A:Answer The Sony SRS-XB2(3) speakers have the ability to be "paired" together with each other (2 speakers required) utilizing the built-in "Speaker Add Function" that allows 2 of these speakers to communicate with each other using a discreet Bluetooth signal generated by the speaker itself. The speakers can then be set to separate a stereo signal into right and left channels for "True" stereo sound. (NOTE: This only works when you have a device (tablet, smart phone, Bluetooth enabled MP3 player) that is sending the initial speaker a Bluetooth signal that is in stereo to begin with). ... The SRSX2 is just a "stand-alone" portable, battery-powered Bluetooth speaker that cannot be paired with any other speakers. It cannot supply a truly separated right and left channel stereo sound experience, even though it is playing two channels of stereo sound out of two separate speakers, these speakers are still contained within one container/case, thus the right and left channel stereo sound separation is permanently "muddled" within the speakers case before it ever reaches your ears.
