Get into the habit of regularly cleaning the product to ensure that it will last for a long time. Do not use alcohol, paint
thinners, or other solvents for cleaning purposes.
• Wipe any dirt off the headphones and charging case with a dry cloth.
• Immediately wipe off any moisture (such as sweat) that has splashed onto the
charging case battery jack, the charging terminals, and operation controls (such
as buttons on the headphones). Failure to do so may result in a malfunction due
to corrosion.
• Natural oils from the skin are particularly likely to build up on the eartip
attachment parts (see figure at right). If these areas are not cleaned, the eartips
can become detached. Clean them regularly. Do not touch the areas where
sound is produced as they are delicate. Doing so may result in malfunction.
• If the USB charging cable is dirty, wipe the cable with a dry cloth immediately
after use. Failure to clean the cable may cause it to deteriorate and harden over
time, resulting in malfunction.
• If the USB terminal of the charging cable is dirty, wipe it off with a dry cloth.
• Clean the eartips by removing them from the headphones and manually
cleaning them with a diluted mild detergent. After cleaning, wipe dry before using again.
• If the product will not be used for an extended period of time, store it in a well-ventilated place free from high
temperatures and humidity.
