Expert Opinion
Professional reviewers praise the HD 820 for its innovative closed‑back design, noting the Gorilla Glass reflectors, acoustic absorber system and ultra‑low distortion as setting a new audiophile benchmark. They commend its comfort, build quality and detailed imaging, while consistently warning that the thick, microphonic cable and the requirement for a powerful amp are drawbacks, and that the soundstage, though impressive for a closed‑back, still falls short of the open‑back HD 800 S.
What Users Say
Everyday users love the HD 820’s plush comfort, premium feel and immersive, detailed sound, often describing the listening experience as “plush and immersive.” The most common complaints revolve around the bulky, noisy cable and the headphones’ large size, as well as the need for a dedicated amplifier to drive the 300 Ω impedance.
Common Complaints
Thick, microphonic cable that picks up handling noise; requirement for a powerful 300 Ω‑capable amplifier; large and bulky form factor that may not suit smaller heads; lack of wireless or ANC features.
