Stereo pairing only works with a maximum of 2 speakers, and you would need to pair two identical speakers at the same time. 

（Note: Please ensure that your two X500 speakers are on the same firmware version. If the firmware versions differ, it may result in unsuccessful TWS pairing. The firmware version can be checked by connecting to the soundcore App）

There are two methods to pair two soundcore Motion X500 speakers together:

Method 1:

1. Turn the two speakers on.

2. Speaker 1 and Speaker 2: Long press the power button to start both speakers.

3. Speaker 1: Hold the Bluetooth button until the button light flashes white.

4. Speaker 2: Hold the Bluetooth button until the button light flashes white.

5. Wait for a few seconds, and you will hear a sound when the two speakers have paired successfully.

6. The master speaker is the one with the blue light.

7. Use the master speaker to pair with your device.

Method 2:

1. Long press the power button to start both speakers.

2. Connect either speaker to your Bluetooth device.

3. On both speakers, press and hold the Bluetooth button for at least 2 seconds to enter TWS pairing mode.

4. Wait for a few seconds, and you will hear a sound when the two speakers have paired successfully.
