Life has a soundtrack, and for me, that soundtrack often needed a significant upgrade, especially when I was away from home. I used to struggle with the tinny, underwhelming sound from my phone, trying to share music with friends at picnics or attempting to liven up a quiet evening by the pool. The idea of a truly portable, high-quality audio solution seemed like a distant dream, yet the need was undeniable. Without a proper speaker, every outdoor gathering felt a bit flat, and the joy of spontaneous music moments was often lost, leaving me with the frustration of subpar audio quality in situations that deserved more vibrant sound. A robust and versatile portable waterproof Bluetooth speaker would have been a game-changer.
Key Considerations for Your Next Portable Speaker
Before diving into a specific product, it’s crucial to understand why someone might be in the market for a portable speaker and what factors should guide their decision. Portable speakers, at their core, address the universal desire for music on the go, transforming mundane environments into vibrant soundscapes. They solve the problem of limited device audio, allowing you to amplify your favourite tunes, podcasts, or audiobooks wherever you are, without being tethered to power outlets or bulky setups. The ideal customer for such a device is someone active and social, who loves spending time outdoors – think beachgoers, campers, hikers, gardeners, or even just someone who enjoys music in the shower or by the pool. They value convenience, durability, and a decent sound experience that can withstand the elements.
However, not everyone needs this specific type of speaker. If your primary listening is done indoors, in a controlled environment, and you prioritise absolute audiophile-grade sound quality with intricate soundstages and deep, resonant bass, a dedicated home audio system or a larger, less portable speaker might be a better fit. Similarly, if you primarily use your speaker for quiet, personal listening and budget is an extreme constraint, there are simpler, cheaper options, though they might compromise on durability and sound. When considering a portable speaker, potential buyers should think about:
* Sound Quality: Is it clear, balanced, and loud enough for your intended use?
* Portability: How compact and lightweight is it? Does it have a loop or clip?
* Durability: Is it waterproof, dustproof, and shockproof? What IP rating does it have?
* Battery Life: How long will it last on a single charge?
* Connectivity: Is Bluetooth reliable? Are there other input options?
* Special Features: Does it offer 360-degree sound, stereo pairing, or outdoor modes?
* Value for Money: Does its performance justify its price point compared to alternatives?
Introducing the Ultimate Ears WONDERBOOM 4
Stepping into the spotlight is the Ultimate Ears Wonderboom 4 Portable Waterproof Bluetooth Speaker, a compact yet powerful device that promises surprisingly bigger 360-degree sound. This speaker is designed to be your go-anywhere audio companion, built for adventure with its robust construction and impressive environmental resilience. When you purchase this speaker, you typically receive the unit itself, a quick start guide (often printed inside the box), a convenient strap (already attached), and a USB-C charging cable.
Compared to its predecessors, the Wonderboom 4 refines the already popular formula, notably by upgrading to USB-C charging – a welcome change for many users who found the older micro-USB restrictive. While Ultimate Ears has always been a strong contender in the portable speaker market, often battling giants like JBL in terms of brand recognition, the Wonderboom series carved its niche with its distinctive spherical design and 360-degree audio. This particular WONDERBOOM 4 is ideal for those who need a speaker that can genuinely keep up with an active lifestyle: someone who frequently finds themselves by the pool, at the beach, in the shower, or on outdoor excursions. Its floatable design means it’s perfect for water-based activities. It might not be the best choice for audiophiles seeking deep, rumbling bass or sophisticated custom EQ options for indoor, critical listening, as its strength lies more in its rugged portability and robust outdoor performance.
Here’s a quick rundown of its primary strengths and weaknesses:
Pros:
* Exceptional Durability: IP67 waterproof, dustproof, floatable, and drop-proof from 1.5m.
* Impressive Portability: Compact size, lightweight, and features a handy loop for attachment.
* 360-Degree Sound: Delivers consistent audio experience from all angles.
* Long Battery Life: Up to 14 hours of playtime on a single charge.
* Convenient Pairing: Easy Bluetooth connection, Google Fast Pair, and “Double Up” for stereo sound with a second speaker.
