WNR
I`ve tried a few ANR headsets recently. I`ve found the best to be "Pilot" ANR headsets the batteries are self contained in the sets and only need to be recharged after about 30 hours(according to the manufacturer)
The lead is detachable so its quite easy to get the appropriate helicopter leads. You will probably need two leads (one UK Nato & one US Nato) for the R22 & 206.
Also make sure you get the metal band accessory that aerobatic pilots use, it gives a lot tighter fit.
Shop around for the best price.
