Non-powered sub headphones

[ChampN252]

Like the title says, I'm wanting to know of some headphones with subs that are non-powered. My buddy has a pair of skullcandy hesh that he'll let me get. They sound great and have car sub-like bass. I've heard the build quality of them are not so great thou. I'm just wondering if there is better to be had. I've heard a lot about sennheiser's, but they're high as crap. If anybody knows of anything different or know that the Hesh's aren't fragile, let me know.
