I bought several speakers (JBL Charge 3, AY Bluetooth 5.0, Altec H20 4 and this UE Boom 3) for my super picky rock music-obsessed husband. He wanted a powerfully loud speaker that still gave good bass while not fading the guitars. JBL and Altec were loud, but not loud enough and not enough bass. AY didn't measure up at all. UE Boom 3 knocked it out of the park!! This speaker is the loudest, clearest and best sounding out of all of them. Plus it comes with an equalizer app to tweak anything you may prefer. My husband absolutely loves this speaker!! :)
