I remember it vividly. A perfect summer afternoon at the lake, friends gathered on the dock, the sun just starting to dip below the trees. The only thing missing was a decent soundtrack. My friend had brought a small, cheap Bluetooth speaker that sounded tinny and distant just a few feet away. Every time a boat went by, its sound was completely drowned out. The music, meant to be the heart of our gathering, became a frustrating, barely-audible whisper. It was a classic case of the right moment being let down by the wrong gear. This search for a speaker that doesn’t just play music, but truly enhances an experience—be it a rowdy beach party, a quiet camping trip, or a backyard barbecue—is what leads many of us down the rabbit hole of portable audio. We need something loud, clear, and tough enough to handle whatever life throws at it.

What to Consider Before Buying a Portable Bluetooth Speaker
A Portable Bluetooth Speaker is more than just an item; it’s a key solution for bringing high-quality audio wherever you go, untethered by wires or the need for a power outlet. It transforms a personal listening experience on your phone into a shared event, capable of filling a room, a campsite, or a poolside patio with rich sound. The primary benefit is freedom—the freedom to have your favorite playlists, podcasts, or audiobooks provide the backdrop to your life’s most memorable moments. Without a capable speaker, you’re often left with the inadequate sound from a smartphone, which lacks the volume, bass, and clarity to be enjoyed by more than one person in any environment with even a little ambient noise.
The ideal customer for this type of product is someone with an active or social lifestyle. Think of the weekend adventurer, the college student who moves between their dorm and the quad, the family that spends summers by the pool, or the remote worker who wants to fill their home office with music without a complex stereo system. It’s for those who value durability, portability, and powerful sound in one package. Conversely, this might not be the right choice for a dedicated home audiophile who prioritizes stationary, wired systems with lossless audio fidelity and channel separation above all else. For them, a traditional bookshelf or tower speaker system would be a better investment. The Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker is designed to fill that critical gap between portability and performance.
Before investing, consider these crucial points in detail:
- Dimensions & Portability: How portable is “portable” for you? A speaker’s size and weight directly impact where you can take it. Cylindrical designs like the MEGABOOM 4 often fit in backpack water bottle pockets or even a bike cage, as one user noted. Consider if you need something pocket-sized or if you have the space for a larger unit that typically delivers bigger sound.
- Audio Performance & Battery Life: This is the heart of the matter. Look for specs like driver size, power output (watts), and frequency response, but also trust real-world testing. Does it offer 360-degree sound for group listening? How is the bass response? Battery life is equally critical; a 20-hour rating, like the MEGABOOM 4’s, means you can likely get through a full weekend getaway without needing a recharge.
- Materials & Durability: Your speaker should be ready for your life. An IP (Ingress Protection) rating is key. IP67, for instance, means the device is completely dustproof and can be submerged in up to 1 meter of water for 30 minutes. Look for rugged materials, shockproof ratings, and features like floating, which can be a lifesaver near pools or lakes.
- Ease of Use & Connectivity: A speaker should be simple to operate. Check for intuitive physical controls, a stable Bluetooth connection with a long range (the MEGABOOM 4 boasts an impressive 147ft), and any companion apps. A good app can unlock features like a customizable EQ, speaker pairing (like UE’s PartyUp), and firmware updates, significantly enhancing the long-term value of your device.
Considering these factors will ensure you choose a speaker that not only sounds great but also seamlessly integrates into your lifestyle.

First Impressions: Built Like a Premium Tank
Unboxing the Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker is a satisfyingly minimalist experience. The speaker is front and center, feeling immediately substantial and well-crafted in the hand. The signature acoustic fabric is tightly woven and feels both durable and premium, while the thick rubber spine and end caps inspire confidence. At 1.23 kg (about 2.7 lbs), it has a reassuring heft without being overly burdensome. It’s a device that feels like it was engineered, not just manufactured. The iconic, oversized plus and minus volume buttons are not just a design statement; they are incredibly practical, allowing you to adjust volume by feel without ever looking at the speaker. Setting it up was a breeze—a simple press of the power button, a quick Bluetooth pair with my phone, and I was playing music in under a minute. There’s no assembly, just pure plug-and-play (or rather, pair-and-play) functionality. Compared to its predecessor, the MEGABOOM 3, the design is refined, not reinvented, which is a good thing. It retains the classic cylindrical form factor that has made this line so popular. You can check the latest price and available colors here.

