Sennheiser HD 600 Open-Back Audiophile Headphones

The Sennheiser HD 600 are known around the world as one of the most accurate and transparent circumaural open-back studio headphones available.

The acoustically transparent earcup design helps create a wide, open soundstage that mimics the feel of high-end monitoring speakers.

Comfort is equally prioritized. The lightweight build, plush padding, and detachable OFC copper cable make the HD 600 a perfect choice for long listening sessions in the studio or at home.
