There is a simple solution to the quick disconnect problem for those
using military style helmets ... count me in as one of those!

I've been using a Flight Suits HGU-55 helment for a little over a year. 
It's expensive (>$600 in Kevlar), light weight (~DC headset), and
overall not too bad to wear (anything is hot in Arizona in the
summer!).  One thing I found by accident was to get the single plug
U-174 mic/phone connector on the helment and use a flexible U-174 to
Type 88 (two plug) adapter (plugs connected by about 3" of wire).  The
adapter makes a very nice emergency quick disconnect since it easily
moves in the direction of the helment cord.  A standard Type 88 would be
at right angles to the direction you would tend to pull it (at least in
the Pitts S-2B I fly).  I, of course, have tested it more than once in
getting out of the airplane too quickly on a hot day!

A cheap solution and one less thing to worry about in an emergency
egress!
