My wife bought me the new A20 headsets a couple of months ago (which I LOVE). Figuring she'll do more flying with me, albeit not as frequently as I planned to, I figured I'd get something a little better to protect her hearing so I purchased a used Bose X headset. Works nice and she was okay with it until she tried out my A20 and now of course she wants to fly with my nice headsets. I'm considering just upgrading hers to the A20 as well so we are both happy Anybody know if Bose offers a trade up program?
