Some people say they're less detailed. And the slow bass was also something I'd like to avoid, I could really notice that with the m50s when I had them at the same time as the hd600s. I really like the detail I can get from the hd600s and DBA-02s, but the hd600s have even less bass the dba-02s lol. I've never actually tried the hd650s, originally I was going to buy them, but then picked up the 600s on impulse and I am pretty happy with them. I was going to decide what to do once I build the bottlehead crack I ordered, but if these Fostex's can possibly have near the 600s detail with more impact/bass presence then I'll be a happy camper.
