I bought the envent livefree 325 Bluetooth speaker 2 month ago. At first the the sound quality of this device at high volume sound is not clear, and it is takes a long time to full charge. And the bettary backup is very poor, and it is not connect easily with mobile Bluetooth, it ’s Bluetooth range is very limited, it is connect with wire also but it is loose attached with wire’ s pin. And the design is not more attractive but at average volume it works good. And last the price is very high according to it’s feature. So I think my review will be usefull for you. Thank u.
