High resolution sound, in the comfort of home High resolution audio Over-ear Deluxe memory foam cushions Powerful 50mm neodymium drivers for wide yet precise range Each speaker is carefully handpicked, tuned and tested, and is being paired for the most detailed natural sound. The 50mm drivers utilize high power neodymium magnets to reproduce all your music #39; #39;s dynamics and deliver well balanced crisp bass, transparent mid-range and pristine high frequencies. Acoustic open-back architecture for pristine audio fidelity An acoustic open-back architecture eliminates air pressure build-up behind the driver, allowing the diaphragm ample free movement, greatly enhancing sound transparency and smoothening extended high frequencies. Layered motion control diaphragm delivers precise sound Layered Motion Control (LMC) drivers feature a multi-layered polymer diaphragm that encases a layer of damping gel. These layers form a flexible boundary and - together with the gel - absorbs and dampens any exaggerated frequencies, resulting in a smooth and flatter frequency response. The result is a more balanced, natural and refined range of high frequency sounds. Pre-tilted drivers fit the ears for minimal sound reflection The earshells are engineered to tilt at 15 degrees, fitting your ear #39; #39;s natural geometry and immersing you in a truly precise and unadulterated sound performance. Audio signals are directly channeled into your ears, creating a dynamic and authentic listening experience.
