1.3 Wearing the Earphones

The OpenDots 2 E320 earphones feature an open-ear design and do not need to be inserted into the ear canal. They automatically detect wearing status and do not distinguish between left and right ears.

Earphone Components:

Wearing Instructions:

1. Hold the dynamic arc with your thumb and forefinger, then lift the earphone.
2. Gently push the earphone along the outer edge of your ear. The Sound Ball should rest against the concha, and the Energy Cabin should be positioned behind the ear.
3. Adjust the earphone to a comfortable wearing position. It is recommended to slightly tilt the dynamic arc downwards (angle between 0° and 30°).

Avoid Common Wearing Mistakes:

• The Sound Ball should be in front of the ear canal, not inserted into it.
• Do not excessively raise or lower the dynamic arc when wearing.
• Avoid pulling, twisting, or bending the dynamic arc forcefully.
