So the JBL Xtreme 4 has some very big upgrades to it like a swappable battery, better sound and Auracast. And in general, this is a super portable and loud speaker thats great to take to the beach or park with you. However, the JBL Xtreme 4 is a little pricy especially when you compare it to either the Soundcore Boom 2 and especially the Soundcore Boom 2 Plus which both give you a very big bang for your buck. Either way, if you’re thinking about picking up the JBL Xtreme 4 or if you’re thinking about going with either the Soundcore Boom 2 Plus or even the Soundcore Boom 2… lets see which one is right for you.
