What do you need to operate a cellphone hands-free?

• A. Bluetooth/Hands-Free
• B. Voice Command Only
• C. In-Car Telephone Mount
• D. External Speakerphone

Answer: (A)

To operate a cellphone hands-free, you need a hands-free connection that lets the audio go to your ears and your voice go to the phone without holding it. Bluetooth provides that wireless link to a car system or headset, so you can hear through the car speakers and speak into a microphone while using voice commands to dial or answer calls. A voice command feature alone doesn’t supply the actual audio pathway; a car mount by itself doesn’t create a hands-free audio connection, and an external speakerphone might work only if it’s paired or integrated with the phone’s hands-free system. So the Bluetooth/Hands-Free setup is the reliable method that enables true hands-free operation.
