Keeping your headphones clean

When the headset exterior is dirty, wipe it clean with a soft dry cloth. If the headset is particularly dirty, soak a cloth in diluted neutral detergent, and wring it well before using it to clean the headset. Do not use solvents such as thinner, benzene, or alcohol, as they may damage the finish on the surface of the headset or cause other damages.
