Short answer: the Ultimate Ears Boom 4, though neither ranks well in its class. It ranks #99 of 150 medium speakers by sound quality, rated 2.9/5, at $109.99. The Limitless Innovations TikiTunes ranks #150, rated 2.0/5, at $40, $69.99 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Why pick the Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. Watch for: Not much improvement over the old ones.
What the Limitless Innovations TikiTunes does well: Distinctive flickering-flame LED design: the most-praised feature in owner reviews. The tradeoff: Pretty much no bass at all, weird tuning.
Buy the Ultimate Ears Boom 4. It is rated higher for sound quality, and saving $69.99 with the Limitless Innovations TikiTunes does not make up for the sound-quality gap.
