The voice diaphragm was already in previous gen which was available since 2020 when i bought mine ,most full face mask didnt have a voice diaphragm.Covid and quarantine made the voice a must.The screen protector too was in the boxes since years.
It would be nice if someone would demo strate how to setup the fit test adaptor assembly which on this POS requires removing that speech diaphragm.. the number of clients I steer away from this purchase because of how little resources are available is staggering
