Cleaning
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.
Use a dry cloth to clean the headphones and the in-line controller.
Wipe away any perspiration or dirt from 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.
Wipe the cable plug with a dry cloth if dirty. Failure to clean the plug may cause sound skipping or noise.
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.
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.
Earpads are consumable parts. The earpads deteriorate over time due to use or storage. Contact your local
Audio-Technica dealer for earpad replacement or other repairs.
