Short answer: the W-King H330. Both are rated 3.8/5 for sound quality (#32 and #27 of 113 boombox speakers), and the W-King H330 costs $95.99 against $349.95 for the JBL Boombox 3, with sound quality a draw, the lower price decides it.
The JBL Boombox 3 is the longer-running choice. A loud, fully waterproof boombox with a dedicated subwoofer, a 24 hour battery and power bank charging. It is rated for 24 hours of battery against 9 for the W-King H330. The catch: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
The W-King H330 is the lighter choice. An affordable boombox with deep, full bass for its size, clean vocals, and fast USB-C charging. At 9.9 lbs (4.5 kg) it weighs noticeably less than the JBL Boombox 3 at 14.8 lbs (6.7 kg). It has an adjustable EQ, which the JBL Boombox 3 lacks. The catch: It isn’t very loud, and the W-King X20S plays louder with punchier bass.
Buy the W-King H330. Both are rated the same for sound quality, and it costs $253.96 less than the JBL Boombox 3.
