The installation is straightforward and aims to significantly improve comfort, especially when worn with eye protection, by preventing the earpads from squeezing the glasses into the head. The gel pads also feature a channel to accommodate eye pro and a relief cut for better fit, potentially increasing noise reduction by up to 10 decibels by maintaining a better seal.
