Yes, you can use the hearing aid fitting software namely (Connexx 9.12.3/RexFit9.12.1 for Rexton Newer/Current).Is there software available that will allow me to permanently adjust the R/L volume balance? And to add bass response to the Bluetooth setting?
No, it communicates using a different wireless protocol, namely BLE - Bluetooth Low Energy. And besides, it does not communicate directly with the hearing aid. You must use a hearing aid programming device, namely Noahlink Wireless 2.I'm assuming that if such software exists that it can communicate with the hearing aids via Bluetooth.
