Eargo devices and telephones
Sometimes people experience feedback 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. If this happens, move the phone back from your ear a bit.
[Eargo’s] SP1 (Sound Profile 1) is designed for the phone, so if you ever experience feedback while on the phone, be sure to try this setting. Some people also have success using speaker phones.
