Bluetooth connection is not stable during phone calls.
In this case we recommend placing your mobile phone in front of you or in your hand, but not in a tight pocket or otherwise pressed against your body, as the body blocks the Bluetooth signal.
While I’m on a call using the BeHear headset I periodically hear the voice prompt say “disconnected” and then “connected” (but the call doesn’t drop). How can I get it to stop?
This sometimes happens when two Bluetooth devices (e.g., your smartphone and a computer) are both connected to the BeHear headset. We recommend disconnecting the device which is not currently in use for the purposes of the call.
