Just as an update after my previous post. I have now been flying back on the Super puma for a year, I use the afore mentioned earplugs AND my BOSE and am happy. I get low freq noise cancelling and the BOSE clears up the radios and intercom whilst the earplugs get rid of the high frequency damaging noise. I know some people hate the earplugs, and it took a while for me to get used to them, but give them time its worth it.
One note of warning:
WEAR YOUR HEADSET WHEN YOU GET THE PLUGS MOULDED INTO YOUR EAR
When you wear your headset it compresses your ear and puts pressure on the ear/plugs causing discomfort. Whereas if you wear the headset whilst moulding it wont.
Good luck

P.S. a friend did manage to wire in the CEP to his BOSE, but found the volume control a bit difficult, had to add a volume control into the loop too.
