I read the whole thread and found nothing on the specific type. My company is thinking about buying DavidClark H10-66XL to use with our 109/206/212/412 fleet. Any thoughts about this headset compared to 56XL and 76 type. We are on DC from the start and switching to Bose isn't an option.
Is there any problems with 66XL headset if used on two bladed rotor like 206/212?
