The sound quality of the ipod is very bad. I got a pain in my ears after listening to song with headphones. Zebronics should work on its sound. Because iPod is specially made for listening to songs, then why do you provide poor sound quality. Sour mango can be sold only once in the market. Speaking about the design, I would like to say that the design is good. The quality of plastic is also very bad. Battery is also very bad. Once the battery is charged fully, it only lasts for two hours. At last, I don’t like this product. Company should upgrade this.
