These are not really the same size class, and that is the honest framing here. The JBL Partybox 330 ranks #2 of 53 party speakers by sound quality at $629.95; the JBL Boombox 3 Wifi ranks #26 of 113 boombox speakers by sound quality at $389.95.
Why pick 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 JBL Boombox 3 Wifi cannot. It has an adjustable EQ, which the JBL Boombox 3 Wifi lacks. Watch for: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The JBL Boombox 3 Wifi is the longer-running, lighter choice. A big, waterproof stereo boombox with Wi-Fi, a long battery and enough volume for any outdoor party. It is rated for 24 hours of battery against 18 for the JBL Partybox 330. At 14.6 lbs (6.6 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. The tradeoff: Bass boosted.
Buy the JBL Partybox 330 at $629.95 for a party speaker, or the JBL Boombox 3 Wifi at $389.95 for a boombox speaker instead.
