Since the App will pair with the BT headset, need to allow recording as an alternative to the long-range coms via cell/wifi. For non-Sena camera users (i.e. GoPro or others) this could allow recording of audio tracks for syncing with video in editing, using the memory on a smartphone to record mp3 files. I am currently using the 20S EVO model but this could potentially work for any of the BT headsets that the app already pairs with.
