I suggest everone who loves listening to songs full day it have very good battery backup and it also charges very fast. You can also connect this with your woofer or speakers if you have like I do. I purchased it 6 years back and I have no problem with it. Also it have enough memory for me to use. Its easy to use and every headfone or earphones are compatible with it. Also it is so small that you can carry it everywhere. All these qualities make it 5 star??
