Soundcore Boom 3i by Anker – The Ultimate Rugged Speaker for Outdoor Adventures

The Soundcore Boom 3i by Anker is not your average portable speaker—it’s a rugged, high-performance audio companion built to thrive in the wild. Whether you’re kayaking through rapids, hosting a beach party, or hiking remote trails, this speaker is engineered to deliver immersive sound, unmatched durability, and smart functionality in the most demanding environments. With features like industry-first floating playback, IP68 waterproofing, saltwater resistance, and BassUp 2.0 technology, the Boom 3i is designed to be the heartbeat of your outdoor lifestyle.

Industry-First Floating Playback – Music That Rides the Waves

One of the most revolutionary features of the Soundcore Boom 3i by Anker is its floating playback design. Unlike traditional speakers that tip, sink, or distort when exposed to water, the Boom 3i is engineered to stay upright and sound-forward, even when floating in waves. This means your music remains clear, powerful, and undistorted, whether you’re in a pool, lake, or ocean.

This feature is a game-changer for water-based activities. Imagine kayaking with your favorite playlist echoing across the water, or hosting a pool party where the speaker floats effortlessly, delivering crisp audio to every corner. The Boom 3i eliminates the fear of water damage or muffled sound, giving you confidence and freedom to take your music anywhere.

Its buoyant design is not just functional—it’s also stylish and compact, making it easy to toss into your gear bag and deploy whenever the moment calls for music.

IP68 Waterproof and Dustproof – Built to Brave the Elements

The Soundcore Boom 3i by Anker boasts an IP68 rating, which means it’s fully waterproof and dust-tight. This is the highest level of protection available for consumer electronics, ensuring that the speaker can be completely submerged in water without sustaining damage. Whether you’re caught in a sudden downpour, splashed by waves, or surrounded by sand, the Boom 3i keeps playing.

This level of protection makes it ideal for beach days, camping trips, fishing excursions, and muddy trails. You don’t have to worry about rain, spills, or debris—just press play and enjoy. The rugged casing is designed to withstand abrasion and impact, while the internal components are sealed to prevent moisture infiltration.

For adventurers who demand gear that performs under pressure, the Boom 3i is a reliable companion that won’t quit when the weather turns.

5x Saltwater-Resistant & Ultra-Durable – Engineered for Extremes

Saltwater is notoriously corrosive, but the Soundcore Boom 3i by Anker is built to resist it. With 5x the saltwater resistance of standard speakers, it’s protected against sea spray, sweat, and humidity, making it perfect for coastal environments and intense workouts.

This speaker has also been drop-tested from 3.28 feet (1 meter), proving its ability to withstand bumps, knocks, and rough handling. Whether it falls off a boat deck or gets tossed into a backpack, the Boom 3i maintains its integrity and performance.

Its reinforced housing and protective coating ensure that it remains rust-free and fully functional, even after repeated exposure to harsh conditions. For users who live life on the edge, the Boom 3i offers peace of mind and long-term durability.

Double the Bass with BassUp 2.0 – Feel the Power of 50W Sound

Audio performance is where the Soundcore Boom 3i by Anker truly shines. With 50 watts of output power, this speaker delivers room-filling sound that’s rich, dynamic, and deeply satisfying. The secret lies in BassUp 2.0 technology, which uses advanced Digital Signal Processing (DSP) to enhance low frequencies and deliver bass as deep as 56Hz.

Whether you’re playing hip-hop, rock, EDM, or acoustic tracks, the Boom 3i ensures that every beat is punchy and immersive. The dual passive radiators and high-efficiency drivers work together to produce crisp highs, balanced mids, and thunderous lows, creating a concert-like experience in a compact form.

Lab tests show that BassUp 2.0 delivers a 3dB increase in bass power within the voice frequency range (56Hz–20kHz), outperforming many competitors in its class. This makes the Boom 3i ideal for both casual listening and high-energy gatherings.

Smart Features and 16H Playtime – Built for All-Day Adventures

The Soundcore Boom 3i by Anker isn’t just about sound—it’s packed with smart features that enhance usability and convenience. With up to 16 hours of playtime on a single charge, you can enjoy nonstop music from sunrise to sunset. Whether you’re camping overnight or hosting a full-day event, the Boom 3i keeps the energy going.

The speaker pairs with the Soundcore app, allowing you to customize EQ settings, activate special modes, and monitor battery life. It also includes:

Voice Amplifier: Ideal for group announcements or karaoke sessions.
Emergency Alarm: A loud alert system for safety in remote areas.
Buzz Clean Technology: Self-cleaning audio that reduces distortion and maintains clarity over time.

A detachable strap makes it easy to carry or hang the speaker from a backpack, tent, or bike. These thoughtful additions make the Boom 3i a versatile tool for both entertainment and utility.

