Almost exclusively on anc except when out in wind where I turn all off and go with passive
My acid test has been 2 rides on the London Underground in rush hour and through Waterloo main line station on to the train towards Porthsmouth with no drop outs at all
That sucks, the electronic store completely paralyzed my unit, and it gets drop outs in sound mode at home. If I could get rid of the drops in sound mode everything would be perfect. I'll try giving it a factory reset...
