Short answer: the Monster Bluetooth Speaker. It ranks #39 of 62 small speakers by sound quality, rated 3.0/5, at $19.99; the Xiaomi Sound Pocket ranks #60, rated 2.3/5, and costs $20.99, so there is little reason to consider the other one.
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 Sound Pocket side: 5W output, IP67 waterproof, 10-hour battery life, compact 0.4 lbs (200 g) ultra-portable design, Bluetooth 5.4 with TWS stereo pairing. Set against that: Bass light, vocals harsh above ~80% volume, vibrates/walks on hard surfaces at higher volume when upright, slow 3-hour charge.
Buy the Monster Bluetooth Speaker if aux input and microSD playback are essential and you want the smallest spend.
Buy the Xiaomi Sound Pocket if water protection, USB-C and a longer claimed battery are more useful, keeping volume below the point where vocals become harsh.