Cons:
* Limited Bass Response: While it offers “big bass” for its size, some users might find the bass less impactful than larger competitors.
* No Dedicated App Control: Lacks a companion app for custom EQ settings, which can be a significant drawback for some users.
* Sound Quality vs. Price: A few users feel the sound quality, particularly the bass, doesn’t quite match its price point compared to some rivals.
* Outdoor-Optimised Sound: While a pro for outdoor use, its sound profile might be less appealing for indoor listening.
Unpacking the Core Features and Their Advantages
Having spent considerable time with the Ultimate Ears Wonderboom 4, I can attest to its robust design and thoughtful features, which truly make it stand out in the crowded portable speaker market. It’s not just about playing music; it’s about enabling a soundtrack for every adventure.
Surprisingly Bigger 360-Degree Sound
One of the headline features of the Wonderboom 4 is its claim of “surprisingly bigger 360-degree sound” in a petite package. And it genuinely delivers. When I first fired it up, I was genuinely impressed by how much sound came out of such a compact device. The 360-degree audio is a massive benefit, especially for group settings. Unlike speakers that project sound in one direction, the Wonderboom 4 fills an entire space with music. This means no one is stuck with a muffled experience, regardless of where they’re sitting around the speaker. Whether it’s placed in the centre of a picnic blanket or hanging from a tree branch, the sound disperses evenly, creating an immersive listening experience that genuinely enhances social gatherings. The sound profile is generally balanced, with clear mids and highs, ensuring vocals and instruments are distinct. While it might not rattle your windows with bass, for its size, the low end is certainly present and punchy enough to give music a satisfying depth, especially outdoors.
Outdoor Boost and Podcast Mode
Ultimate Ears has engineered this floating speaker with specific listening environments in mind, which is where Outdoor Boost and Podcast Mode come into play. The Outdoor Boost button is a game-changer for alfresco listening. In an outdoor environment, sound tends to dissipate rapidly, losing its impact. With a simple tap, Outdoor Boost kicks in, optimising the audio to cut through ambient noise and project further. This isn’t just a volume increase; it’s a specific EQ adjustment that enhances clarity and presence, making music sound much more vibrant and engaging even when there’s wind or other background noise. I’ve used this feature countless times at barbecues and while gardening, and it makes a noticeable difference.
Equally useful, the new Podcast Mode is a thoughtful addition. While other speakers might struggle with dialogue, making voices sound muddy or indistinct, Podcast Mode on the Ultimate Ears Wonderboom 4 makes vocals sound rich and clear. This is perfect for listening to spoken-word content, ensuring that every word of your favourite podcast or audiobook is crisp and easy to follow, even in a moderately noisy environment. It elevates the utility of the speaker beyond just music, catering to a broader range of audio consumption.
14 Hours of Boom
Battery life is paramount for any portable device, and the Wonderboom 4 doesn’t disappoint here. With up to 14 hours of playtime, this speaker truly lasts throughout the day and well into the evening. This extended battery life means you can take it on long hikes, spend an entire day at the beach, or power multiple social gatherings without constantly worrying about finding a power outlet. It offers peace of mind and genuine freedom, allowing you to soak up every moment without interruption. The upgrade to USB-C charging is also a significant convenience, meaning you can use the same charger as most of your other modern devices, reducing cable clutter.
Waterproof, Dustproof, and Floatable
This is where the dustproof speaker truly lives up to its “go-anywhere” promise. Boasting an IP67 rating, the Wonderboom 4 is built for the elements. Being IP67-rated means it can be submerged in up to 1 metre of water for 30 minutes and is completely protected from dust ingress. I’ve personally put this to the test, taking it to the pool, having it splashed repeatedly, and even letting it float serenely while I swim. It just keeps on playing without missing a beat. This feature isn’t just a gimmick; it removes all apprehension about using the speaker in wet or dirty environments. Shower concerts, beach parties, riverside picnics – this speaker is perfectly at home in all of them. Its floatable nature is particularly fun for pool parties, where it can drift alongside you, delivering tunes directly from the water.
