Quick verdict

SOUNDBOKS builds battery-powered party speakers that are seriously loud and nearly indestructible. The Soundboks 4 is the flagship: RTINGS called it exceptionally loud (score 7.2, October 2026) and measured 32.5 hours of battery life. It has two XLR/TRS inputs for mics or instruments, links up to 5 speakers, and uses a swappable LiFePO4 battery shared across the whole lineup. The newer Mix ($799) replaced the discontinued Go and earned 8/10 from WIRED, which dropped one off a patio without harm.

The honest part: the Soundboks 4 now costs $1,199 (it was $999). Its 126 dB claim is a peak figure; Outeraudio measured 111.2 dB at 1 meter, and WIRED measured the Mix at 111 dB versus 121 dB claimed. There’s no charger in the box ($69 extra), the charger can’t run the speaker as a plug-in power supply, it plays in mono over basic Bluetooth, and battery wear isn’t covered by the warranty.

Our picks: Soundboks 4 if you need the loudest, most connectable rig. Mix for most parties. Rider ($599) if you want the smallest and toughest, without speaker linking.

Pros

✓ Exceptionally loud for a battery speaker (RTINGS)
✓ Soundboks 4: 32.5 hours of battery in RTINGS’ test; 2 XLR/TRS inputs

Cons

✗ Soundboks 4 now $1,199 (was $999)

✗ Mono sound, older Bluetooth (5.0 / 4.2), SBC only
✗ Battery wear excluded from warranty; battery failures a recurring complaint
✗ Trustpilot 3.9 (3,206 reviews) with unanswered negative reviews

Prices from soundboks.com on November 1, 2026. Tom’s Guide still quoted the Soundboks 4 at $999 in June 2026; we couldn’t find why it rose. Refurbished units are sometimes listed for less.

How loud is SOUNDBOKS, really?

Model	Claimed	Measured	Who measured
Soundboks 4	126 dB	111.2 dB	Outeraudio
Mix	121 dB	111 dB	WIRED

SOUNDBOKS’ numbers are peak claims. Measured at 1 meter, it still plays very loud, which is why RTINGS calls the Soundboks 4 exceptionally loud, but expect roughly 10 to 15 dB less than the box says. Every model plays in mono.

Battery, charging and the plug-in catch

Swappable battery: one LiFePO4 battery works in the Soundboks 4, Mix and Rider. A spare costs $199, so you can swap mid-party.
No charger included: The Charger costs $69 and isn’t in the box on any model.
Not a plug-in speaker: SOUNDBOKS’ own help center says “the charger is NOT a power supply,” and the speaker can shut off around volume 6 to 11 if you run it on the charger alone. Keep a charged battery in it.
Battery life: RTINGS measured 32.5 hours on the Soundboks 4.

Warranty, returns and shipping

Warranty (US): 2 years, plus 1 more year when you register in the app. “Normal wear and tear on parts like batteries” isn’t covered, and units from unauthorized resellers aren’t covered at all. (WIRED’s “five-year warranty” mention doesn’t apply to the US.)
Returns: 45 days on speakers with a prepaid return label; 30 days on other products. The refund policy page doesn’t list the Rider in its 45-day list, so confirm before buying.
Shipping: free on speakers, usually shipped in 1 to 2 business days; Hawaii and Alaska cost $100.

Company, support and safety

SOUNDBOKS started in Copenhagen in 2015 after a Kickstarter campaign and has raised roughly $20 to $23 million. Trustpilot shows 3.9 from 3,206 reviews, and the page notes the company hasn’t replied to negative reviews; complaints focus on slow email support, shipping delays and failed batteries. In 2022, SOUNDBOKS recalled about 6,700 Gen 3 lithium-ion batteries over fire hazard (no incidents reported). We found no recalls for the current models and no BBB profile.

SOUNDBOKS vs JBL PartyBox, Bose and Sony

Speaker	Price	Notes
Soundboks Mix	$799	Rugged, swappable battery, links 5
Soundboks 4	$1,199	Loudest SOUNDBOKS, XLR inputs
JBL PartyBox Stage 320	about $499.95	Light show; price from search snapshot
JBL PartyBox 520	about $879.95	Price from search snapshot
Bose S1 Pro+	$699	Portable PA, confirmed on bose.com
Sony ULT Tower 10	about $1,199	Price from launch coverage

JBL and Sony prices are from search snapshots and launch coverage because their sites blocked our live check, so confirm before buying. JBL’s PartyBox line adds light shows for less money; SOUNDBOKS wins on toughness, swappable batteries and multi-speaker linking.

Who should buy SOUNDBOKS

Good fit: outdoor parties, tailgates, beach and boat days, DJs and bands who need a rugged battery PA with mic inputs.
Skip it if: you want stereo sound, plug-in use without batteries, the newest Bluetooth codecs, or the most speaker for your money (look at JBL PartyBox).
