1. Important Safety Instructions

Hearing Protection

❗ Danger

To avoid hearing damage, limit the time you use the headphones at high volume and set the volume to a safe level. The higher the volume, the shorter the listening time.

Always follow these instructions when using headphones:

• Use headphones to listen at a reasonable volume, and for a reasonable duration.
• Be careful not to continuously increase the volume as your hearing adjusts.
• Do not increase the volume so much that you cannot hear what is happening around you.
• Be cautious or temporarily stop using the device in potentially dangerous situations.
• Excessive sound pressure from headphones can cause hearing loss.
• Using headphones in both ears while driving is not recommended and may be illegal in some areas.
• For your safety, avoid being distracted by music or phone calls while in traffic or in other potentially dangerous environments.

Charge the Battery

Charging Case

Connect one end of the USB cable to the charging case and the other end to a power source.

Note:

• Before first use, place the earbuds in the charging case and charge the battery for 2 hours for optimal capacity and battery life.
• Use only the original Type-C USB charging cable to avoid potential damage.
• Finish your call before charging the earbuds. When placed in the charging case, the earbuds will also turn off.
• If the earbuds with microphone are not used for a long time, the rechargeable battery will start to lose its charge. To avoid this loss, fully charge the battery at least once every three months.

Tip: The charging case serves as a portable backup battery for charging the earbuds. When the charging case is fully charged, it supports 3 full earbud charges.

Earbuds

Remove the earbuds and peel off the insulating stickers.
