Cleaning Your Headphones
To keep your headphones clean, periodically wipe with a dry cloth.
Note on Static Electricity
In particularly dry air conditions, mild tingling may be felt on your ears. This is a result of static
electricity accumulated in the body, and not a malfunction of the headphones. Wearing clothes
made from natural materials can minimize the effect.
