Russ,

and have narrowed my choices
to the Bose X or the David Clark X11. Any comments, positive or negative,
about either of these two headsets?


I don't think the DC comes anywhere near the Bose - both in design and ANR.
OTOH, Bose does not offer music input.

Also, right now, I'd definitely wait until September to also try the new
Lightspeed Zulu, which clearly aims to be a "Bose killer".
