5. My earbuds are not pairing to each other. How can I manually pair them?

The earbuds should pair when the charging case lid is opened. In the unlikely event of this not occurring, place both earbuds back in the charging case and long press both earbud multifunction keys simultaneously.

6. Can the ear tips affect the ANC and sound performance?

Yes. It is important to choose the ear tip that creates the best seal in your ear whilst being comfortable. A poor seal will allow external sound to leak in and reduce the accuracy of ANC, as well as reduce bass performance.

9. Will Mu3 auto power off? How do I wake the earbuds back up?

Mu3 earbuds will turn off after 10 minutes without a Bluetooth connection to conserve battery. To wake them back up, place the earbuds back in the case and close the lid. The earbuds will power back on when the lid is opened again.

The charging case will enter sleep mode if the lid is open for more than 10 mins. Please close the lid and re-open the lid to wake it up.
