I own a BeyerDynamic DT 880, I lost my original receipt, how do I find out  how many OHMS my model has?

If you gave access to a digital volt meter with the resistance setting, you could check manually by testing for resistance across the 1/8 plug.

Should be stamped in the plastic housing of the jack on the flat spot. If there is no number there then it should be a 250, but the ohm meter will tell you for certain.
