These are not really the same size class, and that is the honest framing here. The Soundcore Boom Go 3i ranks #2 of 62 small speakers by sound quality at $59.98; the Xiaomi Sound Party ranks #20 of 179 medium speakers by sound quality at $135.84.
The Soundcore Boom Go 3i is the lighter choice. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. At 0.8 lbs (380 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). The catch: 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.
What the Xiaomi Sound Party does well: A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. The tradeoff: The sound evidence is mixed rather than universally glowing.
Buy the Soundcore Boom Go 3i ($59.98) for a small speaker; the Xiaomi Sound Party ($135.84) suits a medium speaker instead.
