Great for instruments & producing
These headphones are world-wide renowned for being honest and faithful in their music reproduction. Particularly fantastic for classical instruments such as the piano, they are also great for music production because of their flat frequency response. Their only downside is 1) comfort was not the highest priority and 2) I own a pair of vintage Sextett K240's, and while requiring a LOT more power to be driven, they sounded a little wider and more beautiful for lack of words. The current/modern ones sound a little more boring but again, for studio work that might be exactly what you need.