Double Up for Stereo
For those moments when you want an even grander sound experience, the “Double Up” feature is incredibly useful. You can easily pair two Ultimate Ears Wonderboom 4 portable Bluetooth speakers together. A single press doubles the sound, amplifying the party, while pressing again activates true stereo sound, separating the left and right audio channels between the two speakers. This creates a much wider soundstage and a more immersive listening experience, especially for music. It’s perfect for larger spaces or when you want to fill a room with truly rich, directional sound. I’ve found this great for movie nights outdoors with a projector or for creating a more enveloping atmosphere at bigger gatherings.
Durable Wireless Speaker With Range
Beyond its water and dust resistance, the Ultimate Ears Wonderboom 4 is built to endure. It’s dirt-resistant and drop-proof, tested from 1.5 metres (5 feet). This robustness, combined with its compact, almost spherical design, makes it remarkably resilient to the knocks and bumps of everyday life and adventurous excursions. The handy loop attached to the speaker is a simple but brilliant addition, allowing you to easily clip it to a backpack, hang it from a branch, or even attach it to a bike. This significantly enhances its portability and ensures your music can always accompany you.
Furthermore, its wireless range is impressive, offering up to 40 metres (131 feet) of Bluetooth connectivity. This extensive range means you don’t have to keep your phone right next to the speaker. You’re free to roam, keep your device safely tucked away, and still maintain a strong, uninterrupted connection. I’ve appreciated this freedom when moving around a garden or a campsite, controlling music without having to be tethered. The inclusion of Google Fast Pair also streamlines the initial setup process for Android users, making connecting swift and effortless.
Made With Recycled Plastic
In an age where environmental responsibility is increasingly important, it’s heartening to see that the Wonderboom 4 incorporates sustainability into its design. The plastic parts of this wireless Bluetooth speaker include a minimum of 31% post-consumer recycled plastic by weight. This demonstrates a commitment from Ultimate Ears to reducing its environmental footprint, giving consumers a choice that aligns with their values without compromising on performance or durability. It’s a small but significant detail that adds to the overall appeal of the product.
What Other Users Are Saying
Having scoured the internet for real-world feedback, it’s clear that the Ultimate Ears Wonderboom 4 largely receives positive remarks, albeit with a few consistent points of criticism. Many users laud its incredible sound for its compact size, praising its clarity and impressive volume, even when acknowledging that the bass isn’t earth-shattering. The durable, waterproof, and floatable design is consistently highlighted as a major selling point, making it perfect for outdoor adventures and pool use. The convenience of USB-C charging, an upgrade from previous models, is also a frequently celebrated improvement. However, some users expressed disappointment over the lack of a companion app for customisable EQ settings, feeling that this limits the audio customisation. A few also noted that while the sound is great for its size and use case, those seeking truly deep, resonant bass might find it somewhat lacking when compared to certain larger or more expensive rivals, suggesting it’s best for portability over raw sonic power.
Final Thoughts and Recommendations
In conclusion, if you’re like me and constantly found yourself wishing for better sound, particularly in outdoor or active settings, the frustration of tinny phone speakers or fragile audio devices is very real. The complications of not having a robust, high-quality Bluetooth speaker mean sacrificing enjoyment, compromising on atmosphere, and potentially damaging less-durable equipment.
The Ultimate Ears Wonderboom 4 Portable Waterproof Bluetooth Speaker is an excellent fit to solve these problems for several compelling reasons. Firstly, its unparalleled durability – being waterproof, dustproof, floatable, and drop-proof – means it can truly go wherever you do without a second thought. Secondly, the surprisingly big 360-degree sound, coupled with Outdoor Boost and Podcast Mode, ensures your audio experience is optimised for any environment, from lively parties to focused listening. Finally, with 14 hours of battery life and convenient USB-C charging, it offers reliable, all-day performance, letting you focus on the moment, not the battery indicator. For a speaker that’s built for adventure and delivers great sound, you’d be hard-pressed to find a better companion. Click here to check the product out and elevate your audio experience!
