I have been using the zebronics mp3 player since 2month here is my opinion regarding the product- sound quality is good but not the best. battery life keeps shrinking by each passing day .earlier with full charge, it used to lasts for 2 hours, now it only lasts for hardly an hour witch disturbs listening process while out or traveling. it’s earphone is are also very low quality. it is too slow as a card reader this is a basic player with memory and controls good for kids to play
