I too like chicks smiling - better than spitfires - it just is not in the context of the song.
I guess 1 second of Peltor Optime III on your head would give you all the answers you need - it isolates much better than any closed headphone; add to that isolation of IEMs - and we are talking 50-80 dB attenuation, depending on frequency. This much isolation allows for monitoring at as close as possible to the real SPL level.
Otherwise, you have to turn the level in whatever headphones/IEMs used UP until sufficiently high
SIGNAL ( signal in headphones ) : NOISE ( actual sound of the performers )
is reached; the lower the attenuation of "noise", the higher you have to turn up the level in headphones/IEMs, leading to errors. Ear has sensitivity approx to the Fletcher-Munson curve http://en.wikipedia.org/wiki/Fletcher%E2%80%93Munson_curves
and if monitoring at any level sufficiently removed from the real one, it usually leads to coloured recording.
It directly affects the decision where/how to position the microphone(s).
Not to mention the danger of ear damage; renaissance choir *can* be monitored with say + 10-20 dB level without threatening hearing damage ( while producing coloured recording etc ) ; how about some heavy metal band - 130 dB plus in headphones ?
And Havi B3 ( with crosfeed and appropriate bass boost ) , even under mufflers, has the best minimundus soundstage I have heard yet. It is better than most full size cans in this regard.
