  • 1. Asynchronous earbuds’ battery level

Our true wireless earbuds are based on an asymmetric control model. This is a normal communication structure for earbuds and allows for each earbud to rely on the other dynamically in order to extend battery life. However, this can lead to asynchronous battery levels between earbuds.




  • 2. Device still connected

Your device might be still connected to Gemini, even though the earbuds are back in their charging case.



If this is occurring, please do the following: when putting your earbuds inside the charging case, please wait 3 seconds before closing the lid to allow Gemini to disconnect from your device.

Additionally, you can disable bluetooth from your source device to ensure the connection is severed.
