Sometimes people experience feedback, like whistling or buzzing, when talking on the phone and wearing a hearing device. This can happen when the phone is too close to the ear. The proximity can create a feedback loop between the phone's speaker and the device's microphone.
We recommend using speaker phone and the app-selectable 'Phone' program. You can also try holding the phone to your ear at an angle, backing the phone away from your ear an inch or two, or trying a larger-sized trumpet.
