Releasing something as universally well-regarded as the HD 600 would usually be enough for one person to call it a day and stop innovating, but Axel Grell—Sennheiser's former managing engineer in charge of audiophile headphones—kept on creating, deigning to give us the immortal HD 650 and the immensely popular HD 800.
