Hello AKCat, thank you for your question. There are controls on both the left and right sides of the Jabra Elite Active 45e. On the left side, you have the button to access your voice assistant and to mute your microphone while on phone calls. On the right side, you will see the volume up and down buttons and the multi-function button. This button allows you to turn the headphones on and off, pause and unpause music, answer and end calls, and put your headphones into pairing mode.
