Short answer: the Soundcore Boom 3i. It ranks #29 of 144 medium speakers by sound quality, rated 4.0/5, at $118.99. The Tronsmart Mirtune S100 ranks #79, rated 3.1/5, at $79.99, $39 cheaper, which does not close the gap in sound quality.
What the Soundcore Boom 3i does well: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. The catch: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Why pick the Tronsmart Mirtune S100: At 1.36 kg, Tronsmart Mirtune S100 combines 20W drivers with Bluetooth. The tradeoff: Bass is limited by its ~64Hz specification.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and the $39 saving on the Tronsmart Mirtune S100 is not enough to make up the difference.
