Before You Start: If one or both earbuds are not charging, the issue may be caused by a loose USB cable, poor contact with the charging pins, or an insufficient power supply.
Check the Earbud LEDs:
Solid RED – Charging
LED OFF – Fully charged
Charging Time: Approximately 2 hours.
Step 1 – Check the Charging Base & Power Supply
- Connect the charging base to a 5V / 1A USB power source.
- Make sure the USB cable is securely connected.
- Place both earbuds in the charging base and check whether their LEDs turn Solid RED.
Charging Normally? Leave the earbuds charging for approximately 2 hours.
Note: Avoid using 9V or 12V fast chargers.
Place both earbuds in the charging base and check for the red charging lights.
Step 2 – Check the Earbuds & Charging Contacts
- Remove both earbuds from the charging base.
- Place the LEFT (L) earbud in the L slot and the RIGHT (R) earbud in the R slot.
- Gently press each earbud down to ensure it touches the charging pins.
- If an LED does not turn Solid RED, clean the metal charging contacts on the earbuds and inside the base with a clean, dry cloth or cotton swab.
- Place both earbuds back in the charging base and check the LEDs again.
Step 3 – Check the Charging Pins & Try Another Power Source
- Check the small charging pins inside the base. Make sure they are not stuck, bent, or dirty.
- Try a new compatible USB charging cable.
- Connect the charging base to another 5V / 1A USB charger or USB port.
- Place both earbuds back in the base and check whether the LEDs turn Solid RED.
Battery Completely Drained? Leave both earbuds charging for at least 10–15 minutes before trying to turn them ON.
Still Not Charging?
If one or both earbuds still won't charge, please tell us which earbud is affected and whether its LED turns Solid RED. If possible, include a photo or short video showing the charging issue.
