The JAM Plus wireless Bluetooth speaker is the only JAM speaker that lets you pair two for true stereo sound. The JAM Plus speaker offers you high-quality, high volume sound that will have your friends wondering how a speaker so little produces sound so big. It pairs easily with your Bluetooth devices, streams music up to 30 feet away, and even offers an integrated speakerphone that instantly transfers from music to conversation. Best of all, you can double the sound output and get true stereo sound by pairing two JAM Plus wireless speakers to your device – and play them both for up to six hours between charges.
