Serj Tankian has a ground loop issue with his vocal mic, you can hear the extra tiny bit of buzz where he cut in the vocal track on elect the dead. If that doesn't say it then I don't know how to. If you have an amp to use with them, buy them, just like that. They don't sound great without a proper headphone or integrated amp, but with one, step back there's a show going on. They don't punch bass, but they will go exceptionally low very cleanly. "Bass I Love You"'s 7Hz low is able to be perceived. That is low for an open back set with such a huge soundstage. Where they really shine is on acoustic tracks where there are all kinds of little sounds, picks plucking and singers breathing, and feet moving, that just gives you a huge stupid grin.