Voice Assistant and Speakerphone Functionality

While the Soundcore Boom 3i comes loaded with features to boost your experience, it does not include built-in voice assistant support like Alexa, Google Assistant, or Siri. Additionally, this speaker does not have a speakerphone function, so you won’t be able to take calls directly through the device. The focus here is on delivering robust sound and practical tools for outdoor adventures, ensuring your music and activities stay center stage without any distractions.

Bluetooth 5.3 Connectivity – Fast, Stable, and Efficient

Connectivity is seamless with the Soundcore Boom 3i by Anker, thanks to its Bluetooth 5.3 technology. This latest version of Bluetooth offers faster pairing, stronger signal stability, and lower power consumption, ensuring that your music streams smoothly without interruptions.

You can connect the speaker to your smartphone, tablet, or laptop in seconds, and enjoy lag-free audio even at extended distances. The Boom 3i also supports TWS (True Wireless Stereo) and PartyCast mode, allowing you to link multiple Soundcore speakers for a synchronized audio experience.

Whether you’re hosting a party or creating a surround sound setup at your campsite, Bluetooth 5.3 ensures that your connection is reliable and responsive.

Bluetooth Latency and Watching Videos – What to Expect

While the Boom 3i shines for music playback, its Bluetooth latency does bring some considerations if you’re planning to use it for watching videos. Due to the inherent lag over a wireless connection, you might notice that the audio doesn’t always sync perfectly with the on-screen action—especially during fast-paced scenes or dialogue-heavy content.

Some video apps and devices can automatically adjust to minimize these lip-sync delays, but results will vary depending on your setup. If you frequently stream movies, YouTube clips, or binge your favorite shows from your phone or tablet, keep in mind:

Audio-Video Sync: There may be a slight delay between what you see and hear, which is noticeable during dialogues or when sound effects need to match precise timing.
Room-Filling Sound: The Boom 3i provides crisp, clear audio, but its compact size means it’s better suited for smaller gatherings or cozy viewing sessions rather than replicating a home theater experience.
Stereo Playback: To experience true stereo separation with videos, you can pair two Boom 3i speakers together. On its own, the speaker mixes channels to mono, so spatial effects will be less pronounced.

In summary, while the Boom 3i is fantastic for wireless audio streaming and casual YouTube sessions, those who are sensitive to lip-sync accuracy or crave powerful cinematic impact may want to keep these factors in mind when using it for movie night.

No Wi-Fi Connectivity – Simplicity Over Complexity

The Soundcore Boom 3i focuses on delivering a hassle-free wireless experience through Bluetooth only, with no Wi-Fi support built in. This means there are no options for connecting through home networks, and features like Apple AirPlay and Google Chromecast are not available.

While you won’t find Wi-Fi streaming or smart home integration here, the Boom 3i keeps things straightforward—so setup is fast and you’re ready to play your music anywhere, without worrying about network compatibility.

Compact Design with Big Impact – Portable Yet Powerful

Despite its rugged build and powerful output, the Soundcore Boom 3i by Anker maintains a compact footprint. Measuring approximately 21 × 8.5 × 7.8 cm and weighing just 783 grams, it’s easy to carry, store, and deploy wherever you go.

The speaker’s design is both functional and stylish, with a matte finish that resists fingerprints and a form factor that fits comfortably in your hand or gear bag. LED indicators provide real-time feedback on battery status and connectivity, while tactile buttons offer intuitive control over playback and volume.

It’s the perfect balance of portability and performance, making it suitable for both spontaneous outings and planned adventures.

Built for the Wild – A Speaker That Matches Your Spirit

The Soundcore Boom 3i by Anker is more than just a speaker—it’s a reflection of your adventurous spirit. It’s built to float, resist saltwater, survive drops, and deliver powerful sound in any setting. Whether you’re kayaking through rapids, hiking rugged trails, or dancing under the stars, the Boom 3i is your audio companion for every journey.

Its combination of durability, smart features, and immersive sound makes it a standout choice for outdoor enthusiasts, travelers, and anyone who refuses to compromise on quality. With the Boom 3i, you don’t just hear your music—you live it.

While the Soundcore Boom 3i packs impressive specs for its size, there are a few quirks and omissions you’ll want to keep in mind.