Performance Deep Dive: Sound, Strength, and Smarts
A speaker’s worth is measured in three key areas: how it sounds, how it holds up, and how easy it is to live with. We pushed the Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker to its limits in all three categories to see if the real-world performance lives up to the impressive spec sheet. The results were largely fantastic, with a few important caveats to consider.
The 360-Degree Soundscape: Power, Clarity, and a Bass Conundrum
The headline feature of the MEGABOOM line has always been its 360-degree sound projection, and the version 4 continues this tradition beautifully. Placing the speaker in the center of a room or outdoor patio creates a remarkably consistent listening experience for everyone, eliminating the “sweet spot” problem that plagues directional speakers. The sound profile is bold, energetic, and loud. We found it more than capable of powering a backyard party, with one user confirming, “I use it at work and everyone can hear it, it’s absolutely worth the money.” The clarity in the mid-range and highs is commendable, allowing vocals and instruments in rock, pop, and electronic music to shine through with presence and detail.
However, the “Thundering Bass” claim is where things get complicated. At low to medium volumes (up to about 75%), the bass is punchy, deep, and satisfying, providing a solid foundation for the music. But as we pushed the volume towards its maximum, we began to notice the same issue some users have reported. One critical user stated, “The bass kills the sound. It is very distorted and causes distortion on the treble side even a low volume and gets worse the higher the volume.” We found this to be most pronounced on bass-heavy tracks. It seems that in the quest for loudness, the digital signal processing (DSP) can push the woofers a bit too hard, sacrificing clarity for raw power. Thankfully, this is where the UE app becomes an essential tool. The app’s customizable EQ allows you to tame the low end. As another user wisely advised, “I just recommend being careful with the EQ, and volume, at moderately high volume or above.” By slightly reducing the bass and boosting the mids in the app’s equalizer, we were able to achieve a much cleaner, more balanced sound at higher volumes. While it shouldn’t be necessary to tweak a speaker out of the box, the option to do so provides a crucial workaround for this model’s most significant audio flaw. For those who prioritize balanced audio, the customizable EQ is a feature that truly saves the experience.
Built for Adventure: Unpacking the “Waterproof, Drop-Proof, Dust-Proof” Promise
This is where the Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker unequivocally excels and justifies its premium positioning. The build quality isn’t just for show; it’s a core part of its identity. We took it to the pool, and true to its word, it floats. Not only does this prevent it from sinking to a watery grave, but it also continues to play music clearly while bobbing on the surface. We knocked it off a picnic table onto the grass, and it didn’t skip a beat. We even (for the sake of a thorough review) submerged it in a bucket of water for several minutes, and it emerged working perfectly. The IP67 rating is no joke. One user shared an incredible story of durability: their first UE speaker “melted in a house fire, but still worked.” While we don’t recommend testing that claim, it speaks volumes about the product’s resilience.
This ruggedness transforms how you think about using a piece of electronics. You stop worrying about it. Spilled drinks, sudden rain showers, a sandy beach day, or a clumsy guest are no longer threats. As one happy owner put it, “I love the features of it being dust proof, waterproof, and drop proof! I like how you can be rough with it and it still works great! It also gives you the confidence that you really can bring it anywhere with you!” We found this to be true in our testing. We brought it into the bathroom during a steamy shower, just as another user mentioned, and it performed flawlessly. This go-anywhere, do-anything attitude is the speaker’s greatest strength and a primary reason to choose it over more delicate competitors. It is, without a doubt, one of the most durable portable speakers we have ever tested.
