Good morning. I appreciate your inquiry regarding your LG VX8700 playing music through a Bluetooth Headset. My name is Laura, and I am happy to assist you today.
You are correct, your LG VX8700 is Bluetooth capable. If you are wanting to hear music through the headset, you will need to purchase a Bluetooth Headset with Stereo. Currently we have the Motorola Bluetooth Stereo Headphones for $99.99.
We offer several convenient purchase options, which I provided below:
