So, my question is. Does someone else know any more hints on how to drive this IEMs with heavy metal? (it is really sad to have such a high end IEM that can't deliver your favorite genre).
There is nothing you can do other than tape mod, don't believe in cable nonsense and no point in amping such as low impedance extremely sensitive earphone, you can just make it worse with it. Of course you can play a bit with equalizer but they sound like they sound... Changing the tips might give you better seal = bit more rumbling bass but better isolation, anyways that wouldn't exactly help with sound itself, if it's slow will remain slow :/
