    I BOUGHT THIS ONE TO REPLACE MY OTHER SPEAKER THAT SEEMED TO ONLY STAY CHARGED FOR ABOUT 2 HOURS ON MAXIMUM VOLUME, THIS SPEAKER IS EVEN LOUDER AND HAS CRISP SOUND AND WE CAN USE IT BY THE POOL FOR HOURS ON MULTIPLE DAYS AND IT STAYS CHARGED, YOU CAN ALSO PRESS THE PLUS AND MINUS AND IT WILL TELL YOU BATTERY PERCENTAGE. 10/10 WOULD RECOMMEND!

    This speaker is pretty decent, battery life is good and once you downs load the app the usability is easy , it has a crisp sound but I wish it had better bass.

    Initially bought the miniboom. Did not play loud enough. This plays loud and sounds good. A little on the heavy side, but not overly cumbersome.
