Well, I've tested and tested the unit. Here's the lowdown.
The headset does reduce windnoise, but does NOT eliminate it.
VOX plain and simple sucks. The headset responds better to using the PTT as all units do. If you can stand repeating yourself, or just yelling HEY before you start talking, then there is no problems.
Other than that, a worthy investment @ $45 shipped.
The company is Clearer Com
I got my unit in exactly 7 days from ordering.
NOW, with that said, I have seen similar units on e-bay for $29+ shipping, but I do not know if these are the same units.
Also, clearercom.com has a new dual transducer unit in the works....although about 3x the price as the standard unit.
Hope you enjoyed my writeup, feel free to ask any questions.
