I bought one of these recently.

During use on an aircraft there is sidetone--hearing yourself in your ear when you speak.
I get perfect sidetone when: a)speaking to the other person in the cockpit, b)using the PA, c)speaking to the pushback crew below.
However, when doing the most common thing, talking on the radio, the sidetone is immensely muted and of low volume.
I called DC to ask them, and the gentleman on the phone instantly said it was the aircraft. However, after speaking with a friend who has the exact headset I learned his produces perfect sidetone in every condition.
So the question is: What kind of things happen during sidetone generation that would be different between transmitting on a VHF radio versus an inter-cockpit intercom? Could it have anything to do with the wattage of the radio?
I'm out of my element on this; any insight would be appreciated.
