Working in conjunction with CorPro, KSE have developed and tested a PPE solution for use by helmet users. Using the Half Mask 1400 with a combination of adaptors the mask utilises a M7 Electret mic, or an updated adaptor that incorporates a dynamic mic, to provide both respiratory protection and communications. Tested both on the ground and in the air the Half Mask could be the solution you're looking for? Contact KSE on 01332 332442 for more info.
