Dear List,

    Hello, I am wondering if anyone knows the calibration specs for
Sennheiser HD 495 headphones. If anyone uses these headphones, I would
also be interested to know how variable these headphones are across
units. Does each set need to be calibrated individually, or are they all
built the same?

thanks in advance,
