3. Audio Quality and Microphone
Experience superior Hi-Fi Stereo Sound with 13mm dynamic drivers that deliver real and dynamic audio. The built-in microphone provides clear sound quality for calls and voice assistant interactions.
Due to the open-ear clip-on design, the intelligent noise cancellation feature is not as pronounced as with in-ear earbuds. However, the overall sound quality remains excellent, allowing you to enjoy clear music and calls even in moderately noisy environments while maintaining awareness of your surroundings.

Maintenance
Water Resistance
The aigo Open Ear Earbuds are highly waterproof with an IPX4 rating. This means they are resistant to splashing water from any direction, making them suitable for use during workouts, running, or in light rain without worry. Avoid submerging the earbuds in water.
To maintain optimal performance, regularly clean the earbuds with a soft, dry cloth. Ensure the charging contacts on both the earbuds and the case are free from dust and debris.

If you encounter any issues with your aigo Open Ear Earbuds, please refer to the following common solutions:
- Earbuds not pairing or connecting:
