It makes all the right noises
The predecessor to these pair of cans, the Sennheiser 800S, was anti-social because the open-back headphones would mean that the person next to you could hear a great deal of what you were hearing. The HD 820 seeks to remedy that with the German audio specialist now covering the outer surface with a Gorilla concave glass case. Beyond vanity, the glass case also means lesser resonance and reduced ambient noise feeding into your cranium. Also, the new ear pads are made of a mix of leather and synthetic fibre and are entirely handcrafted.
