Experience the unrivaled audio quality of our Flagship LCD-4 without the need for an amplifier. No other headphone in the world features such a robust and musically engaging sound signature in such an efficient package. With an impedance rating of just 15 ohms, the LCD-4z can be driven straight from the Aux port of your favorite listening device. If that’s not enough, our cast-magnesium housing yields a design that is lighter-weight than our standard LCD-4, making the 4z well-suited for extended listening sessions.
