Sennheiser announces new HD 820 flagship headphones with Gorilla Glass contains
Not many brands attempt flagship-class closed-back earphones.
The reason is quite simple. With regard to their enclosed ear cups, it is difficult to get rid of unwanted resonances and distortion. That's why most, fully flagship-class headphones have open buttocks.
Sennheiser wants to change that and they’ve just announced the new HD 820 closed-back headphones at CES 2018.
Essentially, the HD 820 is a not open back version of the seriously acclaimed HD 800 Ersus.
From the outside, unless you look closely you could possibly even mistake the HD 820 for the HD 800 Azines. But look carefully and you may see that there is a glass handle over Sennheiser's famed Ring Rad transducers.
The glass cover is actually a patent-pending curled piece of Gorilla Glass that has been designed to represent sound waves emitted by the back of the transducers into special absorber spaces. The end result, according to Sennheiser, is astonishingly low levels of resonance.
If Sennheiser's remarks are to believe, the HD 820 will give its owners higher freedom of enjoying high-levels with audiophile-quality sound.
I had a short focus on them at the Sennheiser booth and while show floor listening circumstances weren't ideal, I was gob smacked by the soundstage offered by the HD 820. It seems that the addition of the tumbler covers have done little within diminishing the HD 500 S' legendary soundstage.
The Sennheiser HD 820 will go discounted later in summer and priced at an eye-watering US$2399.95 (~S$3201), which makes them quite a fair bit dearer than the High 800 S (US$1699.95). The great thing is that at least you have the next couple of months to start saving up.
