Am using a Sennheiser Headset at the moment that has ANR with no Batts. It does have the loopy euro connection but can get the converter pins. The ANR is better than the DC and not as good as the Bose. Nothing worse than the batts flattening and getting the echo. Had a Gallet helmet once that had the best ANR, was an aftermarket fit to DC cups, don't know the brand but the quietest ride in the shorts skyvan ever.
