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 Trance speakers together, follow the steps listed below.

1. Turn on both Soundcore Trance speakers and make sure they aren't paired with other devices.

2. Hold the Bluetooth button on both speakers for a few seconds simultaneously until both of them start flashing blue rapidly.

3. Wait for 5-8 seconds, you will hear a tone when the two speakers successfully pair together. One speaker will display a solid blue light and the other speaker will display a flashing blue light. You can connect your phone to the speaker that has the flashing blue light.
 

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