Title: poor reliability
Review: Poor reliability. The wires broke three times at the same spot - where it enters the plug. Each time I sent it back, customer support sent me a new pair. Great customer support for a poorly-designed product. The filter nonsense quickly got old. First one filter got clogged, then the other. When I ran out of the extra filters provided, I finally pulled out the filters entirely. That actually worked fine so you have to wonder what the point of the design of the filters are.
