These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 40 party speakers by sound quality at $499.95; the EcoXGear Defender ranks #60 of 76 boombox speakers by sound quality at $303.38.
Different sizes. The Stage 320 is a 16.5 kg party speaker. The Defender is a 4.5 kg boombox. Each is rated within its own class.
The Defender is IP67, floats, and claims 25 hours. It gets very loud for its size, but narrow dispersion and shallow bass limit it, and it has no app or party mode.
The Stage 320 keeps more bass at high volume than the PartyBox 310, and has wheels, a removable battery, mic and guitar inputs and Auracast. It is IPX4.
Buy the JBL Partybox Stage 320 at $499.95 for a party speaker, or the EcoXGear Defender at $303.38 for a boombox speaker instead.

EcoXGear Defender: $303.38 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.
