NEW Sennheiser HDV 820 Digital Headphones Amplifier is the next generation of digital headphones amplifiers.

Designed to complete the Sennheiser audio experience and perfectly complement its high-end audiophile headphone range for the ultimate acoustic performance.



Pair your reference-class headphones

The HDV 820 digital headphones amplifier will surely change the way you listen to and experience your music. That is, if you are lucky enough to possess headphones capable of turning the extremely high-quality audio signal delivered by the HDV 820 into an aural quality just as supreme.


The mission: Better the best

Since Sennheiser has engineered audio components that represent the state of the art, it has to be the most rewarding task to go one better. This is the task they set out on when they designed the HDV 820 Headphones Amplifier. 

Pioneering into new technological territory, they still found more sonic truth to bring to their most demanding clientele. 


The sound: Making great headphones show all their class

The HDV 820 will give your headphones virtually everything, so it's up to the cans to make it heard. 

The different timbres of two otherwise identical instruments, the distance between the musicians of an orchestra, and the tension before a singer delivers the first note. 

It is all there for you to discover. 


The technology: Only the unsurpassed

The higher the tech, the higher the emotion. The heart of the new HDV 820 is a formidable ESS SABRE32 DAC that surpasses the previous generation with an even higher resolution of 32 bits and a sampling rate of up to 384 kHz. 

The amplifier is also capable of playing DSD256 files of up to 12.3 MHz.


The design: Giving the eyes a taste of how it sounds

The HDV 820 has been created to be aesthetically pleasing. It features a new anodized black finish with white LED lights designed to perfectly complement the latest version of the flagship high-end HD 800 S headphones. 


The compatibility: Outstanding sound will find a way

The HDV 820 provides a number of audio outputs including XLR3, XLR4, 6.3mm and 4.4mm Pentaconn sockets.

It performs brilliantly with digital sources: opical, coax, USB, balanced XLR and unbalanced RCA analogue inputs.
