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 EcoXGear Defender ranks #85 of 113 boombox speakers by sound quality at $299.99.
Different sizes. The PartyBox 330 is a 37.7 lbs (17.1 kg) party speaker. The Defender is a 9.9 lbs (4.5 kg) boombox. Each is rated within its own class.
The Defender is built for the outdoors, with IP67, a floating design, a flashlight, a bottle opener and a claimed 25 hours. It gets very loud for its size, but its single front driver has narrow dispersion and bass does not reach as deep as competitors. It has no app.
The PartyBox 330 has a removable battery, wheels, lights, Auracast, optical and USB-C inputs, and dual mic and guitar inputs. It is IPX4.
Buy the JBL Partybox 330 ($629.95) for a party speaker; the EcoXGear Defender ($299.99) suits a boombox speaker instead.
