 Sennheiser HD820 Closed Dynamic Headphones

 

The new audiophile standard

The critics said closed headphones could never sound as immersive as their open-air counterparts. They said physics would never allow it. To that Sennheiser simply said, “listen”. The HD 820 combines an innovative glass reflector and ring radiator transducer technology for a benchmark listening experience.

 

Completely closed. Outrageously open.

The HD 820 fuses our cutting-edge transducer capabilities with exceptional ambient noise attenuation, transcending the perceived limits of closed headphones.

 

Reflecting within

A closed back headphone able to produce the wide, natural sound field of an open one requires rethinking the directional characteristics of sound waves.

 

Fellowship of the Ring

An achievement in its own right, the 56mm ring radiator found in the HD 820 leverages the key benefit of a large diaphragm transducer—air displacement—without losing the rigidity that favourably impacts rest and response times.

 

Exhaustive engineering

The deep, almost magical stereo imaging of the HD 820 is the sum of the exhaustive engineering poured into it.

 

An Ergonomic Treat

The HD 820 delivers on long-term wearing comfort too, providing a listening experience as plush as it is immersive.

 

It's all about connection

As a centerpiece of your constantly evolving rig, your go-to headphones should offer the versatility to listen on your terms.
