Short answer: the Soundcore Motion 300. It ranks #3 of 182 medium speakers by sound quality, rated 4.5/5, at $79.99; the Tronsmart Mirtune S100 ranks #97, rated 3.1/5, at $79.99. With prices this close, go by the sound-quality ranking rather than the cost.
The Soundcore Motion 300 is the better-sounding, deeper-bass pick. A compact stereo speaker with deep bass for its size, hi res Bluetooth and a custom EQ for each position, standing or lying down. Its bass reaches about 50Hz before falling 10dB, against 64Hz for the Tronsmart Mirtune S100. At 1.7 lbs (772 g) it weighs much less than the Tronsmart Mirtune S100 at 3 lbs (1.36 kg). It supports LDAC Bluetooth, which the Tronsmart Mirtune S100 lacks. 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.
The Tronsmart Mirtune S100 is the longer-running pick. A waterproof speaker with long battery life for outdoor and casual listening. It is rated for 20 hours of battery against 13 for the Soundcore Motion 300. It keeps a wired aux input, which the Soundcore Motion 300 lacks.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Tronsmart Mirtune S100 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
