The HD 600 is the audio purist’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, it is globally recognised as the standard for analytical high-fidelity listening - even 20-plus years after its release. The foundation of the extraordinarily clear sound of the HD 600 is its’ open acoustic design and the revolutionary transducer, which has been computer-optimized to reduce partial vibrations, which are responsible for a multitude of distortions. | Sennheiser | | HD 600 | Hi-Res Audiophile Open Back Headphone | Pioneered with Controlled Airflow and Optimised Transducer | Black | Best Buy
