Great Question, The QC20i headset will only work with Apple products so while you'll be able to use them to listen to music on your Blackberry the microphone and controls will not function as expected. The QC20 headset has been optimized for use with the Samsung Galaxy products and will have limited functionality with the Apple or Blackberry devices.
We suggest choosing the model that is suitable for use with your iPhone and test it to see what functions work differently with your Blackberry.
