, which should be used for consoles and mobile devices, including most laptops.
