Cautions about charging: How to protect headphones and earbuds from malfunction or damage

Make sure everything is clean and dry

Failure to follow these instructions may lead to malfunction and/or damage to the headphones or earbuds. To avoid any damage or malfunction, always carefully inspect for the following before charging:

• Ensure there is no water, moisture, or dirt on or around the headphones, earbuds, charging case, charging port, or the surrounding area.
  If water, moisture, or dirt is found, remove it with a soft dry cloth and let it completely dry at room temperature before charging.
• Make sure the USB cable is not damaged, deformed, wet, or dirty.
  If moisture or dirt is found, clean or dry the USB cable before using it. If the cable is damaged or deformed, use an undamaged USB cable.

Avoid situations that may expose the headphones or earbuds to water or moisture

If the headphones, earbuds, charging case, or charging port are used near water sources or moisture, they may become wet or develop condensation on or around them. If you have a Truly Wireless earbud model, always keep the charging case lid closed.

• Do not use or store the headphones or earbuds near water sources (e.g. bathroom or kitchen sink, bathtub, shower, pool, etc.).
  If you use the device near water, moisture may develop and cause damage or malfunction to the device.
  
• Do not use the headphones or earbuds in the rain, or carry them in your pocket, even if you are under an umbrella.
  Using a device in the rain may cause damage or malfunction to the device during charging.
