My goals for a portable closed headphone were probably very similar to that of yours: Circumaural, highly portable, lightweight, easy to drive from the huge variety of portables I usally have.
The HFI-650 failed on two points: Portability (they're enormous even when folded), the fact that they didn't stay on my head / debatable comfort.
It succeeded on three points: Sound... punchy and lively, the ability to be used (to an OK level) with low-powered portables, and also decent isolation.
The DT250-80 failed on four points: Sound (indeterminate tonality, detail, staging and impact... bland is a reasonably accurate way to put it, yet it has a midrange hiding a surprisingly nasty bite), isolation (barely better than a PX200), portability (despite being quite low profile on the head, the fact that they feature fairly large earcups and don't fold means that they aren't the most stowable phones) and unamped use with some of the lower-powered portables.
It succeeded on one point: Comfort, although the cable kept jabbing me in the shoulder when I moved around.
The HD25-1 is despite the potential sweatiness of the supraaural fitting something to be considered IMO.
The HD25-1 failed on one point: Comfort (supraaural clamping feel means that you sweat a lot. In terms of actual pressure put on the head it's not as bad as I expected after a while).
It succeded on four points: Sound (Slightly claustrophobic souldstaging notwithstanding it's very entertainingly punchy and more importantly clear), portability (durable and compact), superior isolation and the ability to be used unamped from portables with even 0.5mw of output.
The SE-Monitor10R is something I haven't tried.
