DC Pro X
I have been using the Pro X for a few months now flying a single engine turbine.
The only thing i notice is if the air vents are directed at your head, you will hear the wind whistling through the seals of the headset. In our environment this can be a pain with mid 30 to 40 degree days and wanting the AC on most of the time.
This is due to the smaller ear cushions.. They are comfortable. The noise cancelling works well. I haven't had a chance to try the bluetooth yet.
For the price you wont regret the purchase
