I Got One
I took the plunge and bought one of the few DC Pro-X ANR headsets available at OSH last week. I was concerned about the ability of the muffs that fit on the ear rather than completely over the ears to seal out the noise in an RV. DC is offering a 30 day return policy, so I went ahead. I used it on my 2.5 hour flight home after OSH in my RV-9A.
At first, I was somewhat disappointed at the amount of noise that leaked through. However, after multiple attempts to adjust the headband length and the exact position, I was able to find the sweet spot and got extremely good sealing, resulting in much lower noise than my old cheapie ANR headset. The DC's are so light you don't feel the weight, and the ANR capability is very good. Everything goes silent when the switch is turned on. I am very pleased. I know I will have to go to some trouble to move them around to find the right spot, but it will be worth it. No clamping force on the head, and no leakage around glasses earpieces.
Now I will have to save up to buy a pair for the wife!
