Flagship open-back headphones feature game-changing technology, like its first-of-the-kind nano-scale diaphragm with Double Fluxor Magnet Arrays that nearly double the driving power. Benefits include faster response times for better imaging, and the flattest, deepest, most accurate bass response. 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. Double-Fluxor 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. Patented Fluxor Magnet Arrays focus the magnetic flux nearly doubling the power driving the diaphragm for even lower distortion and greater accuracy. Patented Fazor Elements guide internal headphone soundwaves to avoid resonance for a more accurate waveform. The frequency range is 5 Hz – 20 kHz (extended out to 50 kHz), 15W maximum power handling, 130 dB SP and the impedance is 200 ohms. A proffesional travel case is included.
