Soundcore Motion 300 vs Tronsmart Mirtune C3 Plus

Last updated: September 30, 2026

Short answer: the Soundcore Motion 300. It ranks #2 of 150 medium speakers by sound quality, rated 4.5/5, at $79.99. The Tronsmart Mirtune C3 Plus ranks #75, rated 3.3/5, at $49.99, $30 cheaper, which does not close the gap in sound quality.

Soundcore Motion 300 vs Tronsmart Mirtune C3 Plus

The case for the Soundcore Motion 300: Pretty deep bass for the small size. Watch for: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.

What the Tronsmart Mirtune C3 Plus does well: 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 tradeoff: 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.

Buy the Soundcore Motion 300. It is rated higher for sound quality, and saving $30 with the Tronsmart Mirtune C3 Plus does not make up for the sound-quality gap.

Soundcore Motion 300 ranking card

Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5).

Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Measured bass extension of 50Hz (-10dB).

Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
