The Sennheiser HD 820 headphones have ring radiator transducers that are fitted using specialized glass covers. These glass covers not only show off the technical parts inside of the headphones, but they are designed with the purpose of enhancing the sound. Because the glass is concave, it reflects the sound waves from the back of the transducer up to the absorber. This helps minimize the resonance in the chamber and takes away the sound waves that are still present in open headphones. Exceptional levels of detail are given to each pair of these Sennheiser’s, ranging from everything like the handcrafted, ergonomic ear pads to stop ambient noise from getting in to the gold plate plugs and silver clad OFC cables and the ultra-durable metal headband with a dampening feature.
Designed for the audiophile that wants to experience their music in perfect quality and fidelity, the Sennheiser HD 820 headphones are unique, closed-dynamic headphones that are ideal for wear at home or on the go. These circamaural headphones feature an open-back design, one that affords them a closed-dynamic listening experience that makes each note of the melody sound crisp, natural and totally transparent. Made and developed in the heart of Germany, the sound is incredibly realistic. Wearing these comfortable microfiber ear pads only aids in the blissful experience of wearing the HD 820’S. The secret to the incredible sound of these speakers is its wide-open design.
