Is there any way I could tell a pair of DT880's impedance just by looking at it? Are there any special marking on the cans that indicates that? The reason I ask is, if I buy a used pair online and it doesn't come with a box, there is no way I could tell if I am really buying a pair 600ohm instead of the 32ohm without trying. 
 
Although I haven't tried the 250ohm, it may seem very close to the 600ohm version if I am not too familiar with them.

The 600 Ohm will have it stamped on the plastic 1/8" plug housing.

Everyone should own a multimeter for ooh so many reasons. This is one of them.
 
You can get a DMM for like $15 from any number of sources.
