Yes, while your headphones are designed for stereo audio, they work great for phone calls. The mic is located next to the `power button` on your ‘inline remote’. See below for detailed call functionality.

• Accept a phone call -- Short press the Power Button
• Decline a phone call -- Press the Power Button for 1 second
• Mute/Unmute -- Press the Vol. - button for 1 second
• Redial -- Double press the Power Button when you’re in Standby Mode (Powered on and connected, but not playing music or on a phone call)
• Switch a call from your phone speaker to your FREEDOM headphones -- Short press the Vol. + button

NOTE: When you answer a call while connected to your FREEDOM headphones, the call audio will always come from your headphones whether you answer the call by pressing the power button on your headphones or the answer icon on your phone.
