4. Setup
4.1 Charging the Earphones and Case
Before initial use, ensure both the earphones and the charging case are fully charged. Connect the provided USB Type-C cable to the charging port on the case and a compatible USB power source.
- Charging Time: Approximately 1 hour for earphones.
- Battery Life: Earphones provide about 4.5 hours of playback on a single charge. The charging case extends total usage to up to 20 hours.
4.2 Wearing the Earphones
The ERAZER X15 Pro features an open-ear ear-hook design for comfort and hygiene, as it does not require insertion into the ear canal. The ear loop is soft and elastic, designed to fit securely without causing discomfort, even during extended wear.
- Identify the Left (L) and Right (R) earphones.
- Gently place the earphone over your ear, ensuring the ear hook wraps comfortably around the back of your ear.
- Adjust the earphone for a comfortable and secure fit. The sound should be directed towards your ear canal without blocking it entirely, allowing for ambient sound awareness.

4.3 Bluetooth Pairing
The earphones utilize Bluetooth 5.4 for a stable and fast connection, offering improved performance over previous versions.
- Open the charging case. The earphones will automatically power on and enter pairing mode (indicated by a flashing LED on the earphones).
- On your device (smartphone, tablet, computer), navigate to the Bluetooth settings.
- Search for "Lenovo ERAZER X15 Pro" or a similar name in the list of available devices.
- Select the earphones to connect. Once successfully connected, the LED indicator on the earphones will stop flashing.
The earphones support multi-point and multi-device compatibility, allowing for single ear or dual device connection. To clear all previous pairing information for a fresh connection, perform a deep clearing process (refer to troubleshooting if needed).
