I found a F 16 helmet,custom silicon In EAR Plugs with CEP speakers ( or foam earplugs ) and an option for a microphone mask the best way to communicate,as well as being a head protection .The helmet alone still gave resonance from the airflow around my head ( propeller generated )
I use a Becker radio,AR 6201
Possibly this is of use to friends in the Bucker and open cockpit community.
