I bought the spcinternet 8334S mp3 player before 3 month ago so I observed that in this device the bettary backup in this device is good but it takes a long time duration to full charge. And the storage of song collection is very bed only four gb songs can play in it. And the design is not more attractive. And according to the it’s price it have not sufficient features. And the the sound quality is average. But according to price it is poor. In it’s price range many types of best mp3 player are available in market. So I think my review will be useful for you. Thank you.
