The JBL Go 4 is the ultimate pocket-sized audio companion, re-engineered for 2026 to deliver a surprisingly powerful sonic experience. Despite its small footprint, this ultra-portable speaker features an upgraded 45mm transducer and a new, more efficient amplifier that pumps out JBL Pro Sound with richer, punchier bass than its predecessors. Whether you are at a backyard hangout or a beach party, the Go 4 delivers clear, loud audio that belies its compact size.
Built for the adventurous, the JBL Go 4 features an IP67 waterproof and dustproof rating, meaning it can survive being submerged in up to 1 meter of water for 30 minutes. The rugged design is further enhanced with a wider rubberized edge and a redesigned integrated loop, making it easy to clip onto a backpack or belt loop for music on the move. In a step toward sustainability, the speaker is crafted using post-consumer recycled plastic and fabric, and comes in eco-friendly FSC-certified packaging.
The technology inside the Go 4 is as impressive as its build. It utilizes the latest Bluetooth 5.3 for a stable, energy-efficient connection and introduces Auracast™ connectivity. This allows you to wirelessly pair two Go 4 speakers for immersive stereo sound or connect multiple Auracast-enabled JBL units to create a larger soundstage. With up to 7 hours of playtime—plus an additional 2 hours using the Playtime Boost feature—the Go 4 keeps the party going from day to night. You can even customize your listening experience through the JBL Portable app, which offers full EQ control and firmware updates.
