Short answer: the JBL Flip 6. It ranks #13 of 182 medium speakers by sound quality, rated 4.2/5, at $114.95. The Tronsmart Mirtune S100 ranks #97, rated 3.1/5, at $79.99, $34.96 cheaper, which does not close the gap in sound quality.
The JBL Flip 6 is the better-sounding, deeper-bass pick. A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. Its bass reaches about 56Hz before falling 10dB, against 64Hz for the Tronsmart Mirtune S100. At 1.2 lbs (544 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: Some slight upper mids emphasis.
The Tronsmart Mirtune S100 is the longer-running pick. A waterproof speaker with long battery life for outdoor and casual listening. It is rated for 20 hours of battery against 12 for the JBL Flip 6. It keeps a wired aux input, which the JBL Flip 6 lacks.
Buy the JBL Flip 6. It is rated higher for sound quality, and saving $34.96 with the Tronsmart Mirtune S100 does not make up for the sound-quality gap.
