Wehrmacht Doppelfernhörer (Dfh.)

The Wehrmacht Doppelfernhörer (Dfh.) is a standard WWII German military headset. It features 4000-ohm high-impedance Bakelite earcups and a steel headband. Models like the Dfh. a and Dfh. f were used with field radios such as the Torn. E. b. 

The manufacturer code "jmd" on German Wehrmacht equipment stands for Telefunken (Gesellschaft für drahtlose Telegraphie m.b.H.), specifically produced at their factory in Łódź (then Litzmannstadt) in occupied Poland.

Unfortunately, it no longer has its connector.
