Hi Rick,
Sorry it has taken so long to get back to you with the results of a flight with Clarity Aloft headsets(too windy to fly)
I flew this morning using them and I would rate them about the same as Zulu without the noise attenuation turned on, in other words very noisy. If you still want to get a pair I have two sets that I will sell at half new price, hardly used.
Regards Bruce
