Ans: If you are experiencing this issue, then try adjusting the volume on your iPad or iPhone (or) try with another pair of headphones. In case, if the second pair works, then you have to contact the manufacturer of your initial headphones and go for a replacement. In case, if the second pair also won’t work, then contact Apple Support for further assistance. Alternatively, ensure to check the built-in microphone of the headphones for blockages (if any, including lint, debris, or pack). Try the second pair and if it works, then contact your initial pair manufacturer. And in case the second pair won’t work, then contact Apple Support.
