Handsets & Mikes

Hint:  It's very important that you check which handset you use.  Some of these will NOT work with military radios as a handset!!! (guess how I know this).

Trivia Question: The only mystery in life is why the kamikaze pilots wore helmets.
Possible answer

This will NOT work with mil radios with a single connector,
BUT may work if both are used like on a PRC-25/77

Possible answer to why the kamikaze pilots wore helmets.

American pilots wore a very similar thing for the same reason (I had one when in grade school): to hold their earphones and block noise.
Conventional headphones use straps over the top of the head and depend on gravity.  That does not work in a airplane.  The HS-30 is a W.W.II vintage headset that might or might not stay put during aircraft manoeuvres but does nothing to block noise.
Note it's very noisy in a W.W.II airplane and so headphones like the Trimm Featherweight would do nothing to block the sound.
Some modern headphone,s like the H-161 above, surround the ear and are designed to block outside noise as are the Clark brand aircraft headphones.
If you look closely at the W.W.II pilot "helmet" you will see it has a large noise blocking rubber part surrounding the hole for the actual Trimm type speaker element to block aircraft sound.
