Looking for headphones that swivel flat

I love my Sennheiser hd650, boy it would be cool if I could take them with me.  But they won't fit in my laptop case.

You know what?  My M-Audio Q40 headphones can collapse but do not swivel flat, and again don't fit in my laptop case.  And in fact, I have only one that does fit-- Beyerdynamic dt660.  They are too bright though for me.

Now I'm tired of earphones, even with the comfy Klipsch S4s I listen for long enough that they bother my ears.  I am done with IEMs.  Sick of ear wax build up, tired of irritated ears.

I've tried the search function but I can't find what I'm looking for.  This is what I want:

(a) swivel flat

(b) warm, but not muddy, dark but still having treble extension (i.e. simply rolled off) just like my 650s

I hope that I don't appear to be a bossy jerk, I don't mean to be.  I appreciate you guys, this forum is a great asset for finding headphones in a saturated market.  Please help me out here.

Thanks!  I can see that I misspoke, I meant swivel flat, it doesn't need to fold up.  I'll edit the title and post and see if I get more replies.  I'm glad to have a candidate headphone for purchase (the 238).

You prompted me to search it out on your shootout... and that sounds absolutely perfect!  It collapses flat with a case, it has a warm and dark sound signature, and sensitivity low enough to not pick up on the noise from my laptop (I had that problem with my S4 hissing like mad), is comfy and isolating.  A perfect fit for me!  Thanks I'll be ordering this next week.

Yeah my Beyerdynamic dt660s have me covered on the bright side of things.

Well funny enough I decided to upgrade my dac/amp first, I got the nuforce udac-2 and now all of my headphones have more bass impact and sound smoother.  So guess what?  I have to change sound signature for the sake of synergy!  Now I'm looking for neutral, but still smooth sounding and comfy on my head. Of course still swivel flat.  Sorry to be such a nuisance.
