I've had the HDJ-2000 for a few years now with no durability issues, but I tend to baby all my gear. Isolation is only average, but comfort is top notch which is why I've kept it as my main portable after all this time.
The V-modas definitely have great durability, though the cords will fray over time. Sonically the M80 is the more balanced sibling and cleaner through the mids. The M-100 sounds weird to me, though would be more suitable for DJ'ing with it's compactness and more V shaped sound. Neither has a swivelling earpad if you tend to DJ that way though, and isolation is below average as well since they have those rather large cup vents that let in a lot of sound.
The Ultrasone DJ1 is... odd, and I'll just leave it at that. Either you like S-Logic or you don't. Good build quality and isolation though, as with all ultrasones.
The HD25-1-ii is solid and reliable, isolates very very well, and is (relatively) easy to fix. The sound quality is good throughout and is mildly V shaped which is ideal for DJ settings. The amperior is slightly better in all respects, though I'm not sure if it's worth the price premium. On the other hand, refurbs of the Amperior are common and very reasonably priced.
The Audio Technica Pro700mk2 is a fun head-shaker. It's also the same headphone as the Denon HP1000 (though the latter is actually more expensive).
Shure 750/840 are decent, and build quality is good even though they feel plasticky. They are very top heavy in the headband though (especially the 840), which affects fatigue. The 840 pads are great though, and I'd recommend getting some of those pads to swap onto any other headphone you have.
Audio Technica M50... it was stupid popular around these parts for a very long time, and for good reason. Personally I didn't quite like it, but it has solid performance and durability. Isolation is good, though lags behind the Shure 840 and Senn HD25. Sound is mildly V shaped like the other options, and quite clean throughout.
The Beyerdynamic DT1350 is quite good, but there are reports of high driver variability. The pair that I used to have were very good and had a very neutral (and somewhat sterile) sound). Isolation was the best of everything mentioned so far, and arguably the most neutral sound as well.
Aiaiai TMA-1... ugly sounding one-note doof in the bass sums this one up.
A dark horse pick would be the AKG K181. Great isolation and build, compact, and pretty darned cheap compared to the rest. The smaller K81/518 is similar and can be found for under $40 which is awesome.
I've gone through others, but these are the ones I've owned or had quite some time with in the past. Out of all of them, the only one I still have is the HDJ-2000.
