An update on the well-regarded HD 800, the Sennheiser HD 800 S Stereo Headphones comprises a pair of open-back headphones designed for use in studio situations, particularly when referencing between monitors and cans. Its 56mm transducer is housed in stainless steel, while its headband and mounting utilize industrial, aerospace-grade materials to emphasize durability at a relatively light weight of 11.6 oz. Sennheiser's proprietary sound absorber technology preserves the integrity of the highest of high ends by eliminating the "masking effect," a phenomenon in which the ear struggles to hear particularly bright signals when lower-frequency material occurs simultaneously at a louder volume. In reducing this masking effect, every nuance of the frequency spectrum is represented and made audible.
The design of its earcups directs sound to the ear at a subtle angle, thereby aiding in a realistic—and realistically stereo—monitoring experience. Additionally, there are two different possibilities for audio connection: a stereo 1/4" connector, and an XLR4 balanced cable for connecting to balanced outputs, such as a headphone amplifier.
