Maintenance
Cleaning Your Earbuds
To maintain optimal sound quality and hygiene, regularly clean your earbuds. Use a soft, dry, lint-free cloth to wipe the earbuds and charging case. For ear tips, you can gently remove them and clean with a mild soap solution, then rinse and dry thoroughly before reattaching.
IP7 Waterproof Rating
The Mysic J5 earbuds and charging case feature an IP7 waterproof and sweatproof design. This means they are protected against the effects of temporary immersion in water (up to 1 meter for 30 minutes). They are suitable for workouts, running, and other activities where they might be exposed to sweat or light rain. Note: While waterproof, avoid prolonged submersion in water and do not use them for swimming or showering.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing with device. | Bluetooth is off on device; earbuds are out of charge; earbuds are already paired to another device. | Ensure Bluetooth is enabled. Place earbuds back in case, close, then reopen to reset. Forget "J5" on your device's Bluetooth list and re-pair. Ensure earbuds are charged. |
| Only one earbud working. | One earbud is out of charge; earbuds are not properly connected to each other. | Place both earbuds in the charging case and ensure they are charging. Take them out together to allow them to connect to each other before connecting to your device. |
| Low volume or poor sound quality. | Ear tips are not sealed properly; earbud speakers are dirty; device volume is low. | Try different sized ear tips for a better seal. Clean the earbud speakers. Increase volume on both your device and the earbuds. |
| Charging case not charging. | Charging cable or adapter issue; charging port is dirty. | Try a different Type-C cable and USB adapter. Clean the charging port gently with a dry cotton swab. |
