--&gt; The K 240 DF follows the criteria specified by the Institute of Radio Technology (IRT) in Munich for a "diffuse field" equalization curve that provides headphone listeners with the sound pattern, characteristic of a room with reflective, non-anechoic surfaces. Each K 240 DF is rigorously tested to assure strict adherence to the IRT standards for frequency response, channel separation and sensitivity.<>well...
~~I have to say Monitoring Headphones 240DF is not a bad headphone...
somewhat a little bit more studio taste than Beyerdynamic DT831,Sennheiser 580&600 ...even AKG 501~<>anyway it's one of a good choice for someone...but not all...<>...just forget about it guys...
