Short answer: the Wonderboom 4 on price, the LG Xboom Grab on battery. The Grab’s 20 hour battery is its main argument, but the Wonderboom 4 costs $26.04 less and is small enough to carry easily. Both fall short on bass, and the Wonderboom 4’s is a little thuddy.
Buy the LG Xboom Grab. It is rated higher for sound quality, and saving $26.04 with the Ultimate Ears Wonderboom 4 does not make up for the sound-quality gap.

Older models: the Ultimate Ears Wonderboom 3 (ranked lower, rated 2.9/5), the Ultimate Ears Wonderboom 2 (ranked lower, rated 2.9/5) and the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5).
Pros: Small size.
