[TenTec] Corsair comments

[Michael O. Hyder]

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
| and it's those strong signals that sneak up on you that really do a number
| on your ears.
| I've tried all manners of audio limiters. They do work but they all seem
to
| induce some distortion which I find more anoying than the agc. I use my
MFJ
| ClearTone or Mil 166 speaker which have narrow response and poor bass
| 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
| if you value your hearing.
