It bothers me when they call them "monitors" and then go ahead and fiddle with the frequency response anyway. Look at the difference between the HD 280 pro and HD 380 pro, both labelled as monitoring headphones. The 380 sounds like a muddy mess in comparison, with everything below around 300hz turned up way too high. I think it's fair to ask: if you're going to make MegaBass headphones, mark them as such. Don't advertise flat response and then hand us this.
