Judging by the lack of response, obviously nobody likes to admit that the buffetting of the ears does get a little uncomfortable on longer runs
I've never had buffeting on the ears; however, I will admit to brain-frazzle due to wind buffeted hair!
I know exactly what you mean ! Great description - I have brain-frazzle on most journeys, but tend to use earplugs all the time to drown out wind-noise/tyre-noise and my very loud exhaust. In the winter, I drive with Elmer Fudd hunting cap with woolly ear-muffs and so am nice and cosy and don't care what an idiot I look like.
In the summer (ha !) I just have ear-plugs and shamefully admit to quite liking brain-frazzle ! However I suspect if SWMBO knew of this windtrimmer she'd force me to buy one and I object enough as it is to fitting the side-screens when she's in the car - I much prefer the full-on open sided experience even if it does get a little breezy ...
But it's good to know that it actually works - I can't say that the wind-deflectors fitted to the side of my windscreen do very much though ...
