Ultimate Ears WONDERBOOM 4 — Blue Portable Waterproof Bluetooth Speaker

Meet the Ultimate Ears WONDERBOOM 4, a compact yet mighty speaker built for life beyond the living room. This blue Wonderboom 4 packs a surprisingly powerful, immersive sound into a buoyant, rugged chassis that stands up to outdoor adventures, travel days, and everyday use with equal confidence. Its 360-degree sound fills spaces with clear highs, punchy mids, and a bass-forward boost that makes tracks feel lively and engaging, whether you’re by a pool, on a hiking trail, or hosting friends in the backyard. With a Bluetooth range of up to 131 feet (40 meters), you can wander freely without losing the connection to your device, letting you keep the party flowing while you move around. The Wonderboom 4 is designed to endure water, dust, and light impacts, and it even floats on water—so you can grab it easily from a pool or lake and keep the music going without interruption. Beyond durability and range, this speaker combines simple controls, versatile pairing options, and a vivid blue finish that stands out in your gear stack or backpack, making it the go-to companion for outdoor playlists, pool parties, and on-the-go listening.

• Immersive 360-degree sound with big bass: The WONDERBOOM 4 delivers a broad, enveloping sound field that fills rooms, patios, campsites, and beachside nooks with music you can feel as well as hear. Dual drivers and strategic bass radiators work together to produce rich, balanced audio across the spectrum, so even bass-heavy tracks stay tight and controlled. The 360-degree design ensures consistent audio coverage no matter where you’re positioned in relation to the speaker, making it ideal for social gatherings, picnics, and spontaneous dance breaks during outdoor adventures. With this setup, you won’t miss the thump of your favorite basslines, and the clarity on vocals and instrumentals remains intact at higher volumes, turning any space into a compact outdoor concert hall.
• Rugged, waterproof, and floating design: Built to survive the elements, the WONDERBOOM 4 features a robust, buoyant shell that resists splashes, dust, and minor bumps. It’s designed for outdoor use—from rainy hikes to beach days—without worrying about damage from moisture or dirt. A standout benefit is its ability to float on water, which makes it easy to locate in a pool or lake and reduces the risk of losing the speaker during water-based activities. The compact, pocketable form factor combined with a rugged exterior makes it a dependable companion for camping, boating, barbecues, or simply listening to tunes while you unwind outdoors.
• All-day battery life with convenient USB-C charging: The WONDERBOOM 4 emphasizes endurance so you can enjoy hours of listening without frequent recharges. The battery is designed to support extended outdoor sessions, travel days, and long playlists, while USB-C charging keeps recharging straightforward and quick. You’ll appreciate how quickly you can top up the battery between adventures, so the music never has to pause because of a low-charge warning. This long-lasting power paired with efficient energy management means you can keep the soundtrack going from sunup to sundown, through road trips or multi-day camping trips, without constantly babysitting a charger.
• Simple controls and versatile pairing: The intuitive control layout keeps music in reach with dedicated buttons for power, volume, and playback. You can easily adjust the volume on the speaker itself, skip tracks, or pause playback without pulling out your phone. For bigger, bolder sound, you can pair two WONDERBOOM 4 speakers or connect with other Ultimate Ears speakers to expand the soundstage, create stereo separation, or set up a multi-speaker array for a larger gathering. The straightforward design means you’ll spend less time fiddling with settings and more time enjoying your favorite playlists, podcasts, or audio from your favorite devices.
• Reliable Bluetooth performance with extended range: The speaker supports robust Bluetooth streaming with a generous range, allowing you to roam your space freely while staying connected. The 131-foot (40-meter) range translates to practical freedom in backyards, parks, and sizable rooms, so you can stay connected to your device for music, podcasts, or hands-free calls. Stable pairing and minimal dropouts are a hallmark of the Wonderboom 4’s wireless design, which is especially welcome when you’re entertaining guests, grilling outdoors, or enjoying an active day outside where cables would get in the way.
