- Poor sound quality or frequent disconnections:
- Ensure the earbuds are properly seated in your ears and that you are using the correct size eartips for a good seal. Reduce the distance between the earbuds and your connected device, and ensure there are no major obstructions.
- Earbuds not charging:
