On the box in print, it says "250 ohm." However, there are stickers on the box that state that these are the 600 ohm version. Is that legit?
 
I got them from b&h so I have no worries. I just wanted to make sure that the 600 ohm owners have the same.

look on the plug.  the ohms is written on that.

oooh

To be absolutely sure there is  a way - measure impedance using multimeter.
For your information, you should know that there will be flowing low voltage through drivers 

 
 
 
EDIT Ah, you have already got the answer. Anyway, this idea will be for future

well?  were they 600 or 250???

That's cool, what amp are you using for them?

Hmmm,nothing on my plug,i bought mine used,cant find any i.d. on the phones themselves,but i do have to turn the volume up a little when i swap from 300 ohm hd650's.

check the cable on the junction going to the headphone cups, it should be written on the inner side of the cable if its 600 ohms...

I also got these from B&H.  Very nice of TheWuss to give the heads up about the plug.  Mine says 600 ohms.

I can't find any markings on my pair that identifies them as 600ohm,i even popped out the driver ,nothing there either,apart from a yellow line on the back of the driver.
could these markings be something introduced fairly recently?.

I took a picture of my DT990 600ohm awhile back, something told me I should take a picture of it, guess you were the reason why
 

 

[wasp131]

Thx,lxxl,
They look the same as mine, but mine don't have the resistors seen in the pic ,just the wires.

 

[lxxl]

hmm, maybe a 250ohms, need a 250ohmer to confirm.
 
FYI, both of my 600ohms have the resistors.
