How the Kaiser 10 will handle Metal?
I know it's a dumb question, but some headphones (full-size mostly) just can't handle the massive sub-bass of the double bass-drums playing with two guitars and growls in the same time.
No, even the "metalhead" can SR325is can't handle that. I think dynamic drivers are just, silly and slow... and I consider a good multi-driver BA like the Kaiser 10 for that and other music with a great amount of sub-bass and mid-bass, but not exaggerated.
Anyone tried Metal with the Kaiser 10?, at least Metallica?
I'm sort of a metal head. Not all the way though - I don't have the requisite long hair and black T-shirt with obscure band logo. But still....
K10 does a fantastic job with the bands I like. Over the past few weeks I've enjoyed Obscura, Metallica, Living Sacrifice, Iced Earth, King Diamond, Meshuggah, Blotted Science, Becoming the Archetype, Mastodon, Suicidal Tendencies, and quite a few others. The K10 keeps up with fast double-bass drums (I'm a drummer) like very few headphones or IEMs I've experienced. It's up there with my Stax rig in that aspect.
The Grado sound in general can be fun for metal but not so much on a technical level. They do well with guitar crunch and have punchy bass in the 100Hz region, but that's about it.
