Sized between standard travel cylinders and oversized party boxes, it targets campers, beachgoers, and backyard entertainers who want robust volume and rich acoustics without sacrificing field-ready durability. Built around high-impact recycled materials and covered in tough ballistic weave, it handles drops, dirt, and heavy splashes with ease.
In real-world testing, the EVERBOOM proves remarkably user-friendly. An impressive 180-foot Bluetooth range ensures that your phone stays connected while you move freely around a campsite or pool deck.

Acoustically, the EVERBOOM relies on a 360-degree driver orientation designed to radiate audio uniformly, eliminating directional dead zones.

Midrange frequencies remain articulate and forward, allowing dialogue in podcasts and vocal tracks to cut through clearly rather than becoming buried beneath low-end rumble.
When stepping into wide-open environments, the Outdoor Boost feature demonstrates its engineering value. Tapping the boost button adjusts the speaker's EQ curve to emphasize upper midrange and high-frequency projection, ensuring audio intelligibility against waves, wind, and active group chatter. Digital signal processing keeps distortion minimal even at higher outputs, resulting in a cohesive, energetic presentation suitable for any gathering.

Backed by a certified IP67 rating, this speaker is fully dustproof, sandproof, and submersible in up to one meter of water for 30 minutes, with the added benefit of natural buoyancy that keeps it floating on the water's surface.
Under the hood, an internal lithium-ion battery provides up to 20 hours of continuous playback, conveniently recharged via standard USB-C. Wireless communication is handled by long-range Bluetooth paired with fast-tap NFC on the top surface. For those looking to expand their sound, the integrated PartyUp architecture enables wireless synchronization with all modern BOOM, MEGABOOM, EPICBOOM, and HYPERBOOM speakers to create a cohesive multi-speaker setup.
