Heavy music (especially rock) makes its way to the bones, its vibrations shake every cell of the body. It became easy to experience such feelings, just put on a Baserock backpack. The effect is achieved with the help of two vibration devices with a power of 15 W, integrated into the product design, which transform the sound into vibration acting on the back of the carrier. Moreover, the intensity of the vibrations can be adjusted using a special device on the shoulder strap. Such a backpack at a rock concert will catch an acoustic signal through a microphone even from a distance, although it is mainly intended for connecting a smartphone and using its music library. The battery of the 2000 mAh device is designed for 8 hours of trouble-free operation, so even enough to listen to the biggest rock concert. But don’t think that the Baserock backpack is just a mobile speaker behind. It also fulfills its direct functions: you can carry things in it, scatter little things in pockets with fasteners, and a two-liter tank is built in for water or other liquid. And what for a lover of hard rock some $ 199 if he can feel his favorite music anywhere with his whole body!
