Sometimes you want a speaker that can shake the walls, but other times you want something compact that still delivers. That's where the JBL Go 4 shines. It packs impressive sound in a tiny, travel-friendly design -- perfect for music on the go, like when you don't want to blast it to the entire beach.
CNET's David Carnoy ranks it the best pocket-friendly Bluetooth speaker and says, "The speaker can only deliver so much sound for its tiny size (don't get your expectations up too high), but it sounds better than you think given just how small it is (it truly fits in a pocket) and manages to output just enough bass to avoid sounding tinny."
