Hi
I tried the Lightspeed Zulu in a King Air 100. It worked great. I normally fly with a Bose and the Zulu was just as quiet and comfortable as my Bose. The Music and Bluetooth is a real plus. I probably wouldn't use the BT but the music is nice. I tried turning off the ANR during the flight to see how quiet the headset is without ANR. In the Turboprop it's not that quiet (w/o the ANR) and I missed a radio call. In a real situation I would just pump up the volume of the radio so I don't miss any radio calls. But I wouldn't fly without it turned on anyways. I carry extra batteries in case they fail. I posted a review of the headset on youtube check it out