Beyond the Speaker: Battery, Connectivity, and the Magic Button
A portable speaker’s brilliance fades quickly if it’s constantly dead or losing connection. The Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker delivers strongly on these practical fronts. The 20-hour battery claim held up remarkably well in our tests. Over a weekend of intermittent use at moderate volumes, we never had to reach for the charger. One user even joked, “I haven’t charged it, in more than a week.” This longevity is a massive quality-of-life improvement, freeing you from battery anxiety during extended outings. The Bluetooth 5.0 connection is rock-solid. The advertised 147-foot (45-meter) range is genuinely impressive. We were able to leave the speaker in the backyard and walk all the way to the front of the house with our phone without a single dropout. As one reviewer confirmed, “I walked 50 feet away and it worked perfectly fine. I don’t think I’d have a need to walk away 147 feet.” This massive range means the music doesn’t stop just because the person with the connected phone needs to grab something from their car or walk inside.
The “Magic Button” on top is another clever feature, though its utility depends on your music service. It offers one-touch play, pause, and skip controls without needing to touch your phone. The real magic, however, is the long-press function, which can be programmed in the app to launch a specific playlist from services like Spotify or Apple Music. It’s a genuinely useful shortcut for firing up your favorite tunes instantly. The app also enables “PartyUp,” allowing you to sync your MEGABOOM 4 with dozens—even hundreds—of other UE BOOM and MEGABOOM speakers. While we only tested it with two speakers, the stereo pairing worked seamlessly, creating a much more immersive and powerful soundstage. These smart features elevate the MEGABOOM 4 from a simple speaker to a more integrated and convenient audio ecosystem, and you can see its full feature set and user reviews to learn more.
What Other Users Are Saying
Digging through feedback from other owners reveals a clear, albeit divided, consensus. The vast majority of users are thrilled with their purchase, particularly those who prioritize durability and volume. One enthusiastic husband “loves it” and says “this is his favorite by far. The sound is amazing!!!” Another user echoes this, stating, “I am beyond impressed with the Megaboom 4! I really love the sleek design, and the fact that it is portable.” These reviews consistently praise the speaker’s rugged, go-anywhere nature and its ability to fill large spaces with sound.
However, a vocal minority expresses significant disappointment with the audio quality, specifically the bass. One of the most critical reviews we saw warned, “Do not get this speaker! The audio quality is horrible… The bass kills the sound.” This sentiment was shared by another who felt it was a downgrade from the MEGABOOM 3 and that a “10 year old Samsung little one and has better bass.” This stark contrast in opinion seems to hinge on musical taste and volume levels. For those who listen to bass-heavy music at maximum volume, the DSP’s aggressive tuning can lead to distortion. For others listening to a wider variety of genres at more moderate levels, the sound is perceived as powerful and impressive. This feedback is critical: it suggests that while the speaker is an incredible all-around performer, it may not satisfy audiophiles looking for pristine, distortion-free bass at peak volumes.
How Does the Ultimate Ears MEGABOOM 4 Compare to Alternatives?
The Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker sits in a competitive market. While it excels in durability and 360-degree sound, other options might be a better fit depending on your budget and specific needs.
1. Passau Portable Bluetooth Speaker Loud 40W RGB
- 40 Watts Bass Boost: Get powerful stereo sound with 2 full-range drivers in portable speaker bluetooth, dual passive radiators pumps out enhanced bass, strong mid, and crystal clear high sound without...
- TWS Pair & Bluetooth 5.3: Easily TWS pair two loud speakers bluetooth wireless at the same time to truly enjoy the unparalleled sound quality, perfect big speaker for playing games, listening to music...
