Our Verdict

JBL Flip 6

Ultimate Ears WONDERBOOM 4

The Ultimate Ears WONDERBOOM 4 and JBL Flip 6 are both very portable speakers with different pros and cons, so the best one depends on your needs. The Ultimate Ears has a significantly longer battery life, better 360-degree directivity, lower latency for watching videos, and less compression. However, the JBL has app support with a custom EQ to adjust the sound and a bit more low-end extension.
