This speaker 2.0 stereo offers powerful sound and sound reproduction. Despite the space saving design, this device does not compromise on sound quality, producing a well-balanced speaker system with nearly distortion-free sound. Power is supplied via the USB chord, and the connection is via a 3.5 mm jack plug and therefore suitable for multiple devices such as a PC, notebook or MP3 player. In addition, the Bluetooth function enhances functionality by allowing you to play music without turning on the PC or notebook.
