Kindly PM for latest stock availability and best price before making payment Hai Wei ** Facebook http://m.me/StarsPickerAudio ** WhatsApp https://goo.gl/GsPFak Introducing the LCD-MX4 Powered by Audeze’s patented Fluxor magnets, the LCD-MX4 focuses 1.5 Tesla of magnetic flux on the lightweight 20 ohm impedance diaphragm. It is perfect for use where one isn’t likely to have a dedicated high-powered headphone amp and can be driven easily by a laptop, mixing console or audio interface. The LCD-MX4 headphones' new lightweight design includes a durable magnesium housing with a carbon fiber headband. Significantly lighter than the LCD4 model, the new MX4 is the choice for long mixing sessions and hours of critical listening. A perfect combination of the LCD-X and LCD-4, the LCD-MX4 has the easy-to-drive diaphragm and voice coil of the LCD-X combined with the extreme magnetic force of the LCD-4. It features a different soundstage presentation than the LCD-X or LCD-4 to help simulate a room’s sound. Made right here in our Southern California facility to our exacting standards.
