[Elecraft] TRS connectors - Heil Foster adapter

[Michael Blake]

Don, it also seems obvious that the 1/8” TRS female, use by Heil on their adapter, with the ring shorted to the sleeve serves only one purpose.  That would be to prevent using less costly, higher quality gaming headsets with their adapters.

Yes, when used with Heil adapters, they will not work because the ring is shorted to the shell.  The Heil adapters are designed for mono plugs normally used on the Heil headsets.
