Sinus Blue tooth headphones and speakers

Why choose between headphones and portable speakers when you can see both at once? This is what the German designer Tino Klaehn with its concept called Sinus.  Sinus is a dual-function concept as often seen in recent times. Posing as a headset design, it can turn into speakers at any time. The aesthetic is at the forefront with this ultra-modern helmet declined in several versions for different reasons.

 The helmet has two comfortable headphones broadcasting a pure sound and quality, insulating the user in his musical universe. To listen to music as a group, simply rotate the speakers at the two hinges. The user can be relieved cables as sinus has a Bluetooth connection. The concept also has a Sinus USB port and an internal memory unknown.
