I want headphones that are GOOD FOR METAL and can also do good for other genres for around 150 and they must go around my ears.
Also are these any good? ULTRASONE HFI-2400
Do these headphones need to isolate or contain their music? I ask because you mention "school."

That said, the HFI-2400 are very good, yes. Compared to the Grados they're a different beast - darker, bassier, more spacious sounding. But like the Grados - completely open. Makes them a no-no for use on trains, planes, and automobiles, as well as places like libraries (they leak too much noise in and out).
For what you're describing, the DJ100 are a good choice honestly (and they look pretty stylish IMO - black aluminum and silver accents - if it does anything for you, there's also a commemorative edition that celebrates Tony Bennett), so are the SR-80, and so are the HFI-2400 (although I like the HFI-2400 better for grunge (if there's a headphone that fits grunge as a genre, the HFI-2400 are as close as I've ever found)).
When it comes to the Beats, the only ones around $150 that I'm aware of the on-ear model, and they sound hideous (it sounds like you're listening through a woofer with no LPF); nothing I'd want to listen to guitars and wailing on. I have less of an opinion about SkullCandy - I (unfortunately) have experienced most of their original headphones, but that is apparently a bad reference compared to some of their newer models.
I'm guessing within your price range, some of the closed Ultrasone models would be suggestable, but I haven't heard any of the modern ones (like the HFI-780 for example); just based on the brand's reputation and what I have owned from them, I'd say give'em a look, look for reviews, that sort of thing. There's also the Ultrasone Fan Club thread that you could ask in - I'm sure someone there will be able to better guide you regarding the newer closed models.
As far as the lack of testing - I'd say go with Amazon.com if you can; their return policy is bulletproof, and you should have no issues sending back a pair of cans if you're unhappy.
