4.3 Bluetooth Pairing

To connect your headphones to a device (smartphone, tablet, laptop):

1. Ensure the headphones are powered off.
2. Press and hold the power button for about 5-7 seconds until the indicator light flashes rapidly (often alternating blue and red), indicating pairing mode.
3. On your device, go to Bluetooth settings and turn Bluetooth on.
4. Search for available devices. Select "Erssimo H18 pro" (or similar name) from the list.
5. Once connected, the indicator light on the headphones will typically stop flashing and remain solid blue, or turn off, and an audible confirmation may be heard.

The headphones will automatically attempt to reconnect to the last paired device when powered on, if the device's Bluetooth is active and within range.
