Sennheiser HMEC 25-KA modification?
Hi. I use the above headset on an Airbus 320 and find the volume too loud with the radio vol at minimum. This headset is not fitted with its own volume control.
It should be a simple enough mod to fit a suitable potentiometer or even a fixed value resistor to the headset to rectify this. Can anyone suggest if;
a) this is the correct way to resolve the problem.
b) an appropriate value for that resistor.
Unless anyone has done this before I'll figure out the mod itself, it's the spec of the resistor that I need.
