Safety First
Vibration speaker designed to deliver music and handsfree calling
through a bicycle, ski, construction or other safety helmet.
The helmet is used to conduct the sound. Simply connect to any
smartphone and you can listen to your music and take handsfree
(group) phonecalls. Because you do not plug it into your ear, you
can still hear your surroundings. Good branding area and adapts
easily to many different styles.
