I read the article and went to research further on reliability of lavalier mikes. According to a comment of a customer on B&H site (under one of the Sennheiser mike's in $599 category), all wireless mikes, even the most expensive one costing around $3,000 will have drop-outs of signal when used on the streets of busy cities like NYC and such. So then I thought to myself, what would be the most reliable approach to capture high quality audio when it comes to interviewing people on the streets? The idea popped quickly. Use a Samson Zoom H2 connected to Electrovoice unidirectional mike. Although H2 itself has multiple condenser mikes inside (even surround sound), none of them are unidirectional. So with this set up there's more work in post to sync the H2's audio with on-camera mike, but you get crystal-clear reliable audio without any RF interference or drop-outs. I haven't yet tested this work flow but I think this hits home.