Strap Clips: The small clips that secure the strap are easy to misplace, especially if you’re always on the move or tossing the speaker in a bag.
Feedback and Chimes: You get pleasant tactile feedback from the buttons and helpful chimes for pairing devices, but oddly, there are no sounds indicating when you disconnect, hit the volume limits, or toggle BassUp mode. Although RGB lights briefly flash for certain actions and the power LED blinks at volume limits, if you prefer your speaker lights off, you’ll lose that feedback entirely.
Sound Dynamics at Max Volume: Cranking up the volume will easily fill a small to mid-sized room, but audio quality takes a hit as the bass gets noticeably compressed. This means the low-end thump you expect from kick drums and basslines doesn’t quite pack the same punch, and overall, the sound may feel less dynamic at higher volumes.
Connectivity Gaps: For those who like to plug in the old-fashioned way, note that there’s no AUX input. The USB-C port is solely for charging—no wired audio playback here.
App Experience: The companion app shows charging status instead of a precise battery percentage, so you’ll be guessing how much playtime you have left. There’s no Party mode, either, so linking up with multiple speakers for a synchronized sound fest isn’t an option.
Latency Concerns: If you enjoy watching videos, be aware there can be some audio lag on both Android and iOS devices. The amount varies depending on your streaming app, but some lip-sync mismatch is possible.

All considered, the Boom 3i is a rugged, energetic companion for outdoor adventures, but if you prioritize top-tier audio fidelity at maximum volume, extensive connectivity, or advanced app features, you might need to look at larger or more feature-heavy models.

Soundcore Boom 3i vs. Ultimate Ears BOOM 4 – Which One Rules the Outdoors?

When it comes to choosing a Bluetooth speaker for your next adventure, two contenders often rise to the top: the Soundcore Boom 3i by Anker and the Ultimate Ears BOOM 4. Both are purpose-built for active lifestyles, but each brings its own unique strengths to the campsite, beach, or backyard barbecue.

Outdoor Performance and Water Readiness

If you’re the type who relishes riverside picnics or paddleboarding with playlists, the Boom 3i clearly steps up to the plate. Thanks to its advanced saltwater resistance and floating design, this speaker doesn’t just shrug off occasional splashes—it’s fully at home above (and in) the water. The clever placement of its rotating drivers ensures your tunes keep playing loud and clear, even if the whole speaker is bobbing in the surf.

The Ultimate Ears BOOM 4, on the other hand, prides itself on immersive 360-degree sound. This means you can plunk it down in the middle of a circle, and everyone gets the full audio experience, no matter where they sit. It’s a party trick that works well at picnics or parks, although water-specific features take a slight back seat compared to the Boom 3i’s amphibious DNA.

Sound Customization and Connectivity

Both speakers offer plenty of scope for personalizing your sound through their respective companion apps, putting you in charge of your audio experience—bass thumping jungle trek or mellow indie campfire session, it’s your call.

Where they diverge is in how they connect with friends’ devices and extra speakers. The Ultimate Ears model makes group listening a breeze by syncing up with other Ultimate Ears units in its Party mode—a favorite for big gatherings. Meanwhile, the Boom 3i favors versatility with its stereo playback through TWS linking, perfect if you crave richer, directional audio.

Which Is Right for You?

Choose the Soundcore Boom 3i if you want a speaker that thrives around water, can withstand a salty splash, and keeps the music facing up—no matter where your adventures take you.
Opt for the Ultimate Ears BOOM 4 if you love all-around sound and want an excellent party speaker for group settings on solid ground.

In other words, if your weekends involve beaches, boats, or trailblazing through untamed wilds, the Boom 3i is the unbeatable companion. For laid-back days at the park or backyard socializing, the BOOM 4’s crowd-pleasing sound takes center stage. Either way, both keep the good times rolling long after sunset.

Soundcore Boom 3i vs. JBL Flip 7 – How Do They Compare?

When weighing your options between the Soundcore Boom 3i by Anker and the JBL Flip 7, you’ll find plenty of common ground—and a few key distinctions that could sway your decision.

Similarities:

Companion Apps: Each model is paired with a robust app, letting you tweak EQ settings, update firmware, and personalize your soundscape for any adventure.
Customizable Listening: Tailor your music experience with various sound presets and pairing options, whether you’re at a backyard gathering or deep in the wild.

Differences That Matter:

Water & Sand Readiness: This is where the Boom 3i truly shines. Its floating design means it won’t vanish beneath lake waves or pool ripples; plus, the upward-facing drivers ensure your music is never muffled. A unique Buzz Clean mode helps shake out stubborn sand—making it a real beach buddy.
Party Connectivity: The JBL Flip 7 steps up with Auracast support, making it easy to connect multiple JBL speakers across a space for massive, synchronized sound. Great if you already own other JBL models and want your playlist reverberating wall-to-wall.
Battery Life: The Boom 3i edges ahead here, boasting longer playtime—ideal for those multi-day outings or marathon parties under the open sky.

In short, if your journeys tend to involve water, sand, or long hours off the grid, the Boom 3i makes a compelling case. For those looking to build a massive mesh of party speakers with existing JBL gear, the Flip 7 keeps things seamless. Both are strong contenders, but the Boom 3i’s blend of adventure-ready features and extended battery life makes it our top pick for the untamed outdoors.
