The Audeze LCD-XC headphones might look like regular headphones. An oversized, overstuffed "regular" headphone, perhaps. It's unlikely you'll see anyone on the subway with these, or pulling a pair out after wheels-up on a cross-country flight. Except... you could. The LCD-XC's are Audeze's first closed-back headphones, and if you don't know what that means, don't worry, I'll explain.
