I have a new iPhone SE. When I connect the Anker speaker to the iPhone using a Lightning / 3.5mm adaptor, the music and podcasts sounds great. But when I receive a phone call, the the audio does go to the connected Anker speaker but to the iPhone handset speaker.
I have tried to use the Bluetooth connection to the Anker for a phone calls but the microphone on the iPhone results in a very weak audio, much weaker than if I disconnect the bluetooth connection and just use the phone normally.
I was hoping that using the Anker could be helpful in making a conference call. Using Zoom and FaceTime the Anker works great.
For phone calls, something is not quite right with the Lightning/3.5 audio connection (no sound) and and Bluetooth connection (low mic pickup).
