this headphone is awesome its price the battery back is good and you can be carefree of battery as you get an aux cable with it through which u can connect it through phone and listen to music when battery runs out the buttons on side are so helpful that you dont have to take out your phone the range of bluetooth is also great it has comfortable earbuds the only problem may be little with the loosening of headset and it may fall of your head if you are not careful
