I am very satisfy to use this gadget. It’s Sound Quality is well define and high. It’s audio performance is powerful with solid bass response. It can charge mobile device like other charger as well as it is water resistance which make it special.It is very easy to carry anywhere.This gadget is an outdoor friendly portable Bluetooth speaker. It is too expensive but it’s quality is amazing if you are looking for a more compact speaker that can still deliver solid bass response, be really like Sony but I prefer this device in it’s price and size, and very good audio quality.
