I was doing pattern work recently with a crummy old headset with poor
seals. I was expecting just to be annoyed by the extra noise (and of
course, I was) but what really surprised me was how much information
was in the wind noise -- as I sped up, slowed down, applied flaps, etc.
I could really hear it even without looking at the airspeed indicator.
It made me feel more in-tune with the airplane, and I liked it a lot,
in the pattern. Probably a lot less attractive during cruise.

I can't think of a way to achieve this effect on purpose with a decent
headset. It seems like jamming somthing under the ear cup would be
uncomfortable and bad for the seals. Is there anybody else who likes to
listen to their airplane *sometimes*, without giving up the radio? How
do you do it? I'll be buying a new headset next week at Oshkosh.
