Short answer: the Soundcore Boom Go 3i. It ranks #2 of 62 small speakers by sound quality, rated 4.4/5, at $79.99. The Xiaomi Sound Pocket ranks #60, rated 2.3/5, at $20.99, $59 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Boom Go 3i is the better-sounding, longer-running choice. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It is rated for 24 hours of battery against 10 for the Xiaomi Sound Pocket. The tradeoff: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic.
The Xiaomi Sound Pocket is the lighter option. A truly pocketable, very cheap waterproof speaker with USB-C charging and stereo pairing, fine for hotel rooms and travel. At 0.4 lbs (200 g) it weighs much less than the Soundcore Boom Go 3i at 0.8 lbs (380 g). The tradeoff: Its 5W driver has little real bass, and vocals can become harsh as volume rises beyond roughly 80%.
Buy the Soundcore Boom Go 3i. It is rated higher for sound quality, and saving $59 with the Xiaomi Sound Pocket does not make up for the sound-quality gap.
