I can back up the recommendations on the Audio Technica M50 and the V-Moda M80 in regards to durability. I currently own both of those and they're both super durable. They are also, however, very different headphones.
The M80s are consumer oriented phones. You'll like them because they're freakishly durable, have surprisingly deep bass for on-ears, and come with shorter (mobile) cables more oriented for your usage. Their cables are also removable/replaceable, which I am a major fan of. I don't really enjoy their sound personally because I feel they're a little harsh in the upper frequencies. Comfort wise the reviews are 50/50; my personal experience was that they put too much pressure on my ears (pressing them flat) and I couldn't wear them for more than 45-60 minutes, if that.
The ATs are branded as studio phones but are oftentimes used by Head-Fi users as a portable due to their (relatively, for studio monitors) short, coiled cord and fairly even frequency response. You'll see these reviewed as everything from bright to bassy and everything in between. My experience was that they have a relatively even response with a little extra kick to the bass that doesn't bleed terribly into the mids, but they're relatively flat sounding because of their intended use (you want flat if you're mixing, obviously).
I'd also like to half-heartedly throw into the mix the Sony MDR-7506/V6. Those are also a pair that I own, and they are relatively neutral much like the ATs, but instead of the extra emphasis on bass of the ATs, the Sonys have slightly boosted treble. Some people find it fatiguing, but I don't, and I find them to be more enjoyable to listen to with most genres than the M50. The coiled cord is a long one on the 7506, though I don't know about the consumer-marketed V6 (the 7506 is the "pro" studio model).
