JBL is the best speaker company. It’s wireless speaker is one of the best speaker . I purchase the JBL SPEAKER online worth Rs 6500 . Everyone of my family member suggest me not to purchase it, but when they hear the sound of speaker. Everyone told me that is a very good product and they praised me. JBL SPEAKER’S battery back is around 12 hrs. and it has also a port of usb so that you can also connect a pendrive with it. It shows the battery level in three lights .which are of blue in color. It looks like a pretty product. It is small in size and large in quality.
