I use a DC with post fitted ANR, and installed in a cloth cap to hold it secure. The mike is a standard H10-13.4 type. I have an extra sock on it over the top of the standard one. The extra sock is from a Lynx headset so it's quite a big one. I cut it down the inside to make it fit and it's held in place with a black hair elastic band.
This works really well for me.
The Lynx system is very good, being designed for the Microlight environment. However the connectors are all bespoke so you have to invest in the whole system which limits its value, particularly if you're flying different types.
