They also have a stunning aesthetic quality due to the Japanese lacquer, Urushi, that is used on the housing. ## Technical Specifications Type: Dynamic Driver:  50mm diameter Neodymium magnet Impedance: 25 ohm [[Sensitivity (dBV, dBmW)]]: 100dB / mW Maximum Input: 1,800 mW Reproduction Frequency: 5 – 45k Hz Weight: 400g (excluding the cord) Cord: 3m Y type 7N-OFC Plug: 6.3mm diameter stereo phone plug
