Short answer: the Tronsmart Fiitune X30, if you are buying new. The EarFun Uboom X ranks higher than it (#1 vs #54 of 113 boombox speakers, 4.7/5 vs 3.3/5) but is discontinued, so only consider it used; the Tronsmart Fiitune X30 is still sold new at $144.90.
The UBoom X is far better. In a side by side sound test listeners found it more neutral and natural, while the X30 sounded muddy in the bass with dull, underemphasized treble.
The UBoom X is extremely neutral, reaches deeper than the Tribit Stormbox Blast and measured about 110dB, but it is discontinued. The X30 is still sold, with LDAC, IPX6 and a claimed 14 hours.
Evidence: The X30’s rating comes from listening comparisons, not measurements.
Buy the Tronsmart Fiitune X30, since the EarFun Uboom X is discontinued and only worth hunting down used.
