The JBL Go 4 continues JBL’s legacy of creating ultra-portable speakers that deliver surprisingly big sound despite their small footprint. Designed for everyday use—from study sessions and desktop listening to outdoor mini-adventures—the Go 4 is built to be lightweight, durable, and impressively loud for its size. With punchier bass, improved playtime, enhanced waterproofing, and new Auracast multi-speaker connectivity, the Go 4 is a significant upgrade over previous models. Whether you’re on a walk, heading to the beach, or simply want a tiny speaker with reliable JBL Pro Sound, this compact powerhouse fits the role perfectly.
Despite its compact frame, the Go 4 delivers unexpectedly powerful audio. The speaker produces more defined vocals, richer lows, and better clarity than the Go 3. JBL’s tuning ensures the sound remains bold and full even at higher volumes, making it suitable for both indoor and outdoor listening.
The built-in 700 mAh battery delivers up to 7 hours of continuous playback. For users needing a little extra time, Playtime Boost adds approximately 2 more hours by optimizing performance and reducing bass output. It’s ideal for commuting, casual travel, or small gatherings where charging may not be convenient.
The JBL Go 4 comes with an IP67 rating, making it resistant to dust, sand, splashes, and complete water immersion. Whether you're at a poolside hangout, beach picnic, or hiking trail, the speaker is built to withstand tough outdoor conditions.
A major upgrade is Auracast support—a feature that allows two JBL Go 4 speakers to pair together for true stereo sound. Users can also link multiple Auracast-enabled JBL speakers to amplify the sound across a room or outdoor environment, creating a broader listening experience.
The Go 4 incorporates post-consumer recycled plastic and fabric into its construction. JBL also uses environmentally friendly packaging like FSC-certified paper and soy-ink printing, making the product more sustainable without compromising quality.
At just 0.19 kg, the speaker is lightweight and easy to carry. A built-in loop mount allows users to hook it onto backpacks, belt loops, or handlebars for hands-free portability.
The JBL Go 4 is priced at $39.95 in the United States, with a limited-time offer available on Amazon US. Considering its enhanced audio performance, waterproof rating, and Auracast connectivity, it remains one of the best-value mini speakers in its category.

The JBL Go 4 stands out as a compact speaker that outperforms expectations. Its improved driver delivers louder and punchier audio, especially in the bass department—something rarely seen in budget mini speakers of this size.

Auracast support elevates the experience dramatically, allowing users to create a stereo setup or multi-speaker system effortlessly. This feature alone makes the Go 4 more versatile than many competing portable speakers.
