I 've had nothing but good results with mine. It is well built. That aside, someone stomped on mine and an earbud broke, but LS was very quick about fixing it. I basically got a brand new headset back. The housing is magnesium, not plastic. The mic works great if you wear it right. I flew with a Bose X for years in turboprops and corporate jets, Nice, but overkill for a Falcon 2000. And for the price of the Bose X, I could buy two LSM1. Apples & oranges really, since the LSM1 is not ANR. For me, I like the LS Mach 1 and recommend it, YMMV.
