Hi John,

I agree that headworn mics mean you can't turn your head while
recording, but the operative word here is QUICK, and it does give a
pocketable solution for those just-in-case scenarios.  I find
breathing through my mouth is quieter than nose breathing.  And if
you have a little time to spare you can always rig up the mics on
something other than your head.

Of course it is better to have a rig tripod-mounted and then stand
well back but you can't carry a tripod in your pocket :-)

cheers,

Vicki
