Whether in the workshop or on the construction site, you can always enjoy the sound of TOPROCK. You can listen to your favorite track on your smartphone via the Bluetooth® interface with outstanding quality wherever you are. Tools and accessories can be stored inside the TOPROCK and are easy to transport. TOPROCK is equipped with Bluetooth® 5 with TWS (true wireless stereo). When two TOPROCK speakers are connected, these act as the right-hand and the left-hand speaker, allowing for a stereo sound which fills the room. The integrated battery allows for an operating time of up to ten hours at a medium volume. It is then easy to charge the Bluetooth® speaker with the supplied power cable. External devices, such as smartphones, are easy to charge via the integrated USB interface. The four high-quality neodymium speakers let you rock out with a total power of 20 watts. Two bass reflex systems provide a rich, voluminous sound. The illuminated buttons are discreetly integrated in the Systainer lid and are intuitive to operate: On and off, volume up and down, connect to Bluetooth®.
