Soundcore Boom 2
$60 under your budget
SoundGuys' grab-and-go pick — 3.7 lbs, IPX7 and floatable, 24 hours of battery and 80W, for the speaker one person actually carries to a beach or a campsite.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
80W does not throw a party. This is a personal and small-group speaker: it will not cover a 50-person backyard, and it has no mic and no instrument input, so karaoke and a live guitar are out. Buy it as the speaker that goes everywhere with you — the moment the guest list passes about a dozen, you are buying the wrong class of speaker.
Dealbreaker? Klipsch Gig XXL is ~$80 and clears 100 dB, indoors ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Soundcore Boom 2 is right for you
It avoids every trap below — and for just me, under $150, it is the pick because it delivers:
"Watts" means nothing here
Every brand quotes a different measure. Marshall reports total amplifier output (400W), JBL reports system RMS (160W-400W), Klipsch reports 80W RMS, Soundcore reports a BassUp-boosted maximum (140W), and Sony and Ultimate Ears publish no wattage at all. A 400W Marshall and a 400W JBL are not the same speaker. Where a reviewer publishes measured SPL, use that instead: RTINGS measures the $80 Klipsch Gig XXL above 100 dB, and the JBL Boombox 4 is rated at 105 dB.
The battery figure is measured at half volume
Quoted runtimes assume roughly 50% volume with the lights off. Run a real party — high volume, bass boost, LEDs on — and battery life drops 40-60%, so a 30-hour Sony is a 15-hour Sony. Battery speakers also get audibly quieter as the pack drains. One exception on this page: Klipsch quotes the Gig XXL's 8 hours at full volume, which is the honest way to publish it. For anything longer than an evening, plan on AC power.
IPX4 is not an outdoor rating
IPX4 means splash-resistant only — the JBL PartyBox 520, Stage 320, PartyBox 110 and UE HYPERBOOM are all IPX4 and do not belong in rain or near a pool. IP67 survives 1 m of submersion for 30 minutes; IP68 goes deeper. And the Klipsch Gig XXL publishes no IP or water rating at all on Klipsch's own spec page — treat it as an indoor or covered-patio speaker.
