Hii friends. I am using this headphones from last 1 year. Its sound quality is awesome. And the battery back up is about 6 hours . And the charging time is 3 hours.but only the problem with this headphone is that is not comfortable while you are using it on sleeping time. Its body is made up of hard plastic and less chances of broken. And also a memory card is inserted in it. Its also used as calling purpose having mike. I mostly used it on workout time. And I really enjoy the sound quality and it is realeable and easy to carry and occupie less space to fit in your bag.this is old but good than other brands.
Thank you
