Our Verdict

JBL Boombox 3

Ultimate Ears EPICBOOM

The JBL Boombox 3 is a better choice for music than the Ultimate Ears EPICBOOM. The JBL reproduces a bit more low bass, making you feel more thump and rumble in the mix. It also gets louder with less compression at max volume. Plus, its battery life lasts longer. The Ultimate Ears has additional customization tools, like an Adaptive EQ room calibration tool and more preset modes.
