Why does the QCY app ask for location access?

If you prefer not to share your location, close the app and try pairing again.

My headphones' battery runs out too quickly. What can I do?

What's the difference between connecting the H3 Pro via AUX cable and using Bluetooth?
When using the AUX cable, you can still enjoy ANC, but the headphones will turn off, and the Bluetooth chip will stop functioning. The main differences are:
- The app cannot connect, and EQ settings (both presets and custom) are disabled.
- AUX connection does not consume battery power, as the headphones are powered through the cable.
- There is no delay when using the AUX cable.
How should I care for my earphone?
1. Use your earphone regularly to avoid battery over-discharge. Aim to use them at least once a month.
2. Charge the earphone after each use, and don't wait until they drop below 20% to charge.
