Short answer: the Tronsmart Mirtune C3. It ranks #89 of 150 medium speakers by sound quality, rated 3.1/5, at $29.99; the Marshall Emberton II ranks #111, rated 2.7/5, and costs $159.99, so there is little reason to consider the other one.
The case for the Tronsmart Mirtune C3: Small and light at 530 g, with a racetrack driver and a tweeter rated for 30W, IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a lanyard. Watch for: In GiT’s three way blind test it came behind the Creative Muvo Go and Xiaomi Sound Outdoor, sounding good only on sparse tracks, and listeners in AudioPro Reviews’ comparison found the JBL Flip 6 fuller with more bass.
What the Marshall Emberton II does well: 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. It is rated higher for sound quality than the Marshall Emberton II and costs less, which makes it the one to get unless you need something the other one does better.
If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Tronsmart Mirtune C3.
