The LCD-XC shares the same drivers and basic construction as the LCD-X, lending it a similar level of detail and transparency. Its closed-back design adds both isolation and a slight lift in bass response between 120-200Hz, making electric bass even more defined. If you want to hear Marcus Miller playing bass right next to you, the LCD-XC is your headphone. The Premium LCD-XC comes with both Balanced and Single-ended cables, the 1/4" to 1/8" stereo adapter, and our premium travel case. The Creator Pack comes with the Standard Single-ended cable and our new economy travel case.
