I want to attach the microphones to the outside of a pair of wireless
headphones, one mic on each ear, giving a stereo effect. Whatever the
mics pick up would be sent off to a wireless headphone transmitter and
then back to the headphones. So the person wearing this contraption
would hear what's going on around them, but only via the headphones.
I realize there will be some sound leaking in from outside, but that's
something I'll have to live with.. at least until someone decides to
give me huge amounts of money for wireless, soundproofed headphones.

Try one of these:

http://www.core-sound.com/

Nice shiny toys at both sites. I've used Core, and got great service
from them. I've never used Giant Squid.
