Description
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 we simply said, “listen”. The HD 820 combines an innovative glass reflector and ring radiator transducer technology for a benchmark listening experience.

The HD 820 fuses our cutting-edge transducer capabilities with exceptional ambient noise attenuation, transcending the perceived limits of closed headphones.
Until now, the audiophile headphone experience could only begin with Sennheiser’s open back design—a design that paved the way for an entire class of precision listening devices. This standard of sound reproduction would go on to surpass hi-fi systems exponentially larger in size and cost with the understanding that listeners would not be isolated from their surroundings. The HD 820 sacrifices neither detail nor sound field thanks to its innovative acoustical systems in a closed, dynamic headphone.

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 favorably 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. Every contact point utilizes ultra-soft padding, while purpose-built composites reduce weight and unwanted pressure. Each earcup provides dual-axis articulation that instantly and effortlessly conforms to your head’s unique structure. The result is a listening session that never gets in the way of your passion for hi-fidelity sound reproduction.

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.
