Hello friends. I am going to review this mp3 player Zebronics sigma Two. This mp3 gave me a lot pf trouble. I bought it long back and this batter backup is very bad. It almost comes around only for few hours around 2-3 hours. When it comes to sound quality it is really really bad. The zebronics company has given some cheap quality earpones and it gives a rubbish sound quality of the music. The built up was ok but did not come to my expectations. Picture quality was bad and as I said battery backup is low. So guys please think twice before buying an mp3. I hope you find this review very helpfull. Thank you.
