Which DT 880 do I have?!?

Hey guys, so stupid thing, I found a pair of DT 880's on ebay, they had a broken right channel, because the cable is loose, and the guy was selling cheap. So I haggled down to $70, and purchased them. I plan on fixing the cable, and then either keeping or reselling, not sure yet. However, the guy didn't know what impedance they were! So, how can I check what impedance they are, once they arrive at my house :)

 

Are the drivers, different?

Can I use my Multimeter/OHM-meter?

 

Beyer has been non-responsive to my various methods of contact.

 

Thanks guys! gs1000.gif

I think it is indicated on the flat rubber surround on the plug.  If you have dark blue surround on the red screens, it is 32 ohm.

And if the plugs blank, its 250 ohms.

Heya,

 

The drivers shouldn't be different. The voice coil is where they are introducing the impedance flavor. Beyer marks the impedance on the TRS termination of the stock cable. If you have none of this to go by, you can probably figure it out just by playing it back on various devices and seeing if it requires a lot of voltage to produce sound or not. If it plays back effortlessly with extended bass off a cell phone for example it's probably 32ohm. If it's harder to hear things and dimmer on the same phone, then maybe 250ohm or 600ohm. From there, just test off higher voltage sources like amplifiers to see. It's going to be hard to know the difference from the 250 & 600 ohm because they both nearly sound the same and behave nearly the same on amplifiers. So you'll have to just find a serial number or something and look it up if your cable doesn't have it marked.

 

Example, notice this 600ohm DT880 has it's impedance printed on the termination of the cable:

 

 

 

Very best,

Very best,

Thanks! Exactly what I needed, it is stock cable, so I will check that when it comes, thanks so much!

So in the picture it's black, so immediately that means its not 32?

If the framing is black, it might be the PRO version which is 250ohm.

 

Very best,

Oh are all the PRO's 250! if so, problem solved, as it is a pro! Awesome, 70 bucks for the 250, not a bad deal lol

You can just check resistance with your multimeter. It won't be exactly 250 ohms but they will be close, and that's all you need.
