nal you are listening to. It's very tiring to listen to.
I'm right now at the point of testing with an audio analyzing software tool
and will report.
The question now is, what can we do about it?

Are we (dutch) all using the same version of Heil headset?
I never noticed this high hiss with my old Telex headphones (with a smaller
freq-response I guess)

Great news about the K144XV!
I just wonder if the K144XV has the possibility to "separate" the RX input
and TX output and become available at the back panel?

the preamp is installed as well.)
