CleaningGet 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. 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. Immediately wipe off any moisture such as sweat from operating areas such as the buttons. Failure to do so may result in a malfunction due to corrosion. 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’s USB plug with a dry cloth if dirty. Wipe the cable with in-line mic and control’s plug with a dry cloth if dirty. Failure to clean the plug may cause sound skipping or noise.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.
