Our Verdict

Ultimate Ears BOOM 4

LG xboom Grab

The LG xboom Grab and the Ultimate Ears BOOM 4 are highly portable Bluetooth speakers with slightly different strengths. The Ultimate Ears features a 360-degree design, providing consistent sound from all angles, doesn't downmix your audio to mono, gets louder, and boasts a slightly longer battery life. On the other hand, the LG offers a more balanced default sound (though you can EQ both speakers in their companion apps) with greater punch in the bass. It also supports your phone's Siri or Google Assistant, unlike the Ultimate Ears. The choice really comes down to your particular priorities.
