A:AnswerTwo of the original Wonderboom speakers can be paired for louder, further audio, but they will not play in stereo. The Wonderboom 2 speakers however will play in stereo when paired together to each other. The initial speaker paired to your phone will be the right channel, the second speaker will be the left channel.
