Using the old headphones we wore them in front on our ears, on the temples.
Didn't wear out the ears, physically or aurally.

| Sure, reducing gain does the trick but it defeats the whole purpose of agc

to

MFJ

| response. The agc still wimps out but I don't notice it with those
| speakers. Headphones are a different matter. I simply don't recommend them
