i use the qc2 in a metro 3, works fine. definately not the bose x, but for the money, comfort, and music quality its worth it for me. after 10+ hours of flight time in a day, the comfort is unmatched. also enjoy using it without the adapter when not in the cockpit. would not be adequate for metro 2!! would be good for be20, havent flown other be turboprop products. good luck, two thumbs up here.
