These are the Bluetooth headset similar to the functions of bone-conduction speakers. The microphone picks up from the vibration from your larynx and it will turn them in to sounds. We have seen plenty of Bluetooth headsets with different feature but the only feature in Roadrunner headset

is that it fits around your neck. You will get a good music experience but it is hard to wear Bluetooth around your neck. The Roadrunner neckset costs $40 and you will get a newer experience of Bluetooth neckset.
