Sennheiser headphone impedance (1 Viewer)

[Christopher Chung]

I been reading a lot of posts from the search function about the Sennheiser 580's and 600's since I am in the market for a pair. But nobody has commented on the 590's.
Since the 580 and the 600 have a nominal impedance of 300 ohms, less power is pumped out to the phones unless you have a headphone amp, correct?
Now the 590's have a 120 nominal impedance (unless I am mistaken) so wouldn't that mean you'll get a little more "umph" out of say a reciever's phone jack, since it can pump more energy to it?
Just had to ask this since I don't really want to buy a headphone amp. Thanks for any help!!

I have the 580s which are 300 ohms. About 3 months ago I tried out the 590s (120 ohm). The Headphone output on my Yamaha reciever had no problem powering the higher impedance 580s but had a hard time runing the lower impedance 590s. I guess it just ran out of juice with the lower impedance phones. One things for sure the 590s cant hold a candel to the 580s in terms of sonic bliss even when the 590s were driven from a headphone amp.

Go with the 580's. They are the best unless you can find the 600's for
