It is a good idea to use a pigtail adapter if one is going from a small jack on a radio to a larger jack for legacy headphones that you prefer.
Simply create a plug, pigtail of suitable audio flexible cable, and a jack to accomplish the transition without an adapter putting heavy weight onto the radio jack. Allow enough length for the adapter to be supported on the operating table surface. In line jacks might be hard to come by. However, a suitable protective boot can be fashioned over a conventional large jack with shrink tubing. Use as many sizes as you need to adapt from the back of the jack down to a smaller size for strain relief contact with the cable, telescoping one piece into another. Such adapters have allowed me to use 1950's high sensitivity military headphones on the most modern radios, with good results. I have done microphone adapters the same way, to switch from one brand of radio to another without changing the mike plug. A quarter inch jack will fit the body of some electronic push button switches that have a rectangular box structure that fits behind a rack panel. Just unscrew the switch guts, and use the box for the jack. The shrink tubing trick closes the back of the box as well.
