Troubleshooting
Callers say I sound unclear or too far away
Adjust the position of your microphone to approximately 2.5cm from the corner of your
mouth, level with your chin. Here the microphone will pick up the sound waves from your
speech but not the air moving from your nose and mouth.
My voice echoes or I sound like I am in a tunnel
