I've had one of these for years, and really like the noise reduction.
They're long since discontinued, and Heil has no information on them and
does not repair them.  Mine was always susceptible to RF, and eventually
broken wires in the cords made them unusable.  So, I spent a ridiculous
amount of time reverse-engineering them and finding a fix for the RF
problem.  Let me know if you're interested.
