- A: Ensure your device is within the 10m Bluetooth range and there are no significant obstacles between the headphones and your device. Check for interference from other wireless devices. Ensure earbuds are clean.
- Q: Headphones are not charging.
- A: Check if the charging cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean. Try a different charging cable or power adapter.
