I'm always wearing my sunglasses and my ear buds. Not anymore. These bluetooth sunglasses have the speakers and microphone built in. You can listen to music or take a call while you're on your commute or walking to dog. Your ears are not obstructed so you can still hear a car or person near you. The sound is directed eight at your ears so no one else can hear. They don't even look half bad, with various styles. The newer versions have longer battery life and better sound, but the original Altos are a classics style and less expensive.
