This is a very cheap mp3 player and also feels pretty cheap. but the its performance is pretty fair for the price. it have a micro sd card slot for the storage purpose and it plays music directly from the external card. the music quality played is fair and it is pretty loud also. it supports universal 3.5 mm headphone jack which is incredible for those of who want to use their favorite headphones. it supports an old type of mini headphone jack which is not universal but the include the data cable. the battery life is also pretty fare of about 4
