Well, I just had my first flight with the Quiet Technologies Halo, and I have to say they live up to the claim that they are "As quiet as ANR." I'm used to wearing earplugs and "doubling up" on ear pro and having flown with CEPs a bunch at work, this headset was a breeze...and it felt like one too. No annoying clamping pressing my sunglasses' temples into my head. Crisp, clear comms...very refreshing coming from my DCs (even with the Oregon Aero Hush Kit installed).
I've seen some posts questioning their utility in a GA piston, but at first blush, these seem to fit the bill. I'm still within my 30 day return window, so I'd love to hear what the masses have to say...especially if you have any hard science against them, please send it my way.
I'll be bringing them to Truckee this weekend if anyone wants to check them out.
Oh, and I have thick skin, so bring it on
