Thank you for your interest in the SoundLink Color Bluetooth Speaker II. You can play music simultaneously on two of these speakers. Please ensure that your iPod supports built-in Bluetooth. If you have an iPod Touch running iOS 9 or newer, you can pair the speakers using the Bose Connect app. Alternatively, the speakers can be paired manually using the steps here: https://bose.life/2pAbhMX.
