I have the Cochlear BAHA and it syncs with the iPhone. I'm not sure if the Oticon does though
The iPhone also has an app that allows you to control the processor ,, volume, program, troubleshooting,, and find a lost processor. I've really enjoyed the upgrade from the BAHA 4 that I had previously. This processor is so much clearer and better, I have the 5 power unit. It's wonderful!!
Good luck with your decision,,,,
