How can I find my Headphones model name and serial number?

You can usually find the model name and seven-digit serial number either on the headband or inside the head-padding, as shown in the image below

Example: WH-1000XM6 (model code: YY2984)

• Make sure the headset is turned off and the USB cable is not connected.
• Remove the earpad from the right unit by pulling it straight off the housing. Avoid pulling it off at an angle.
  The serial number and safety marks, etc., are located on the lower right corner of the right unit.

• Attach the removed earpad to the right unit.
• Make sure to firmly insert the five tabs into the unit until you hear a click.

• Do not remove the earpad unless necessary.
• Before removing the earpad, make sure the headset is turned off and the USB cable is not connected.
• Do not remove the earpad in the presence of iron sand or other metal objects. Iron sand or other metal objects may adhere to the magnet inside the headset, causing the headset to malfunction.
• Any defects caused by failure to follow the above precautions are not covered by the product warranty.
