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 ranks #89, rated 3.1/5, at $29.99, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.
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.
Why pick 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. The tradeoff: 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.
Buy the Soundcore Motion 300. It is rated higher for sound quality, and the $50 saving on the Tronsmart Mirtune C3 is not enough to make up the difference.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon eBay
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.
