Short answer: the JBL Partybox Encore Essential 2 on measured sound quality, the W-King H330 on price. The JBL Partybox Encore Essential 2 ranks #6 of 113 boombox speakers, rated 4.3/5, at $249.95. The W-King H330 ranks #32, rated 3.8/5, at $95.99, $153.96 cheaper.
The JBL Partybox Encore Essential 2 is the better-sounding, longer-running pick. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. It is rated for 15 hours of battery against 9 for the W-King H330. The catch: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The W-King H330 is the lighter, tougher option. 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 Partybox Encore Essential 2 at 13.7 lbs (6.2 kg). It is rated IPX7 against IPX4 for the JBL Partybox Encore Essential 2. The tradeoff: It isn’t very loud, and the W-King X20S plays louder with punchier bass.
Buy the JBL Partybox Encore Essential 2 when sound quality outweighs the price for you, and the W-King H330 when the price outweighs sound quality instead.
