With the Samsung Level Box Slim, you can listen to clear sound at home, in the park, or at the beach. This compact Bluetooth speaker has a waterproof design. You can put the device in the wet sand or at the poolside without any problems. The integrated battery guarantees up to 30 hours of wireless listening pleasure. Is your smartphone's battery nearly empty? You can connect it to the speaker with a micro USB cable. That way, the battery will be automatically charged. On the back of the speaker is a stand that you can easily fold in and out.
