Previous Customer Questions For Sennheiser HMEC-25-KAP ANR Headset: Ask Your Own Question

On Saturday, February 07, 2009 a customer asked: Q: Can HMEC-25-KAP be used in the cockpit of 747-400? A: Unless the 747 that you fly is specifically wired to power an ANR headset through the microphone tip (not usually), this is not the right headset for you.  You would want the HMEC-25-KA or HMEC-25-KAS instead.
