Same family: the Tronsmart Mirtune S100 (smaller model, ranked lower, rated 3.1/5), the Tronsmart Mirtune C3 (smaller model, ranked lower, rated 3.1/5) and the Tronsmart Mirtune H1 (larger model, rated 3.4/5).

Pros: An affordable waterproof speaker with a separate tweeter, app EQ, Auracast linking, stereo pairing and USB-C audio input. 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.

Cons: 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. Oluv also found it cheap sounding and lacking refinement, and none of its EQ presets fixed that. Tronsmart rates the battery at only 12 hours at half volume. It is a mono unit with no aux input.
