Depending on the activated mode, the integrated lithium-ion battery allows for extensive music playback of up to 10 hours. Additionally, the wireless communication standard NFC enables a quick connection to supported devices without further setup. The precise separation of frequencies in a 3-way system ensures a rich and balanced sound character. The arrangement of the two 3-inch midrange drivers and 1-inch tweeter contributes to a wide stereo image, which particularly enhances music playback. With the Smart Link function, two Groove Blaster BT speakers can be wirelessly paired, doubling the overall volume and allowing for simultaneous placement of the speakers in multiple rooms.
