I just got my hand on two (used) David Clark headsets. So now starts the headache of interfacing them.

They come with two large plugs (in different sizes). And even if I fitted the plugs the microphone must be amplified.

There is a converter box out there and I might just get two of them.

Right now I am using (too) cheap headsets when flying online on VATSIM. I hope these also can add better sound quality. But most important they are just awesome!
