Looks a lot like SOUNDBOKS 3, but it sounds and feels nothing like it.


Improved audio with more bass and crystal-clear sound even at max volume.


Our battery plays even longer now! Get ready to pull an all-nighter (or two in a row).


The new grill pops off and back on again in a moment. Paint it, spray it, make it yours.


While it may look familiar on the outside, SOUNDBOKS 4 has been meticulously redesigned and rebuilt for superior performance. Be prepared to take your music adventures to the next level. SOUNDBOKS 4 will power your party with incredibly immersive sound at 126 dB, for up to 40 hours on a single charge.


    We’ve drastically improved the audio performance and quality. We’ve implemented a much more powerful Digital Signal Processor (the “brain” behind all the internal audio handling), redesigned our speaker drivers for better bass, mids, and highs as well as refactored our audio routing and firmware altogether.


    What you’re seeing (and hearing) is a much more stable and efficient speaker. This is thanks to redesigned speaker drivers, refactored audio-, and firmware routing, as well as the consolidation of two PCBAs into a single one. We have dedicated efforts to enhance sensitivity and reduce noise for XLR inputs ensuring a cleaner audio experience, and implemented a next-generation SKAA antenna with strategic placement, resulting in better TeamUp connection capability. Last but not least, SOUNDBOKS 4 gives your 20% longer playtime at maximum volume.


    The look of the SOUNDBOKS 4 has been tweaked with our newly designed hi-def snap-off grill that allows you to easily make it your own. On top of this, we’ve improved the LEDs in the UI panel for better visuals and changed the names of our in-app sound profiles to put emphasis on the completely re-engineered and vastly improved audio experience. On top of this the new naming is more intuitive, enabling you to quickly select a tailored sound setting for the specific use case.


Unleash Audio Mastery with the SOUNDBOKS App. Sculpt your sound using the equalizer or choose responsive profiles for the perfect note. Enhance precision, reinforce security, and upgrade effortlessly, ensuring peak performance.

How has the audio quality of the SOUNDBOKS 4 been improved?

Complete revamping of sound quality for more bass, better mids, and crisper highs.

How much longer is the battery life on the SOUNDBOKS 4 than the 3?

20% longer at full blast (~6 hours)

How has the grill design been changed on the SOUNDBOKS 4?
The new grill has smaller holes and an easy detach mechanism that allows you to pop it off, paint it, and pop it right back on. It now comes in both Metallic Grey and Black.

What is the usual playtime on a SOUNDBOKS 4?
The BATTERYBOKS in the SOUNDBOKS 4 (compatible with all SOUNDBOKS speakers) lasts for ~40 hours when playing music at mid-volume and ~6 hours at full volume depending on the amount of bass frequencies being played.

Do I need to use the SOUNDBOKS app with the SOUNDBOKS 4?

Nope, but we highly recommend doing so. With the app, you can use TeamUp to connect other SOUNDBOKS 4, 3, and Go speakers. Without the app, you won’t be able to access things like the sound and performance updates. You’ll also miss out on our advanced controls and EQ profiles. Plus you can’t use TeamUp to assign speaker roles, and that stuff is really cool.

What is an OTA and why should I care?

Over-The-Air Updates (OTA) via the SOUNDBOKS App help keep your SOUNDBOKS performing its absolute best, similar to updates on your other devices (phones, tablets, laptops). In addition to pumping out new features and content, our team is constantly working to improve the SOUNDBOKS experience through OTAs.

Do I need to register my SOUNDBOKS in the SOUNDBOKS app?

If you want an additional year of warranty (on top of the standard SOUNDBOKS 2-year warranty) or if you want access to the full world of SOUNDBOKS, additional speaker security, and all the other awesome features we’re currently developing, then you need to register. But if none of that matters to you, then feel free to enjoy your SOUNDBOKS as it is out-of-the-box.

Why does a Bluetooth speaker need to be durable?
We have no idea what your shindigs look like, but parties and events we like have historically been pretty unpredictable, so we designed the SOUNDBOKS to be ready for almost anything. Our internal components have an IP65 rating (that said, the Pulse Reflex Ports mean it really shouldn’t be fully submerged). The electronics and battery can play in temperatures from -10 to +40 °C (+14 to +104 °F).

Can I connect multiple SOUNDBOKS speakers wirelessly?
With TeamUp mode, absolutely. Using the amazing SKAA (pronounced like the musical genre) technology, your SOUNDBOKS can host up to 4 other Go, SOUNDBOKS 3, or SOUNDBOKS 4 speakers in Join mode. You can also Join any Go, SOUNDBOKS 3, or 4 speakers that are in Host mode.

Can I connect instruments and microphones to the SOUNDBOKS 4?
Yes! The SOUNDBOKS 4, like 3, includes the ProPanel with microphone (XLR) and mixer/instrument (TRS) inputs.
