Sennheiser HD 800S Open-Back Audiophile Headphones | 4Hz–51kHz | Made-in-Germany Flagship
Product Introduction
The Sennheiser HD 800 S is an open-back flagship headphone built for audiophile listening: 56mm ring radiator delivers an ultra-wide 4Hz–51kHz response, 300Ω impedance for flagship amplifiers, and THD below 0.02% for a distortion-free stage. This is a parallel-import unit; 1-year warranty provided by DIGIBAL ONLINE. Note: open-back design leaks sound, best for private listening spaces; a headphone amp is recommended to get the most out of 300Ω.
