No real critical listening to them before, I've just taken a gander on a occassion at a friends place. Can't even think of the make/model.
A part of me hopes the average consumers take a liking to this sort of thing and purchase it, it'll drive demands and innovation for newer / better versions which one day might have a prayer of competing with their non-wireless counterparts. The other part of me dreads this as well, as the price will likely remain high for a long time because wireless seems so "new" and "cool" and whatever other buzz word you can attach to the slogans marketing will sling at us.
Unfortunately, these things are a long way off to satiate the average audiophiles demands for quality and performance.
