"Launched in early August, the Cougar Immersa Pro gaming headset is an update from the original Immersa release. While it uses the same dual headband support and soft leatherette covered ear cups, the Immersa Pro now has the sound level control and mute switch on the right and left earcups, respectively. This means you no longer need to use the in-line controller on the USB cable to adjust either of these settings."
