Hi all, jumping in here to infuse an alternate recommendation. Rarely does a thread starter do such an about face, but life can be unpredictable.
Recently after demoing over 100 closedback headphones at a specialty headphone shop in Osaka, I've adorned the Focal Spirit Classic as my all-time favorite mid-tier closed headphone. Putting it directly up against well and lesser known rival closed cans from Shure, Sennheiser, Fostex, Beyerdynamic and many many more, demoing on a fairly decent DAP setup and comparing my top picks on higher caliber solid state rig, I was quite awestruck at how mightily these beasts compare to basically every other closedback out there.
The Focal Spirit Classic are a very neutral closed can with PRaT and tonality that are hard to fault, and a very robust bass and dynamics, good isolation and above all a very non-fatiguing sound. For my tastes this puts it quite a notch over all the TH X00 variants. At first I was drawn to the Ebony because of the highly detailed, resolving and realistic sound... fast forward a lengthy audition to a loner pair of all three X00's I came to notice these are all somewhat boosted in the bass to a greater or lesser extent, and that upper detail I heard, while great in its own right, seems quite hyper-analytical especially on the Ebony and somewhat on the Mahagony. OTOH, the Focal Spirit Classics are very proper, robust and a lot more neutral with more isolation and not fatiguing. You can read more on the Classics thread here:

Though I would agree these are all somewhat V-shaped to a greater or lesser amount, interestingly the Ebonys also manage to get very liquid, lush and full mids at the same time. In fact all TH-X00s have build quality that far exceed the Focal Spirit Classic - solid wood and high quality metals, etc. vs. the plastic body of the Classics that (can) be prone to breaking. Even possibly they could be technically superior in some ways. But for my tastes at least, the Classics suit me much better - enough to finally satisfy my 10 year quest for the perfect closed headphone.
Someone also mentioned the Senn. HD 25-II, which was also one I compared the Classics to. I would say these are definitely a solid contender for portable listening, but are far underclassed by the control, frequency response and overall overall reproduction of the Classics. I also thought both the OPPO PM-3 and Beoplay H8 (IIRC) competed quite well with the HD-25-II. All sizes of the V-Moda M80 and M100 to me fell short of th former due to being fairly dark and non-detailed. but the closest match I found to the Classics were only the Senn. HD569, yet still falling short on bass control.
Not trying to completely dispel the Fostex variants, in which are superior in some ways such as build quality, and can be better depending on one's sound preference - I'm just a somewhat frank user wanting to give an alternative with a very underrated closed headphone. And in fact, the Focal Spirit Classics are recently discontinued so you just might be impressed with one of the used pairs floating around. They also scale quite well, and one owner who also has the open Focal Utopia still enjoys the flavor of the Classics.
