Q1: What is the battery life of the earphones and the charging case?
A: The earphones offer
6–8 hours of single-charge playback at medium volume. With the charging case, the
total battery life reaches 24–32 hours.
Actual duration varies by volume and usage (music vs. calls): higher volume and longer call time slightly reduce battery life.
For better battery performance and hearing health, it is recommended to keep the volume below 60% and avoid prolonged high-volume use.
Q2: How to charge the earphones and charging case? What are the charging indicators?
A: Charging steps:
- Place the earphones into the charging case, ensure the charging contacts are properly aligned, and close the lid — the earphones will charge automatically.
The charging case supports Type‑C wired charging. Connect the included data cable to the case and a charger to charge both the case and earphones simultaneously.
Q3: What if the earphones do not charge or cannot fully charge in the case?
A: Troubleshooting steps:
- Check if the charging case has power. If the case is low on power, it will stop charging the earphones — charge the case first.
- Check for dirt or oxidation on the charging contacts of the earphones and case. Gently clean the contacts with a clean soft cloth or a cotton swab lightly dampened with medical alcohol, then reinsert the earphones.
- If any charging contact is sunken, apply 2–4 drops of alcohol, press up and down with a cotton swab about 20 times (1 per second), soak for 30 seconds, then wipe clean. Check if the contact springs back; repeat if needed.
- Use only the original data cable and charger — non-original accessories may cause abnormal charging.
If the above steps do not work, try restoring the earphones to factory settings, or contact after-sales support for inspection.
Q4: What if the earphones stay connected to the device after closing the charging case?
A: Usually caused by low case power or dirty contacts:
- Check the charging case battery. Charge the case for 10 minutes, then close the lid and test again.
- Clean the charging contacts on the earphones and case to ensure good contact. When properly detected, the earphones will disconnect after the lid is closed.
- If the problem persists, restore the earphones to factory settings and pair again.
