Compact and portable cube-shaped wireless Bluetooth 2.1 speaker that features a built-in battery and robust, splash-proof design with side panels made of rubber and reinforced edges, allowing user to use it anywhere and at any time. Its operation is simple and straightforward: If the device is switched on, it can be directly coupled with a Bluetooth-enabled smartphone or tablet. The control panel on the speaker allows controlling the music playing on the radio (play, pause, track forward, track back), and a switchable sound-enhancing effect (bass boost) provides a significant amplification of lower frequencies to give bass-heavy music a boost. In addition, with its built-in microphone it allows managing the phone calls. If the device is coupled with user's smartphone, incoming calls can be easily accepted or rejected with the push of a button. The speaker also features a redial function. Other features include Bluetooth, On/Off and battery status LED lights, an On/Off switch and a miniUSB port for charging. Dimensions: 130 x 130 x 125 mm. Weight: 0.7 kg.
