Hi Bryon
The FO voice normally (and logically) comes from the right. When wearing a good quality set of over ear headset to excludes the possibility of also listening to the other person one must obey (the wife). I mean having one earpiece off the ear to listen to the 'outside' world. If I have the right earpiece off my ear I can't hear the FO and when I have the left earpiece off I can't use the microphone.
Would it be possible to have the option to have the FO in the left ear so allowing the headset to be reversed? Another option would be to allow all FS2Crew sound to be switched to mono. There are no Windows controls to do this.
I said normally the FO comes from the right. The exception is the Airbus Flight Control Check responses which are mono.
