The Grell OAE2 open-back headphones are an audiophile’s dream, but you have to be willing to drop $600. And I think that's worth it for some of the best headphones in the studio game.
They offer extremely detailed sound with a wide soundstage that gives the individual instruments room to be heard with complete clarity. And this clarity is prevalent across all frequency ranges. I was especially impressed by the performance at the lower end, with bassy tracks sounding very clean.
