| Tatsuro,
I have a Telex headset, originally designed for aviation.  It did a great
job of blocking out the noise during a couple of  Multi/Multi operations I
participated in.  The secret, I think, is that the headphones are well
padded and fit tightly around my ears.  I have also used the Heil Proset
and I think my Telex set blocks out the noise much better.

I agree with Dan.  I put an HC-4 element in my Telex headset and it
produced a big improvement on my transmit audio.
Good Luck!
