I purchased two sets one for me and one for the wife.
Two things that I had to deal with:
First not all intercoms are compatible so make SURE that what ever you use is.
Second don’t put them on backwards. Yes this sounds silly but I had an annoying POP intermently in both of my headsets (the serial #'s are 1 digit apart) and I even had the Bose reps at Sun and Fun examine my head sets. The cause could not be determined. Finally in desperation I called the factory and got a tech on the phone who pulled up my records. He asked if I could have had them on backward (Left ear cup on the right ear and visa versa). Naturally I could not have been that stupid.
WRONG
The headsets are so comfortable by comparison that the wife and I had on occasion swapped sets without realizing it and the mike will swing into the appropriate position. Bose allows the cords to be mounted to either earcup and you should take advantage of that. In my case the intercom is center stack mounted and NOW both headsets cords are in the center of the plane when worn rather than running across my chest, which I never noticed.
The Bose people offered to swap the cords which I declined (I can use a screwdriver) but they did send at no charge 2 sets of new leather earcups and the associated stuff. I was told that the earcups have a slight angle to them and MUST be worn over the correct ear and if not the leather earcups will take a set. The ear cup seal to the head is critical to the ANR operation.
I can not say enough about the people at Bose they were great. Now I just need to learn my left from my right.
PS: Incase you can not tell I think the head sets are the best I have used. When not worn backwards.
