The Sennheiser HD 620S is a closed-back audiophile headphone that brings the tonal refinement and musicality of Sennheiser's acclaimed HD 600 series into a closed-back form factor for the first time, addressing the longstanding demand for a Sennheiser closed-back that sounds like its legendary open-back models. It features a 42mm transducer with a refined magnet system that delivers a natural, balanced sound with the warm, organic midrange character that has defined the HD 600 lineage. The bass is full and well-extended with a satisfying weight that the open-back HD 600 and HD 650 cannot quite match, the midrange is smooth and natural with excellent vocal reproduction, and the treble is detailed yet never harsh or fatiguing. The closed-back design provides effective passive noise isolation for use in offices, commuting, and shared listening spaces while maintaining a surprisingly open and spacious internal presentation. The headband features Sennheiser's updated design with soft padding, and the velour-covered earpads provide comfortable wearing over extended sessions. At 150 ohms, the HD 620S benefits from a quality headphone amplifier or audio interface but can be driven adequately by better portable devices. Build quality is refined with durable materials and a detachable cable. These headphones are ideal for audiophiles who love the Sennheiser house sound but need closed-back isolation. The closed design, while well-engineered, cannot quite replicate the expansive airiness of the HD 600 series' open-back presentation.
