With the announcement of the Sennheiser HDV820, there has been a bit of speculation and "leaks" over a possible successor the HD800S, the HD820... __________________________________________________________________ [UPDATE] The HD820 has been officially announced at CES... Current price is set to be €2,399 in Europe and $2,399.95 in the US with its release to be sometime during the beginning summer of 2018. The cover material on top of the driver is made of glass. Sennheiser claims the glass cover is designed in a way to reduce resonance by redirecting the reflected sound waves into a special absorber chamber, similar to the IE800 and HD800S I'd assume. It comes with a new set of earpad made of if synthetic leather and microfiber. It also comes with Pentaconn connector cable too instead of just a 4 pin XLR.
