Short answer: the Tronsmart Mirtune C3 Plus. It ranks #75 of 150 medium speakers by sound quality, rated 3.3/5, at $49.99; the Marshall Emberton II ranks #111, rated 2.7/5, and costs $159.99, so there is not much of a tradeoff to weigh.
Why pick the Tronsmart Mirtune C3 Plus: A racetrack woofer and a tweeter rated for 50W, with IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a detachable lanyard, at 0.81 kg. The catch: In side by side tests by Clinch Audio Bass and Mateusz Cholewa, the Xiaomi Sound Party and Soundcore Boom 3i sounded more refined and fuller, and listeners described the C3 Plus’s treble as dull.
The case for 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 C3 Plus. 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.
There is a real battery-life gap here: the Marshall Emberton II is rated for 30 hours, the Tronsmart Mirtune C3 Plus only 12 hours.
