Setup and First Use
1. Charging the Earbuds and Case
Before first use, ensure both the earbuds and the charging case are fully charged. Connect the provided USB charging cable to the charging case and a power source. The indicator lights on the case will show the charging status. The earbuds will charge automatically when placed inside the case.

2. One-Step Pairing
The Y50 TWS headphones are designed for effortless pairing:
- Open the charging case. The earbuds will automatically power on.
- Take both earbuds out of the charging case. They will automatically enter pairing mode and connect to each other.
- On your device (smartphone, tablet, etc.), go to Bluetooth settings and search for "Y50" (or similar name).
- Select "Y50" to connect. Once connected, you will hear a confirmation tone, and the earbuds will be ready for use.
Once paired, the earbuds will automatically connect to the last paired device when taken out of the case.

Operating Instructions
The Y50 TWS headphones feature intuitive touch controls for easy management of calls and music playback.

Music Playback

Refer to the quick start guide included in your package for precise instructions if not covered here.
Maintenance and Care
- Cleaning: Use a soft, dry, lint-free cloth to clean the earbuds and charging case. Do not use harsh chemicals or abrasive materials.

- Charging: Always use the provided charging cable. Avoid using damaged cables or chargers.
- Storage: When not in use, store the earbuds in their charging case to protect them and keep them charged. Store in a cool, dry place away from extreme temperatures.
