When you're looking for a portable speaker in 2024, the range of options can be overwhelming. Today we're comparing two very different approaches: the premium Ultimate Ears EPICBOOM at $229.99 and the ultra-portable JBL Go 4 at $44.00. While both are Bluetooth speakers, they serve distinctly different needs and user groups.
The EPICBOOM, released in late 2023, represents Ultimate Ears' latest flagship portable speaker, while the JBL Go 4, launched in early 2024, continues JBL's popular ultra-compact speaker line. These release timings mean both devices feature modern connectivity like Bluetooth 5.3, but they take vastly different approaches to portable audio.
The EPICBOOM uses a sophisticated three-driver system: two 45mm mid-high frequency drivers and a substantial 120mm woofer. This configuration delivers impressive 360-degree sound, meaning you can place it centrally in a room and get consistent audio quality from any direction. In testing, it produces clear, detailed audio with particularly strong performance in the midrange - think vocals and acoustic instruments.
The bass response is notably good for a portable speaker, though it won't replace a proper subwoofer. At maximum volume (94 dBC), it can easily handle outdoor gatherings or fill a large room, maintaining clarity without distortion.
In contrast, the JBL Go 4 uses a single 45mm driver, focusing on clear, directional sound. While it can't match the EPICBOOM's volume or bass response, it produces surprisingly balanced audio for its tiny size. The speaker reaches about 83 dBC - plenty for personal listening or small group settings.
What's particularly impressive about the Go 4 is how JBL has improved the sound quality over its predecessor. The new model offers noticeably better clarity in the mid-range and more balanced treble response, though bass is still limited by its physical size.
The portability difference between these speakers is striking. The EPICBOOM weighs nearly 2kg and is about the size of a large water bottle, while the Go 4 weighs just 190g and easily fits in a pocket. This fundamental difference drives many of their use cases.
Both speakers feature IP67 water resistance ratings, meaning they can handle dust and temporary water immersion. The EPICBOOM adds the ability to float, making it perfect for pool parties. The Go 4's smaller size makes it more durable against drops and easier to protect.
Battery life follows a similar pattern to size - the EPICBOOM offers 17 hours of playback, while the Go 4 manages 7 hours. Both use USB-C charging, but the EPICBOOM takes longer to charge due to its larger battery capacity.
Both speakers support Bluetooth 5.3, offering excellent range and stability. The EPICBOOM includes NFC for easy pairing, while the Go 4 offers JBL's new Auracast technology for connecting multiple speakers.
The EPICBOOM includes several advanced features:
The JBL Go 4 keeps things simpler but includes:
The EPICBOOM excels when:
The Go 4 makes more sense when:
At $229.99, the EPICBOOM needs to justify its premium price. For users who will take advantage of its superior sound quality, longer battery life, and advanced features, it delivers excellent value. The sound quality alone makes it worth considering for primary home audio use in smaller rooms.
The Go 4's $44.00 price point makes it an easy recommendation for anyone needing a capable portable speaker. While it can't match the EPICBOOM's performance, it offers remarkable value for personal use and travel.
Consider these key factors when choosing:
Both speakers excel in their intended use cases. The EPICBOOM offers premium sound and features for those who need them, while the Go 4 provides excellent value and portability for personal use. Your choice should align with your specific needs and use cases rather than purely focusing on specs or price.
