"The Cougar Phontum gaming headset incorporates a 53mm driver to provide more audio output across multiple situations than the standard 50mm driver. Next, Cougar utilizes a dual-chamber design to achieve a profound distinction between bass, midrange and treble frequencies. Finally we have a graphene diaphragm to reduce distortion due with their lighter and stiffer construction – making for faster response with less unwanted flex of the cone."
