Sennheiser‘s will showcase their new HD 820 headphones at CES in Las Vegas this week. What makes these headphones unique is that they’re closed back dynamic headphones with a glass transducer giving off a very natural sound. It’s made of a metal headband and a damping element and OFC cables with gold-plated plugs. These headphones have also been cushioned to insulate those listening from excessive ambient noise.

Axel Grell, Portfolio Management Consumer at Sennheiser shared, “Usually, high-end headphones require an open-back design, which has placed limits on where you can enjoy true audiophile sound. The HD 820 is a game changer that delivers exceptional sound while insulating the listener from their environment. I consider them to be the most transparent-sounding closed-back headphones in the world.”

The price for these headphones are $2400 USD and will be out mid 2018.
