Edit: The novelty of my SRH940's excellent critical listening capabilities has worn off and I think my HD 650's are perfect for long term listening still. My HD 650 and SRH-940 make a perfect pair, satisfying options for closed (Shure) and open (Senn), analytical/forward (Shure) and smooth/refined/subtly detailed (Senn). I'm going to keep both as a complementing pair. Still, this thread at least serves as a helpful reference for some good detailed open headphones if I ever do choose to buy some open headphones to complement my HD 650.
Edit 2: Oops. Seems I couldn't resist buying AD2000's (which should arrive soon) :D
Edit 3: AD2000s were ultimately unimpressive and I sold them. SRH940s still won vs. AD2000s and HD650 in highs and detail. HD650 was superior to AD2000 IMO.
Currently I have a Sennheiser HD 650 and Shure SRH940 (with an Audio-gd NFB-12 DAC/Amp).
I really like the emphasized detail the SRH-940 provides, and the relatively flat sound signature is a nice complement to my HD 650's. However since they're closed and a bit uncomfortable, I'm thinking of getting some more open, comfortable ones also. My SRH940 will be my headphones when I need isolation, my HD 650 is good for soft smooth non-fatiguing sound, and maybe a third pair for comfortable listening with a bit more detail than my 650's.
AKG-701's come to mind, but I've heard that they're a little on the uncomfortable side and don't sound as nice as the SRH940. I was considering HIFIMAN HE-300, but I heard that they're not nearly as detailed as the SRH940.
Basically, my SRH 940 is pretty much perfect sounding to me, for critical listening, except maybe it would be nice if the high treble were toned town just a bit. So, any recommendations of comfortable open headphones that might work for this?
