Does your oxygen mask have a CX-4707 cord that spirals down the oxygen mask? Then you will need the CX-4708 AIC cord in your helmet.
The CX-4708 AIC cord connects the two earphones together, exits your helmet, and stops with a two hole U-172 plug. A CX-4708 Cord in your helmet accepts either the CX-4707 oxygen mask cord or a FSL cord.
If you need to use your helmet without the oxygen mask you will need a FSL cord that plugs into the CX-4708 helmet cord.
