Q: i have a BOSE A20 ®ANR HEADSET - DUAL GA PLUGS - WITH BLUETOOTH. may i know if i can buy this and change to helicopter plug? how troublesome it is to change? and will it damage my headset? thank you

Yes, this will convert your Dual GA headset into a U-174 helicopter headset. It is a very simple install. Small set screws need to be removed, then the cable assemblies are changed out and the screws put back in.

Q: Can you confirm the coiled section is between the volume/battery module and the microphone? I have an older version which is opposite, coiled between the plug and module and straight between module and mic.

The coiled cord is between the volume/battery module and the Mic.

Q: Is this a low or high impedance mic?

This cable assembly is a high impedance mic (civilian).
