LG Xboom Grab vs Ultimate Ears Boom 4

Last updated: October 1, 2026

Short answer: the LG Xboom Grab, for its 20 hour battery. It runs longer than the Boom 4’s 15 hours and matches its IP67 rating with elastic mounting straps, while the Boom 4 adds USB-C charging and floats. The Boom 4 has weak, thuddy bass and is not much of an improvement over the older Booms, and the Grab’s bass extension is not as deep as the top speakers either.
