Do not charge the battery if the terminal of the USB charging cable is bent, loose, or damaged. Doing so may cause
heat generation, smoke emission, fire or electric shock.

charges, the life of the rechargeable battery may be reduced, or the rechargeable battery may no longer be able to be
charged.
Do not charge the product if water or foreign matter is inside the battery jack or USB charging cable. Doing so may
cause corrosion, heat generation, smoke, fire, or other malfunction or electric shock in the battery jack or USB

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.
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.
Earpads are consumable parts. The earpads deteriorate over time due to use or storage. Contact your local
Audio-Technica dealer for earpads replacement or other repairs.
