Sennheiser HD 800 S (Open-Back Reference Headphones)
#1 in Audiophile Headphones · Rated 4.8
Open-back reference with massive soundstage and detail
The Sennheiser HD 800 S is a flagship open-back reference headphone renowned for its expansive soundstage, highly extended treble, and highly accurate imaging. Built around a 56 mm ring-radiator driver, it aims for an ultra-wide, speaker-like sound reproduction ideal for critical listening and mixing in spacious rooms. It benefits from absorber technology to tame high-frequency resonances and requires a capable headphone amp to reach its full potential. Intended for audiophiles and professionals who want an uncolored, large-scale sound, the HD 800 S differentiates itself from many rivals with its glassy detail retrieval, airy highs, and disciplined, fast transient response. While comfortable for long sessions, the open-back design makes it unsuitable for noisy environments. This model remains one of the most enduring reference headphones in global distribution, with broad language support and robust aftermarket cables and accessories.
