They are way cool. LS had them on the booth for testing.

Dang. I can't believe I missed them -- but we've been so happy with
our 3Gs that I never even looked at headsets this year. (I didn't
even do my usual "Walk-into-Bose-tent-let-them-schmooze-me-try-them-on-
marvel-at-the-price-and-leave" routine this year...)

WRT to the new Zulu model, I just hope Lightspeed learned from their
quality control issues. They learned a hard lesson with their early
models, and pilots aren't going to have any patience with an $850
headset if it isn't durable.
