Sennheiser HD 820 is Sennheiser's top of the line headphone, a flagship closed back design with a cutting edge combination of clarity, spaciousness, comfort and lifelike dynamic sound quality.
HD 820 uses a unique glass cover and absorbers to control airflow and reflections in the headphone, in order to provide the most open, wide and accurate sound possible while providing isolation.
HD 820 is similar to the HD800s, but with a different housing, deeper, more isolating ear pads, a very posh black stained wood storage case and two cables - a 6.5mm and 4.4mm balanced, 3m cables are both included. The cables are precisely matched in impedance and low capacitance, making them the perfect accessories for the HD 820.
