Sennheiser HD 800 S Open-Back Headphones – Black

The Sennheiser HD 800 S is a wired, open-back over-ear headphone for home listening and critical evaluation. Its 56 mm Ring Radiator dynamic transducers sit in angled earcups, with absorber technology designed to reduce unwanted resonances. The open construction lets room sound in and headphone sound out, making a quiet listening space more suitable than a busy commute. Sennheiser specifies 300-ohm impedance, so pair the headphones with an output capable of driving a high-impedance load at your preferred level. Detachable cable connections support the manufacturer-listed 6.35 mm single-ended and 4.4 mm balanced arrangements; balanced use needs a compatible output. No particular amplifier is included or mandatory by name. This listing is the Black HD 800 S alone, not the HDV 820 bundle or a closed-back HD 820.
