Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 330 ranks #2 of 53 party speakers by sound quality at $629.95; the Tribit Stormbox Blast 2 ranks #31 of 113 boombox speakers by sound quality at $279.99.
The case for the JBL Partybox 330: A rolling party speaker with deep bass, a removable battery, a light show and inputs for mics and a guitar. It links with other speakers (Auracast), which the Tribit Stormbox Blast 2 cannot. The tradeoff: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The Tribit Stormbox Blast 2 is the longer-running, lighter choice. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. It is rated for 30 hours of battery against 18 for the JBL Partybox 330. At 19.2 lbs (8.7 kg) it weighs much less than the JBL Partybox 330 at 37.7 lbs (17.1 kg). It is rated IP67 against IPX4 for the JBL Partybox 330. Watch for: Sounds quite muddy with the boosted lower and upper bass.
Buy the JBL Partybox 330 at $629.95 for a party speaker, or the Tribit Stormbox Blast 2 at $279.99 for a boombox speaker instead.
