Thanks Andrzej - this looks very interesting and quite a bit cheaper than the Clarity that I'm also interested in.

This is what I use, http://www.quiettechnologies.com/ind...ormation_id=12
I use a headset because I self launch, but I never take it off. During silent flight I just remove one earbud to hear everything else. The sound is very, very good. I have been using mine for I think 7 years now without any issues.
