First, you have to be clear about where you want to use an outdoor speaker. Because there is no wall and ceiling to reflect the sound, a small to medium size speaker may never deliver the sound effect you want in a big open space. A bluetooth speaker may never fit a rock concert. However, if you just want to bring a speaker to add some vibe to your party, all you need to care about is its durability, sound quality and battery life. soundcore outdoor speakers check all the marks, offering all you need in an outdoor speaker that you can dance to and vibe to.
