We just got these packs and they're great. However the masks that came with them do not have voice amplifiers or the ability to attach voice amplifiers. Is there a solution to this? It's the same mask with the bone conduction radio communication function

I like how one firefighter has a melted helmet. OOPS...missed that!! Should have been out of service a long time ago. Seriously, a very good example of what not to do. Poor planning for an informational video.

That helmet at the very beginning of the video is disgusting….
