I second what Linda says about the Clarity Aloft. I tested DC and Lightspeed Active noise models and found the Clarity to be just as good, noise-wise, but blocks a different frequency than the active noise cancellation headsets. Perfect for an Ercoupe. And since we sit in a "Goldfish Bowl" canopy, you can't beat the ability to wear a hat (No headband over the top). Had them for several years, and they're still the best! Clarity Aloft will be at OSH, I'm betting... (always are) and usually have the doctor who designed the system there, who can advise you on things like the size foamys for your particular ear canal, and best angle to insert. Usually, there's some show special.
PS. I find that I can hang my headset under the dash when I get out by slipping the mic boom over the metal fuel line that goes across at the bottom of the panel. Doesn't get in the way of entry/exit, and is really handy. I don't have radios under my panel. -Ron Black N93394 #717
