Until now, audiophiles had to choose between the immersive experience of open-backs or the isolation of closed-backs. Now, get the best of both worlds with the Sennheiser HD 820. It retains the privacy of a closed-back while reproducing a wide and natural sound field.
Put a Ring on It!
A 56mm ring radiator uses the driver’s air displacement without losing the rigidity that impacts rest and response times favourably. The inner and outer edges of the rings are secured to the driver. The voice coil vibrates the diaphragm, connected to the V-shaped groove found near the centre of the ring. With this combination and a unique driver angle, you can easily locate vocals and instruments in their environment for the sound that transports you to the heart of a recording.
Beautiful – in Looks & Sound
On the outer plane of each ring are precision concave glass reflectors that prevent the redirected sound waves from creating resonance and distortion. These reflect the energy created by the driver to a specially tuned absorber system, allowing the waves to mimic the behaviour exhibited in open-air models such as the HD 800 S. While also a striking visual feature, the technical execution of the glass reflector yields a soundstage never before experienced in a sealed headphone.
Engineered to Perfection
The magic of the Sennheiser HD 820 can be felt via thorough attention to detail. Each driver is engineered and rigorously tested to give you a spectacular performance right outside the box. Each model includes the frequency response plot unique to that set’s serial number. The vibration-damping chassis and inert headband insert provide complete stability while the luxurious earpads form a satisfying seal for perfect comfort and noise isolation.
Connections that Matter
Your preferred headphone should be versatile – perfect to suit your ever-evolving set-up. The HD 820 comes with 3 meters (9.8 feet) cables with a variety of terminations. These include the audiophile standard 6.3mm (¼-inch) and balanced 4.4mm connectors that can seamlessly connect to audio devices like headphone amplifiers, DACs, A/V receivers and more.
