Really appreciate the replies.

I own the Bose A20. Great headset, and has become headset of choice for many of the 747 crews, but the 787 is much quieter.

Sandpaper - have to wear something. Company provides a mini-tel, and we bring our own earpiece, so I would be with the "community" microphone! No thanks.

Clarity aloft. Telex 750. Telex 850. Three choices so far. Keep them coming please.
