The EQ-7 are pretty nice for metal, I find; it's an interesting sound signature. I use them when outdoors, and use IE8's inside, because the sennheisers don't isolate too well. I wear the Ortofons over the ear, I've never actually tried them cable down. My ear canals point downwards, so I point the EQ-7 at an upward angle when I put them in, and they slide pretty easily. If I put them in straight horizontally it will take a few tries. I would describe my canals as medium size, not large, but don't have fit issues, and would not describe them as uncomfortable. The are not as comfy as the IE8, though. I also find that pushing them too far in will muddy the bass, but pulling them out barely a millimeter fixes it. I would describe the Ortofon bass as punchy; if you enjoy bands that have good bassists and audible bass lines, you'll love them. I was listening to Atheist, Cynic, Kyuss and Pestilence on the train yesterday, and it was still coming through pretty well. Drums will also have a nice impact sound/texture, and I'm really loving the cymbals.
Build quality seems pretty solid; they are essentially hollowed out alluminum tubes. I'm not fond of the corded cable (computer mice have them too now, the kinks never seem to come out). I also dislike that it doesn't have an L shaped plug, almost a dealbreaker for me, and not having a cinch is just bizarre; no reason not to have one on an expensive phone. On the other hand, Monster's offerings are just plain foul looking. I don't care what they sound like, I'm not a pimp out to get his money from his ho's. The Ortofon is elegant looking, and sounds great. I would not be seen in public with the Monsters.
Hope this helps, I've had these basically since the first week of march, so i have a fair amount of time on them. I actually think they've warmed up slightly since then, but I've loved them since I first put them in, and my opinion hasn't changed.
