I knew a guy that flew with the QC2 headset with the U Fly Mike.
I have a Bose Aviation X headset. We swapped one day for a few minutes to see what the difference was.
The Aviation X has a little more ear seal coverage and is just a tiny, tiny bit quieter.
The Aviation X is also considerably more expensive. I got mine gently used on Ebay. Combined with rechargeable batteries, it was pretty economical.
I say, check out the U-Fly-Mike setup for TSO requirement suitability. If it won't cut it, check out some of the newer Active Noise Canceling headsets on the market. Some of them are very competitively priced, and just as good as the Aviation X.
Sidenote: Do not compromise your hubby's hearing protection. Over time, turbine engine noise, cockpit "wind noise" and gearbox noise produces hearing loss in the mid-vocal range. In other words, the human female voice. As he ages.. it's not that he's ignoring you, he just can't hear you.. or understand you.
I imagine this one's been milked to death, but if you help him stay ahead of it he can never use this excuse on you. Us pilots are slippery devils.