The Passau speaker is a clear budget-friendly alternative for someone whose top priority is party atmosphere over ruggedness. Its main draws are the built-in RGB lights that sync with the music and its significantly lower price point. While it boasts a 40W peak output, its audio fidelity and build quality are not in the same league as the MEGABOOM 4. It has only an IPX5 rating, meaning it can handle splashes but cannot be submerged. If you’re looking for a fun, flashy speaker for occasional indoor or sheltered outdoor use and want to save a considerable amount of money, the Passau is a compelling choice. However, for serious outdoor adventures, the MEGABOOM 4’s superior waterproofing and durability are well worth the extra investment.
2. DOSS SoundBox Pro Bluetooth Speaker 20W Waterproof
- Powerful Stereo Sound: Experience 20W of immersive stereo sound with dual full-range drivers and dual passive radiators, delivering enhanced bass, tight mids, and crystal-clear highs—all without...
- Active Extra Bass: Simply press the Extra Bass button to instantly boost bass and volume. Feel the deep, punchy beats perfect for hip-hop dance, or bring your music to life with this bass Bluetooth...
The DOSS SoundBox Pro is a popular mid-range competitor that focuses heavily on bass performance with its “Active Extra Bass” feature. Like the Passau, it includes party lights and comes in at a much more accessible price than the MEGABOOM 4. Its IPX6 rating is a step up, protecting it from powerful jets of water, but it still falls short of the MEGABOOM 4’s fully waterproof and dustproof IP67 rating. The SoundBox Pro is an excellent choice for users who want strong bass and party features without the premium cost and extreme durability of the UE speaker. It’s a great middle-ground option, but if your speaker is destined for the poolside, beach, or canoe, the MEGABOOM 4’s ability to be fully submerged offers invaluable peace of mind.
3. ASEAT Bluetooth Speaker Cell Phone Stand
- 【Phone Stand & Bluetooth Speaker】- ASEAT Cell Phone Holder with wireless speaker is made of high quality loudspeaker and BLUETOOTH V5.3 which perfectly realize enhanced bass, accurate mids and...
- 【LED Color Changing Atmosphere Lights】- The phone stand not only frees your hand when using phone or tablet, but can be a colorful atmosphere light. Mellow music and lighting helped to create the...
The ASEAT device is less a direct competitor and more of a multi-function gadget. Its primary function is a cell phone stand, with a Bluetooth speaker and LED light added as secondary features. It is designed for a desk, nightstand, or kitchen counter, not for a hiking trail or beach party. Its audio performance and durability are not intended to compete with dedicated portable speakers like the MEGABOOM 4. Someone might prefer this product if they’re looking for a unique, cool tech gadget or a gift that combines several functions in one small package for stationary use. For anyone seeking powerful, portable, high-quality audio for an active lifestyle, the Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker is in a completely different—and far superior—category.
Final Verdict: An Adventurer’s Perfect Audio Companion
After extensive testing and analysis, our verdict on the Ultimate Ears MEGABOOM 4 Waterproof Bluetooth Speaker is overwhelmingly positive, with a key recommendation. This is an exceptional speaker for its intended audience: the active, adventurous, and social user who needs a device that can keep up with their lifestyle. Its class-leading durability, incredible battery life, and powerful, room-filling 360-degree sound make it the perfect companion for everything from a rugged camping trip to a lively pool party. The confidence that comes from knowing it can be dropped, soaked, or covered in dust without issue cannot be overstated.
The only significant hesitation comes from the bass performance at maximum volume. For users who prioritize pristine audio fidelity above all else, the potential for distortion on bass-heavy tracks might be a dealbreaker. However, for the vast majority of listeners, this can be easily managed with the app’s EQ. If you’re looking for a portable speaker that is built like a tank, sounds huge, and has the battery to last for days, the MEGABOOM 4 is one of the best choices on the market. It is a premium product with a premium price, but it delivers an experience and a level of durability that justifies the cost. If you’re ready to invest in a soundtrack for your adventures that won’t let you down, we highly recommend you check the latest price and get your Ultimate Ears MEGABOOM 4 today.
