The nomenclature of vintage aviation headphones by Peltor

[yahya]

I have a simple question. I am looking for the nomenclature of vintage aviation headphones made by Peltor in the 1980s, with white earmuffs and the PJ-055 connector only, which did not have any boom microphone with a separate PJ-068 plug. If memory serves, the piece resembled the Peltor 7000-series headsets, but without the microphone. Does anyone remember what was the type of that item? BTW I don't think that the headphones were made by Telex.
