I just snagged a pair of these on Ebay new-in-box for $37 shipped. The auction stated these were 40 ohms, but I've done a little reading here on head-fi and a couple people have mentioned that the DBI Pro 700's are 300 ohms. Pretty big difference.

I'm hoping they are as advertised (i.e. 40 ohms) as I plan to use these w/ portable devices (cd player, mp3 player, portable dvd).

Does anyone know for sure? I checked DBI's website and they don't specifically list the ohm rating for the 700's.

40 ohms. i got this from dbi themselves in an email. i asked for the specs- all i got was the ohms

I wonder where the 300 ohm rating came from? Could've sworn a couple head-fiers said they were 300 ohms.

At 40 ohms, I'll be very happy with not having to use an amp to get them to sound good.

could you tell me how is the performance of your dbi-700 pro did you need an expernal amplifier?

They need an amp even with 40Ohm impedance. They become more full sounding more controlled in highs & more pleasant overall. The better amplifier you get - the better they are. Handle tons of bass, show more great details. Very good cans considering it's price.
300 Ohm appeared because of MB quart qp805hs (model that is very close to dbi - i can say it's mother ).
