The earphones delivered with the product are not that good, You will have to invest in a good quality of earphone. The sound is excellent. I use a good quality earphone, gives a very decent output. And different sound equalizer helps it to give more perfect sound.
It is very good product. Very affordable and a good battery backup. Battery life is very good, charging time is less. It has 4 GB of space and you can also listen to fm, and audio recording option is also available.
Best mp3 player at this price.
