We do very strongly suggest using a headset with a microphone to eliminate echoing and feedback ruining the quality of your audio. However, if you are unable to find a headset with a microphone integrated, the tuition feature will still work for you - just make sure you, at the very least, use headphones to stop the audio from feeding back to the other person in the tuition feature. The audio does work without headphones too so don't worry if you cannot find yours. Just ensure that you don't have any background noise that might interfere with the learning experience.
