Short answer: the Tronsmart Mirtune S100. It ranks #97 of 179 medium speakers by sound quality, rated 3.1/5, at $79.99. The Tribit Stormbox 2 ranks #104, rated 3.0/5, at $69.99, $10 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Tronsmart Mirtune S100: A waterproof speaker with long battery life for outdoor and casual listening. The catch: Bass is limited by its ~64Hz specification.
The Tribit Stormbox 2 is the lighter pick. A light, waterproof everyday speaker with a long rated battery and an Xbass mode that fills out the low end. At 1.3 lbs (593 g) it weighs much less than the Tronsmart Mirtune S100 at 3 lbs (1.36 kg). It supports AAC Bluetooth, which the Tronsmart Mirtune S100 lacks. The tradeoff: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the Tronsmart Mirtune S100. It is rated higher for sound quality, and the $10 you would save on the Tribit Stormbox 2 does not close the gap.
