Similar but somewhat lighter than my 650's and therefore slightly more comfortable, and work great with the on-board/limited amp power from a higher end Gigabyte mobo.
With regard to the 650's, the one thing I've picked up on in this thread is that they likely need high quality amplification; all that I've so far used with my 650's is the amp of an Asus Xonar Essence sound board, which is not all that high end. Whether it's worth it (to you) to spend more money on better headphone amplification (than what your receiver has) is unknown to me, and I do not feel any need to go there anytime soon for myself.

How does the sound quality sound on the 595's compared to the 650's with your current equipment? Have a great day and thanks again.
I haven't really done a fair comparison as the "amp" I used for the 650's was that built into an Asus Xonar Essence PC sound board.
I can add that while I'm normally very focused on SQ, it's become clear that headphones are the exception, and that with headphones comfort/convenience take precedence over SQ (at least so far as the SQ of a lower SQ headphone is close).
At the moment my focus is to build several home theater PC's for myself with compressed .flac stereo files (16/44.1). I started off thinking I'd build 2 or 3 PC's for personal use but that's ballooned to 6. For some insight into that see my "Build a Small and Quiet PC For Stereo Music" thread: http://www.avsforum.com/avs-vb/showthread.php?t=1260917
Which is to say that I think that the SQ of the Sennheiser 595 headphones are a good deal (compared to the 650's that I have) and easier to use (less demanding of amplification) and slightly more comfortable.
But I don't plan to sell my 650's as odds are that I'll figure out a way to use them with better amplification. For one thing I've 2 extra unused stereo amps lying unused that I can plug in to try. But don't hold your breath for me to actually take the time to do that, let alone report on it.
