Overview

What’s included

Choosing the right ear tips:
The perceived sound quality and bass performance of the earbuds depends greatly on the correct fit of the earbuds in the ear. Please test which ear tip size gives you the best sound quality and the best wearing comfort.

How to wear

   Insert the earbuds into your ears. Adjust the angle of the left earbud to roughly match the diagram on the left. Do the same with the right earbud.

2. Secure fit
   You can transform the earbuds to the Secure Fit version by attaching the wing tips onto the earbuds. Adjust the angle of the left earbud and wing tip to roughly match the diagram on the left. Do the same with the right earbud.

3. Sport fit
   You can transform the earbuds to the Sport Fit version by attaching the sport hooks onto the earbuds. Adjust the angle of the left earbud and sport hook to roughly match the diagram on the left. Do the same with the right earbud.

Charge the charging case to start

The earbuds come with a charging case that contains a built-in high-capacity rechargeable battery to recharge the earbuds.
For first-time use, toggle the on-off switch on the charging case to the “ON” position to activate the case.

To charge the charging case, use the provided USB-C Cable and connect the USB-C connector to the DC-IN port on the charging case and the other side (Standard USB-A) to a USB Power Source such as a 5V USB adaptor (not included). The power level indicators will blink when charging.

Charging the earbuds

Insert the left & right earbuds into the charging case respectively to charge. Check if a red light appears on each earbud to ensure the earbuds are charging. The charging case also has two earbud charging indicators to check the charging status of the earbuds located on the front side of the charging case. Each charging indicator lights up when charging and turns off when the respective earbud is fully charged.

NOTE 1: The left charging indicator indicates the charging state of the left earbud and the right charging indicator indicates the charging state of the right earbuds.
NOTE 2: Wing tips with wrong angle on the earbuds may prevent the earbuds from fitting well into the charging case. Adjust the angle of the wing tips if necessary.

How to pair (Dual/Stereo earbuds mode)

• Take out the earbuds from the charging case and fit the earbuds to your ears. The distance between the earbuds to the device (also each bud to the other) for pairing must not exceed 2m.
• The two earbuds will power on with a short “beep” sound and pair with each other automatically.
• You will hear the voice prompt announce “Pairing”.

NOTE: The connection between the earbuds may cut out temporarily on occasion. This is normal for wireless earbuds. However, if the connection cuts out intermittently, then it may be caused by radio interference (e.g. near wifi router) or an obstacle blocking the signals. Try moving to another area/location for better connection.
