This were my first "real" headphones and now I'm building a Mosfet Mini Max tube amplifier and DAC, buying parts, modding my headphones, etc. All in three short months. These will turn you into an audiophile. The clarity from these are just wonderful. Rich, full mids, wonderful treble response (perhaps too wonderful...at times they can be very bright and tinny, but usually not) and a good low end too. This is, of course, pre-modification. With the drivers vented, new grills, new headband, custom wood cups, G Cushions and the driver cloth removed...
