Short answer: the Zealot ZE21 for value, the LG Xboom Stage 301 for karaoke. The LG’s wedge design works as a karaoke hub with a removable, replaceable battery, but the source calls it overpriced for what it is. The ZE21 is a great value for bass, play time and max volume, though the ZE41 beats it and it is a little rolled off up top.
Buy the Zealot ZE21. It is rated higher for sound quality, and the $17.42 you would save on the LG Xboom Stage 301 does not close the gap.

The Two Speakers In Full
Zealot ZE21: $247.41 Amazon AliExpress eBay
Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).
Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.
