Ultimate Ears Boom 3 Portable Waterproof Bluetooth Speaker Review



The Ultimate Ears Boom 3 stands as a beacon of innovation and design in the saturated market of portable Bluetooth speakers. Crafted for audiophiles who seek adventure and quality in equal measure, this speaker is an amalgamation of robust features, aesthetic appeal, and immersive sound quality. With an impressive lineage stemming from Ultimate Ears, a brand renowned for its professional audio equipment, the Boom 3 is not just an ordinary speaker – it’s a testament to what portable sound systems can achieve.

Firstly, the Ultimate Ears Boom 3 boasts an iconic cylindrical design, making it not only visually appealing but also facilitating a 360-degree sound dispersion. This means, no matter where you are around the speaker, you will experience the same intensity and clarity of music. Such thoughtful design is complemented by a variety of vibrant colors and high-performance fabric, making the Boom 3 a stylish accessory for any setting.

However, aesthetics aside, where the Boom 3 truly shines is in its performance. Equipped with a magic button, it allows users to play, pause, and skip tracks directly on the speaker, offering utmost convenience. The device is powered by a battery that promises up to 15 hours of uninterrupted musical euphoria, ensuring that your parties go on till dawn.

Durability is another cornerstone of the Boom 3’s design. It’s not just waterproof; it’s capable of surviving dips in the pool, thanks to its IP67 water and dustproof rating. This makes it an ideal companion for beach outings, pool parties, or even those unpredictable rainy days. Moreover, the speaker floats, a feature that not only protects it from sinking but also adds a fun element to its usability.

When it comes to sound, the Boom 3 doesn’t hold back. It delivers balanced and rich audio, with a special emphasis on clarity and depth. The bass is deep and punchy, ensuring that every beat of the music is felt. It’s also worth noting that the speaker is incredibly loud, making it perfect for outdoor settings.

Design and Build Quality

The Ultimate Ears Boom 3 commands attention with its iconic cylindrical design, which isn’t just about aesthetics but functionality as well. The speaker’s uniform shape contributes to its 360-degree sound output, ensuring a uniform audio experience from all angles. Covered with a two-tone fabric that’s tough and beautiful, the Boom 3 is engineered to withstand the rigors of adventurous use. From accidental drops to sudden showers, this speaker is ready for anything, thanks to its IP67 water and dustproof rating. The integration of a hanging loop adds to its portability, allowing users to hook it onto a backpack or hang it in a tent easily.

Sound Quality and Performance

Ultimate Ears has a reputation for excellent sound, and the Boom 3 lives up to that legacy. It offers a balanced sound profile with an emphasis on clarity and depth. The mids and highs are crisp and clear, allowing vocals and instruments to shine. The bass, though not overwhelming, provides enough punch to keep the beat going. It’s particularly commendable how the Boom 3 maintains sound integrity at higher volumes, with minimal distortion. The magic button on top of the speaker adds a layer of convenience, enabling quick control over playback without reaching for your phone.

Battery Life and Connectivity

The Ultimate Ears Boom 3 is designed for prolonged use with up to 15 hours of battery life on a single charge. This endurance makes it a reliable partner for long outdoor trips or all-night parties. Recharging is hassle-free with the optional charging dock or standard micro USB. On the connectivity front, the Boom 3 uses Bluetooth to pair with devices, offering a stable and robust connection. It can even pair with other Boom or Megaboom speakers, thanks to the PartyUp feature, creating a more powerful and immersive stereo experience.

Durability and Waterproofing

Durability is a significant aspect of the Boom 3, designed to survive in various environments. The IP67 rating ensures it’s completely waterproof and dustproof. Whether it’s a pool party or a dusty hike, the Boom 3 is built to endure. Its floatability is an added advantage, preventing it from sinking and making it easy to retrieve from water. The rugged build doesn’t compromise on style, as the speaker is available in various colors to suit different tastes.

User Experience and App Integration

The user experience is seamless with the Boom 3. The intuitive controls, combined with the Ultimate Ears app, enhance the speaker’s functionality. Through the app, users can access features like custom equalizer settings, remote on/off, and alarm function. The magic button also allows for playlist navigation from Apple Music or Deezer Premium, adding to the convenience. The speaker’s firmware is continually updated, introducing new features and improving performance over time.


In conclusion, the Ultimate Ears Boom 3 is more than just a speaker; it’s a robust, portable sound system designed for the modern audiophile. It impresses with its durable build, thoughtful features, and excellent sound quality. The speaker’s ability to produce 360-degree audio makes it the life of any party, ensuring that everyone gets the same sonic experience. Its waterproof and dustproof capabilities, coupled with the extended battery life, make it incredibly versatile and suited for any adventure.

While the Boom 3 is a fantastic product, it’s important to consider its competitors like the JBL Flip 5 or the Sony SRS-XB13 for those looking for different features or price points. Yet, with its blend of design, durability, and performance, the Ultimate Ears Boom 3 sets a high bar. It is an exemplary choice for those who refuse to compromise on their audio experience, whether at home or on the go. The Ultimate Ears Boom 3 is not just a speaker; it’s an indispensable companion for all music lovers, standing as a testament to what the future of portable audio can be.
