Short answer: the Xiaomi Mi Portable Mini, because it brings far more features for a tiny speaker. It is IP67 waterproof, pairs in TWS stereo, runs 10 hours on Bluetooth 5.0 and weighs 185g, with a bass boost equalizer. The Monster is quite light for its performance, but both are short on bass, and the Monster adds mids that are slightly boosted and highs that are a little rolled off.
What the Monster Bluetooth Speaker gets right: Quite light for the performance. The tradeoff: Not much bass, mids slightly boosted, highs a little rolled off.
On the Xiaomi Mi Portable Mini side: IP67 waterproof, TWS stereo pairing, 10-hour battery life, Bluetooth 5.0, compact 185g design, bass boost equalizer. The catch: Not much bass, treble rolled off.
Buy the Monster Bluetooth Speaker. It ranks higher for sound quality than the Xiaomi Mi Portable Mini and costs less, so there is no real case for the other one.
The Xiaomi Mi Portable Mini is not a sound-quality pick. It sits near the bottom of the 47 small speakers; there are better options higher up.

The Two Speakers In Full
Monster Bluetooth Speaker: $19.99 Amazon eBay
Pros: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS pairing. It is a convenient rugged travel speaker when water resistance and small size matter more than bass. Measured bass extension of 95Hz (-10dB).
Cons: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs. It cannot deliver the scale, detail or battery endurance of stronger small-speaker rivals, and no app or EQ is available to improve the tuning.
