Ok. I figured if the USAF zigs, the USN will zag. Because reasons.Also if you search "Bose A20 headset" you get some interesting results - including qualification test reports for a number of airframes. Including P-8 mission workload studies with the A20.
@sevenhelmet I don't believe passive aviation headsets are being used anywhere in the .mil world. Maybe Army.
We also used DC headsets when I was a TPS student in 2014- the only time I flew with a headset on active duty. It’s very possible they’ve been replaced. @IKE ?
