Short answer: the Muzen Wild Go, if you are buying new, though neither ranks well in its class. The Sony SRS-XB13 ranks higher than it (#36 vs #43 of 49 small speakers, 2.8/5 vs 2.4/5) but is discontinued, so only consider it used; the Muzen Wild Go is still sold new at $45.99. Both are rated below 3.0/5 among the 49 small speakers, so if sound quality matters, consider the Tribit Stormbox Micro 2 instead, ranked #1 at $49.99.
What the Sony SRS-XB13 does well: Sony SRS-XB13 uses 46mm. Watch for: Bass is limited by its 88Hz specification.
Why pick the Muzen Wild Go: Distinctive retro military-radio design with an all-metal (zinc alloy) body: feels far more solid than the plastic speakers in this class. The tradeoff: Not much bass at all, quite thuddy.
Buy the Muzen Wild Go if you want one new; the Sony SRS-XB13 is discontinued, so only look for it used.
