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.
The deep, almost magical stereo imaging of the HD 820 is the sum of the exhaustive engineering poured into it
Developed in Germany and crafted at our state-of-the-art Ireland plant, its fit and finish is second only to its sound quality. When combined with the ring radiator’s superlative response, the driver’s angle allows you to locate voices, instruments, and their inherent environments. The sound field expertly balances realism and escapism, transporting you to the heart of your favorite recordings and nowhere else. The luxurious ear padding and progressive articulation points form a satisfying seal, eliminating distractions for added focus during extended listening sessions. For critical listening tasks and private listening alike, the HD 820 prevents unwanted sound from coming in or bleeding out.
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.
