I'm pretty sure I can even hear windnoise when the ANR's are turned on, unless it's just my tinnitus that isn't being drowned out by the motor. Anyway, ANR headsets should be the first thing any young pilot buys. If their hearing hasn't already been permanently damaged by the amplified musak of the day, a cheap passive headset and a lycoming up front will do the job shortly after. Hearing is so easily damaged and doesn't tend to come back.
