Short answer: the Zealot ZE21 if sound quality matters most, the Skullcandy Barrel if price matters most. The Zealot ZE21 ranks #17 of 75 boombox speakers at $247.41. The Skullcandy Barrel ranks #41 at $159, $88.41 cheaper.
What the Zealot ZE21 offers: 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. Watch for: 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.
What the Skullcandy Barrel offers: Water-resistant (IPX5) with LED lightshow synced to music. 12 hour battery life. Bass Boost mode. Multi-Link feature connects up to 99 speakers. Doubles as phone charger. Watch for: Not as deep bass as the top ranked speakers. Not as loud as the top ranked speakers. Rolled off treble.
Buy the Zealot ZE21 if sound quality is the priority over the price, or the Skullcandy Barrel if the price is the priority over sound quality.

Zealot ZE21: $187.15 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.
