Acoustically engineered for accuracy The LCD-4 is far and away Audeze's most advanced headphone featuring innovative planar magnetic technology that delivers startling dynamics and incredibly open and spacious sound. Near weightless nano-scale diaphragm The LCD-4 features our most advanced diaphragm design; our exclusive nano-scale film actually weighs less than the air it displaces! Benefits include faster response times for better imaging, and the flattest, deepest, most accurate bass response of any headphone available. Audeze nearly doubles the magnetic driving force Double FluxorTM Magnet Arrays focus the magnetic flux to a previously unheard of 1.5 Tesla, nearly doubling the power driving the diaphragm for improved transient response and far greater resolution.
