Been checking out more stuff with them the last couple of days, and I think these headphones might renew my interest in metal. The separation is incredible for how busy metal can get, separate guitar riffs and bass and vocals all stay clear even on metal that isn't produced super well, and unlike some open cans I've used instruments are still close enough together that everything still feels cohesive when guitars are supposed to be playing off each other. Guitars also just sound fantastic on these, they're great at letting you hear detail in the tone and effects without making them overly aggressive or fatiguing.
