Short answer: the JBL Charge Essential. It ranks #78 of 150 medium speakers by sound quality, rated 3.2/5, at $73.99; the Tronsmart Mirtune S100 ranks #84, rated 3.1/5, and costs $79.99, so there is little reason to consider the other one.
What the JBL Charge Essential does well: Doubles as a power bank. The tradeoff: Less clarity than the Flip 4, highs rolled off.
Why pick the Tronsmart Mirtune S100: At 1.36 kg, Tronsmart Mirtune S100 combines 20W drivers with Bluetooth. The catch: Bass is limited by its ~64Hz specification.
Buy the JBL Charge Essential. It is rated higher for sound quality than the Tronsmart Mirtune S100 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
