HD 820 - The critics said closed headphones could never sound as immersive as their open-aire 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 as vivid as it is uninterrupted.
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. 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.
