You may have already done this, but what you need to do is test your headset
without any other headsets plugged in.

Try the same thing with your other headset.

If both headsets work OK when they are plugged in separately, your problem
may be an impedance mismatch.

Try to borrow another headset exactly like your primary headset, and plug
both of them in at the same time. If that works OK, it probably is an
impedance mismatch problem.

If you do find an impedance mismatch, the simplest solution is to just make
sure all of your headsets are identical. Or, you can check the manufacturers
spec sheets and make sure whatever you buy is close in impedance to what you
have.

The audio from the overhead speakers are fine, but the audio from the
headset is very weak. I have to turn the volume to max, but then I get
a lot of distortion and can hardly understand the transmission. The
results are the same from both radios. The problem is not with the
headset, because the results are the same on two different headsets.
The outgoing transmissions seem to be fine also.

Before I take the airplane to an avionics shop, I wanted to ask the
group if I am overlooking something obvious.
