[QUOTE=22clipper]Yeah I had to surrender my Gentex for a Bose when I got too deaf to hear ATC properly, but I miss my bone dome. I briefly considered removing the Bose earpeices to fit into the helmet but the Bose has complex ports on the outisde of the earpieces & I was concerned the relocation might compromise the ANR.
I have a Gentex also and retrofitted it with an ANR kit with no problems. Now I have all the benifits of ANR with my bone dome.
I cannot remember the supplier, but they are at Maroochydore airport and advertise in the Aviation Trader (in Australia). It was significantly cheaper than the original models. I think about AU$300.00 approx.
