Sennheiser HD 820: Experience Audio Like Never Before
Imagine this: You're sitting in your favorite chair, eyes closed, the world fades away as you're enveloped in an ocean of pristine sound. The Sennheiser HD 820 is here to transform your listening experience into something truly extraordinary.
Developed and manufactured in Germany, the HD 820 is not just a headphone—it's a masterpiece. With its closed, reference-grade design, it offers audiophiles an experience as vivid as it is uninterrupted. But what sets it apart from the rest?
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.
Exhaustive Engineering Meets Luxurious Comfort
- Crafted with precision in Germany and assembled at our state-of-the-art Ireland plant, the HD 820 is a testament to meticulous engineering. Its design is not just about aesthetics but is carefully curated to enhance the auditory experience.
- Deep Stereo Imaging: Experience sound so real, it's like the artist is performing just for you. The driver’s angle and ring radiator allow you to pinpoint voices and instruments in their exact locations, creating a soundscape that balances realism and escapism.
- Luxurious Ear Padding: Comfort is key, especially during long listening sessions. The HD 820's ear pads are not only plush but form a perfect seal, blocking out distractions and keeping you in your sonic world.
- Isolation at its Best: Whether you're in a bustling cafe or a quiet room, the HD 820 ensures no unwanted sound comes in or bleeds out, making it ideal for critical listening tasks and private enjoyment alike.
- Zero Compromise. The HD 820 fuses Sennheiser's bleeding-edge acoustic capabilities with exceptional reduction of ambient noise. Until now, the audiophile headphone experience could only begin with an open back design or loudspeakers. The HD 820 sacrifices neither detail nor sound field by using breakthrough acoustical systems in a closed, dynamic headphone.
Reflecting Within
The reference-class experience of the HD 820 is achieved with the use of precision concave glass reflectors, one capping each earcup. These functional plates reflect energy from the rear of the driver to a specially tuned absorber system, allowing the waves to mimic the behaviour of open headphones such as the HD 800 S. The result is a sound stage never before experienced in a sealed headphone. The headphone’s vibration damping headband provides complete stability while reducing crosstalk. What you put into the HD 820 is precisely what you will get out of it. Each transducer is manufactured, examined, and measured to an extremely tight tolerance to ensure the most dependable performance out of the box. Each HD 820 also includes the frequency response plot unique to that set’s serial number, sparing no resource to help you retrieve the most critical details from every corner of your music collection.
Fellowship of the Ring
The 56mm Ring Radiator transducer found in the HD 820 leverages the key benefit of a large diaphragm speaker—air displacement. Both outer and inner edges of the “ring” are secured to the drive unit to keep it rigid for fast rest and response times. The result is accurate response spanning the entire frequency spectrum.
