The Bluetooth controls allow adjustments to the hearing aid settings. But, there are zero options to control phone calls and streaming. It’s just on. Every notification on your phone plays in the hearing aid. There is a constant “connected” or “disconnected” played as the connection picks up and drops between the phone and hearing aid. The hearing aids work fine, but the Bluetooth streaming and app are not well thought out or developed. Answering phone calls hands free would be great, but not if it comes with sounds for every phone notification or announcements on connections. Every notification also cuts off the hearing aid’s microphone, so your hearing is interrupted just before, during, and just after a notification or connection announcement.
