How to Adjust the Volume on an iPhone Headset Microphone
By Avery Martin
The headsets included with the iPhone 5 come equipped with three buttons located on the iPhone headset's microphone, also known as a control capsule. The control capsule provides a way to change the volume of audio by using the top and botton buttons. Additionally, you can stop and start playback using the middle button, or select the next song or previous song when using the Music app or another supported app. The control capsule also provides a way to answer and end calls by pressing the center button.
Tap the Settings app, select "Music" and select the "Volume Limit" option. Slide the Max Volume slider to the right to increase the maximum volume.
Press the "+" button on the side of your iPhone to increase the volume or the "-" button to lower the volume with your headphones plugged in.
Press the "+" button on the built-in headphone remote to raise the volume or the "-" button to lower the volume when listening to audio with your headphones.
Adjust the position of the headset microphone and speak close to the microphone to increase the volume of your voice. Hold it further away from your body to decrease the volume. Don't hold the microphone too close since it could cause distortion.
Clean the microphone by shooting compressed air into the microphone hole on the control capsule. Use short bursts of air to remove any lint that may impede the microphone's capability to capture sound.
