The LCD-X is a very efficient headphone that extracts the maximum power out of low-powered amplifiers and portable devices. It’s the most neutral of the LCD Collection and favored by recording engineers and musicians alike for its fast, dynamic and accurate playback. Our proprietary technology eliminates the breakup modes found in other designs improving focus and clarity. Patent-pending Fazor elements guide and manage the flow of sound for improved frequency extension and a more enveloping soundstage. The X and XC are sensitive enough to be driven directly by portable players like iPods, iPhones, and the better smartphones but an external amplifier produces better results.
