These are not really the same size class, and that is the honest framing here. The JBL Partybox 110 ranks #9 of 53 party speakers by sound quality at $379.95; the Zealot ZE51 ranks #16 of 113 boombox speakers by sound quality at $235.33.
The JBL Partybox 110 is the longer-running option. A party speaker with very neutral sound and solid bass, a great pick for backyard parties. It is rated for 12 hours of battery against 4 for the Zealot ZE51. Watch for: Bass isn’t as deep as the JBL Partybox 100.
What the Zealot ZE51 does well: A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
Buy the JBL Partybox 110 ($379.95) for a party speaker; the Zealot ZE51 ($235.33) suits a boombox speaker instead.
