Short answer: Zealot PT21 is the bass-and-karaoke value play, while JBL Partybox 110 is the safer choice for a neutral party-speaker sound. The Zealot uses dual 166mm woofers and includes a wireless mic, but its app EQ support is uncertain; JBL gives up some bass depth for a more balanced presentation.
Buy the Zealot PT21 if deep bass and bundled karaoke hardware are your priorities.
Buy the JBL Partybox 110 if you want the more neutral-sounding party speaker.
Battery life favors the Zealot PT21: rated for 60 hours against 12 hours for the JBL Partybox 110.
