A headset will let you talk hands-free without scrunching your cell phone between your ear and shoulder. Besides you’ll feel better, more productive and safer. Remember, using a cellular headset while driving is mandatory in some states, maybe even yours. The earbud fits comfortably inside the ear. The microphone is located on the cord. The headset allows you to talk freely. This gives you convenient, hands-free operation of your cell phone anywhere you are (features on/off button).
