SENNHEISER HD 820

Sennheiser's HD 820 headphones redefine standards for audiophiles, challenging beliefs about the limitations of closed headphones. They integrate glass reflector and ring radiator transducer technology to provide an unprecedented listening experience. Despite the closure, they maintain a large sound field thanks to concave glass precision reflectors, offering a sound similar to open headphones. The 56 mm ring radiator uses a transducer with a large diaphragm, ensuring stability and precision in the response to frequencies. Every detail is carefully controlled, giving the HD 820 reliable performance and total immersion in music.
