Been flying with the Zulu Lightspeed for about a year; well worth the coin, but you should be concerned about leaving it on the plane. One guy I know who had a Bose left it on and by the time he got bact to the plane from ops it was gone. Most crew members ca figure out the mic forward function pretty quickly (although not all). What I don't understand is why all our planes don't just have them permanently installed, because the increase in situational awareness while wearing mine and the fatigue reducing effect is noticeable. Good luck with your decision.
