When a player activates their Muffs using the Muffs button, their headphones light up to show the amount of cymatic power boost remaining and the Muffs music plays. Active Muffs give you faster movement, stronger melee attacks, and fully automatic firearms.
Muffs run on charges. Collect charges by finding batteries from around the maps. Players have a storage capacity of 3 charges that are denoted by the three slots shown on the left side of the Muffs. Filled charge slots are green while empty slots appear gray.
