Short answer: the EarFun Uboom L. It ranks #2 of 179 medium speakers by sound quality, rated 4.6/5, at $49.79. The Tribit Stormbox Mini+ ranks #145, rated 2.5/5, at $39.99, $9.80 cheaper, a saving that is not big enough to make up the sound-quality gap.
The EarFun Uboom L is the better-sounding, longer-running choice. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. It is rated for 16 hours of battery against 12 for the Tribit Stormbox Mini+. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The case for the Tribit Stormbox Mini+: An inexpensive waterproof speaker packed with features, including app EQ, an aux input, microSD playback and stereo pairing. The tradeoff: Not a great sounding speaker, really weak bass.
Buy the EarFun Uboom L. It is rated higher for sound quality, and saving $9.80 with the Tribit Stormbox Mini+ does not make up for the sound-quality gap.
