[Elecraft] Heil Proset Headphones

[Don Wilhelm]

Irwin,

The main difference is in the microphone element.
The PS-6 has the Heil HC-6 element which is a wide range dynamic element 
which has a relatively low output.
The ProSet-K2/K3 uses an electret element which has a high output level 
- it needs to have bias turned on.

The K3/K3S is quite capable of handling either of them.
