Boomsets (headsets with boom microphones) should have been correctly certified for acceptable CVR noise level operation for specific aircraft models. That is not to say that other individual choices of boomset cannot be installed with the correct plugs and will not work to the pilot's satisfaction, but not every make or model will have been certified or would necessarily be acceptable to the airworthiness authority. The aircraft manufacturer's IPC should advise which boomset part numbers are already certified.
