I received this top Bluetooth speaker there a week, I have not needed to charge it while it runs daily ... autonomy is truly impressive (autonomy was part of my selection criteria before you buy). Also the sound quality is good for the small size of the speaker, bass correct. The Bluetooth connection with devices that are equipped works perfectly well (my mobile phone Wiko immediately detected). Moreover it is possible to connect the speaker directly to a device through the jack and cable plug (supplied), which allows not having to switch on the unit (as it works even in "off" mode ). The speaker is supplied with a cover, very convenient to carry ... I therefore strongly recommend this product to anyone who like me can not do without music, and looking a little Bluetooth speaker to take everywhere (rides, parties with friends around the fire etc ...), as well as those who want better sound than their laptop when they watch a movie. 10/10 again!
