Short answer: the JBL Grip. Both are rated 3.1/5 for sound quality (#98 and #97 of 179 medium speakers), and the JBL Grip costs $69.95 against $79.99 for the Tronsmart Mirtune S100, with sound quality a draw, the lower price decides it.
The Tronsmart Mirtune S100 is the longer-running choice. A waterproof speaker with long battery life for outdoor and casual listening. It is rated for 20 hours of battery against 14 for the JBL Grip. It keeps a wired aux input, which the JBL Grip lacks.
The JBL Grip is the lighter choice. A small, fully waterproof speaker with app EQ, ambient lighting, Auracast linking and USB-C audio input. At 0.8 lbs (385 g) it weighs much less than the Tronsmart Mirtune S100 at 3 lbs (1.36 kg). Watch for: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
Buy the JBL Grip. Both are rated the same for sound quality, and it costs $10.04 less than the Tronsmart Mirtune S100.
