Ive looked at solving this hearing protection/comms issue myself and have seen these from another thread .. https://sena-industrial.eu/collections/communication-headsets-with-hearing-protection/products/tufftalk-lite?variant=37545784246441 These seem to be able to do the lot, including bluetooth and comms with another similar headset. Granted this is not a cheap solution, however seems that it will cover all angles if you are ok with wearing 'On ear' protection. An added benefit of the bluetooth design is that there is no wiring for the intercom and it will double up as a link to the phone or music at the same time.
