Precautions

Because the headphones are of a high density enclosure, forcing them against your ears may result in eardrum damage. Avoid using the headphones where they are liable to be struck by people or other objects, such as a ball, etc. Pressing the headphones against your ears may produce a diaphragm click sound. This is not a malfunction. Listening with headphones at high volume may affect your hearing. For traffic safety, do not use while driving or cycling. The earbuds may deteriorate due to long-term storage or use. Install the earbuds firmly onto the headphones. If an earbud accidentally detaches and is left in your ear, it may cause injury.
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. The effect can be minimized by wearing clothes made from natural materials. EP-EX10A is available (sold separately) as optional replacement earbuds. EP-EX10A offers 4 types of the earbuds: SS, S, M and L.
