Short answer: the JBL Partybox 300, on clarity. Both go deep, but the 300 earns its keep with crisp, crystal clear highs and midranges plus hard punchy bass that stays free of muddiness, while the Tribit Stormbox Blast 2 sounds quite muddy from its boosted lower and upper bass. The JBL is the harder one to live with: it is hard to carry, too tall and drags on the ground.
One note: the JBL Partybox 300 is no longer sold new, but at #10 of 53 party speakers by sound quality it still outranks most current models, so used is worth considering. The JBL Partybox 300’s replacement, the JBL Partybox 330, is rated 4.6/5 at $629.95.
Buy the JBL Partybox 300 at $300 for a party speaker, or the Tribit Stormbox Blast 2 at $279.99 for a boombox speaker instead.
Battery life favors the Tribit Stormbox Blast 2: rated for 30 hours against 18 hours for the JBL Partybox 300.
Water resistance is not close: the Tribit Stormbox Blast 2 is rated at IP67 (brief submersion), well ahead of the JBL Partybox 300 at no water resistance.
