Short answer: the Tronsmart Mirtune S100. It ranks #84 of 150 medium speakers by sound quality, rated 3.1/5, at $79.99; the Marshall Emberton II ranks #111, rated 2.7/5, and costs $159.99, which makes this an easy call rather than a real tradeoff.
The case for 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.
Why pick the Marshall Emberton II: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Tronsmart Mirtune S100. It is rated higher for sound quality than the Marshall Emberton II and costs less, so only choose the other one for a particular feature it does better.
