The ELAD uses the same Mic Wiring as ICOM, so any mic/headset with the pinout for ICOM will work.
Check out the RS55SL SuperLight Travel Headset from Arlan Communications (RadioSport) http://www.arlancommunications.com/products/amateurRadio/radioSport/rs101555SL.asp
It also has a jumper that has a right-angle plug for the headphones to keep the cable out of the way of front panel controls. It also adds an inline PTT button.
