I just bought this Costco FP-10 bundle. I'm happy enough with the piano but disappointed with the connectivity. The included headphones have a 3.5mm plug while the piano jack is 2.5mm so I'll need an adapter. The USB is type B which is pretty old style. Most importantly, the Bluetooth is not the general audio connection that I expected would allow me to listen via my phone or my Compilot device that links to my hearing aids. I don't understand how Bluetooth can be limited to an app but apparently they tie it to Roland Piano Partner 2 which seems to be midi oriented.
If anyone has tips on how to make the Bluetooth work as audio I would greatly appreciate it.
