We believe in giving high-performance audio enthusiasts the purest headphone listening experience possible, even when their surroundings are far from perfect. The closed-back HD 620S caters to this audience by providing distraction-free listening without compromising on natural presentation. The reference-grade 42mm transducer and ultra-light 150-ohm aluminum voice coil deliver exceptional impulse response, bringing the listener to the front row of their music.

Even in complex music, bass, mids, and vocals are delightfully layered with distinct instrumentation and nuance. The steel-reinforced headband sliders and earcup covers ensure long-term durability while reducing unwanted resonances, all in a lightweight chassis designed for all-day use. Supple artificial leather earpads offer both a comfortable touch and superb acoustic isolation. The HD 620S includes a detachable 1.8 m twist-lock cable with a 3.5 mm plug and a 6.3 mm adapter. It's also upgradeable to an optional balanced cable with a 4.4 mm plug, seamlessly integrating into high-performance audiophile setups of all kinds.
