JBL Boombox 3 vs Soundboks Go

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

JBL Boombox 3 and Soundboks Go score essentially the same (4.5 vs 4.5). Pick the one whose trade-offs match your priorities — the strengths and watch-outs below are where they actually differ.

Ranked #1 in Best Outdoor Bluetooth Speakers

JBL Boombox 3

4.5

$499

The Boombox 3 is the default backyard-party pick for buyers who want serious volume in a self-contained battery-powered box. Tom's Guide, SoundGuys, and Stereoguide all agree it sounds wide, loud, and bass-heavy without distorting at the top of its volume range, and the IP67 rating plus 24-hour battery let it run a daytime cookout that rolls into a night hang without ever needing to stop. Trade-offs are the weight and a missing multipoint feature reviewers flagged at launch.

Strengths

— 180W total output on AC (136W on battery) genuinely fills a backyard or driveway
— IP67 dust and water rating shrugs off pool splashes and sudden downpours
— 24-hour rated battery comfortably covers an all-day BBQ on a single charge

Watch-outs

— 14.7 lb (6.7 kg) with a hard metal handle — not a one-hand carry to the park
— Bluetooth multipoint is advertised but reviewers report it doesn't reliably work
— App EQ is a basic three-band slider with no per-frequency control

Ranked #5 in Best Outdoor Bluetooth Speakers

Soundboks Go

4.5

$699

The Soundboks Go is the speaker for buyers who measured their existing JBL or UE setup at a backyard party and decided it wasn't loud enough. RTINGS, TechHive, and GearJunkie all confirm it's overpowering for indoor use and ideal for genuine outdoor entertaining — backyard concerts, tailgates, lakeside parties. The 20 lb weight and $699 price put it in a different category than the rest of this list, but for the actual loudness use case, no other speaker here competes.

Strengths

— 121 dB maximum SPL — the loudest portable Bluetooth speaker in this list by a wide margin
— 144W class-D amplification with a 10-inch woofer for genuine bass impact at distance
— Replaceable, swappable batteries — 40 hours at mid-volume, 10 hours at maximum SPL

Watch-outs

— 20 lb (9 kg) and roughly the size of a small kick-drum — needs a shoulder strap to carry
— IP65 rating only — not safe for submersion or sustained rain
— $699 MSRP is more than 2x the Xtreme 4 or Hyperboom

How they stack up

JBL Boombox 3

The Boombox 3 delivers more raw output (180W AC / 136W battery) than the smaller JBL Xtreme 4 (70W battery / 100W AC) and the Bose SoundLink Max, but the UE Hyperboom edges past it on stereo soundstage thanks to its larger cabinet, and the Soundboks Go hits a much higher peak SPL (121 dB vs the Boombox 3's roughly 100 dB territory). Pick the Boombox 3 over the Hyperboom if you want a true battery + handle combo you can carry to the lake — the Hyperboom's IPX4 rating and heavier static form factor are happier on a patio.

Soundboks Go

The Soundboks Go is the only speaker in this list that genuinely competes with PA equipment — its 121 dB max SPL is roughly 10–15 dB louder than the JBL Boombox 3 or UE Hyperboom, and 20+ dB louder than the JBL Xtreme 4 or Bose SoundLink Max. The cost is portability and price: at 20 lb it's the heaviest by a wide margin, and the $699 MSRP is 75–100% above the Hyperboom and Boombox 3. There's also genuine dissent in reviewer opinions — LBTech found the sound harsh at high volumes where TechHive and GearJunkie praised it.
