Oh yes, Bluetooth and hearing aids can be very strange companions. My husband has a different brand, but sometimes it will spontaneously pair with his phone, then the phone starts doing strange things. It can usually be "cured" by turning off both hearing aid and phone and then restarting them. This has happened to us with other electronic pairings as well, not just the hearing aids. Still an imperfect technology because the technology is trying to make so many, varied devices talk to each other.
