What phones are the Duo and Nano compatible with?

The Duo and Nano support the following phones running Apple iOS 11 and above, or Android 6 and above:

• iPhone 5, 6, 7, 8, X, 11, 12, 13 (including variants like the S, Plus, Max, and Pro).
  
  Note: The Duo plugs directly into your iPhone's lightning port. But if you're using a Nano you'll need the official Apple Lightning to 3.5mm headphone jack adapter for iPhone 7 and newer! If your phone didn't come with one, you can buy them from Apple's website here, or your local Apple store brand new for $9. Note, 3rd party adapters from Amazon usually don't work! 
  
  Similarly, if your Android phone only has a USB-C port and no headphone jack, you can use Google's official headphone jack to USB-C adapter found online here for $12 brand new. Note, 3rd party adapters from Amazon usually don't work
