Nothing wins unanimous praise in the audiophile world, but the Stax SR-009 headphones are currently the leading contender for the title of world’s best set of cans. These Japanese-built headphones feature an open-backed design, craftsman-made leather earpads, and unparalleled sound reproduction, for just over five grand.
Of course, you'll have to buy an audiophile-grade headphone amplifier to power these bad boys, so plan to spend another $2000 (at a minimum) there. But if you're a demanding listener yourself, you know that putting your money where your ears are ain't cheap.
