I got a new Bose for Christmas. They now use two AA's and have an auto
shutoff feature. You can send your headset to Bose and have them put
that on yours if you want.

I sometimes fly an Aztec with a Bose headset. It makes a world of

The only fault I find with the Bose is the need to keep an extra 9 volt
battery handy. If you leave them on, the battery will run down. Not a
big deal to change out during flight. You can still hear ATC but you
will be getting the noise which would be normally filtered.
