Listening to the radio can sometimes be difficult as a result of external noise or attempting to hear very weak signals. I have two different headsets for this purpose. Firstly, I have a Heil Proset.
I find that using the Heil Proset can considerably increase the intelligibility of received signals. Furthermore, because it’s lightweight, it’s comfortable to wear for long periods of time.
Heil design and build their own microphone inserts which are tailored for radio communications use.
