Last updated: August 19, 2026

Short answer: the Xiaomi Mi Portable. It ranks #58 of 136 medium speakers by sound quality at $55; the Sony XB33 ranks #59 and costs $110, so there is not much of a tradeoff to weigh.

The case for the Sony XB33: IP67 rated and lightweight (2.4 lb). App-controlled color LED lighting, Party Connect links up to 100 speakers. ~19 hour real-world battery without lights. Watch for: Not very loud. Upper bass peaks, midrange dip, upper midrange peaks, not very neutral.
