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.
Do not put weight or pressure on the headphones as it may cause
the headphones to deform during long storage.
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.
Do not leave the stereo headphones in a location subject to direct
sunlight, heat or moisture.
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.
