Cleaning
Get into the habit of regularly cleaning your headphones to ensure that they
will last for a long time. Do not use alcohol, paint thinners or other solvents
for cleaning purposes.
• Use a dry cloth to clean the headphones and the in-line controller.
• After using the included cable, clean it with a dry cloth if sweat or dirt is
present. Failure to clean the cable may cause it to deteriorate and harden
over time, resulting in malfunction.
• Wipe your plugs on included cables with a dry cloth if dirty. Using the
plug without cleaning it can cause sound skipping or distortion.
• To clean the earpads and headband, wipe with a dry cloth. Earpads and
headband may fade if sweat or water dries on them. If the earpads and
headband get wet, we recommend wiping them with a dry cloth and
allowing them to dry in the shade.
• For long-time storage, keep the product in a well-ventilated place free
from high temperatures and humidity.
• Earpads will deteriorate over time due to use and storage. Replace when
necessary. For information about replacing earpads or other parts, or for
information about other serviceable parts, contact your Audio-Technica
dealer.
