Stereo pairing only works between 2 speakers at most and you would need to pair two identical speakers at the same time to create a stereo sound that distinguishes the L (left) and the R (right) channel separately.
 

To pair two Soundcore Motion Boom speakers together, follow the steps listed below.

1. Turn on both Motion Boom speakers. The indicator on both speakers will be flashing blue.

2. Short press the TWS button on both speakers. The button on both speakers will be flashing white.

3. After successful pairing, the TWS button on both speakers will become solid white. 

The secondary speaker's Bluetooth button indicator will turn off.

The primary speaker's Bluetooth button indicator will show flashing blue.

4. Use the primary speaker to connect with other devices.
 

Note: Avoid having any electronic devices between both speakers, and make sure the distance between the two speakers is not greater than 5 meters.
