i did use a set of those ASA headsets.....let me just say you get your moneys worth...the only thing that made it worth it is that i was just borrowing them from a friend...after having used them for several months i constantly got a headache from them....i finally got a pair of DC's for my birthday and would recommend them. the way i see it, id rather buy a decent set for a little more money and not have to worry about replacing them in a year or so vs...buying a cheap set, then buying a better set down the road...you spend more money...just buy the DC's
