Amplified speaker with rechargeable battery. Small and compact but complete with all the functions required by young people who want to listen to music in complete freedom. It includes a Bluetooth module to receive music directly from your phone. It can read MP3 files from micro SD cards and it also comes with a 3.5mm auxiliary input. The battery can be recharged directly from any USB socket (cable included) and guarantees hours of autonomy. The solid structure and very small weight make it the ideal player for any age. The woofer lights up, producing a nice effect. The package includes a microphone that can be used for karaoke (with echo effect) or simply to amplify your voice. Grid colour: blue.
