JBL Compact Bluetooth Speaker GO4-ULTRA

The JBL GO 4 Ultra Portable Bluetooth Speaker takes your listening experience to the next level with enhanced sound, durable construction, and smart connectivity features. Redesigned from the ground up, the GO 4 introduces JBL’s latest audio platform, featuring a 16% larger driver unit and optimized amplifier for richer, more powerful sound — all packed into a compact, palm-sized body.

For the first time in the GO/CLIP series, the JBL GO 4 is compatible with the JBL Portable app, allowing users to adjust EQ settings, rename their device, toggle startup sounds, and update firmware with ease. It also introduces LE Audio and Auracast technology, enabling seamless wireless stereo pairing and audio distribution across multiple compatible devices.

Enjoy up to 9 hours of continuous playback on a single charge, extended further by “Playtime Boost,” which optimizes power use for even longer sessions. With an IP67 waterproof and dustproof rating, the GO 4 is built to handle outdoor adventures — from the beach to the shower — without compromise. The waterproof USB-C port ensures durability even when exposed to moisture or dirt.

The structure of the JBL GO 4 has been refined for improved durability and portability, featuring a reinforced cushion frame and a redesigned loop handle. Built with sustainability in mind, it uses recycled plastic and fabric materials, and eco-friendly packaging printed with biodegradable soy ink.

Offered in a vibrant range of colors including Camouflage, the JBL GO 4 combines modern aesthetics, durable construction, and JBL’s signature sound — making it the perfect everyday companion for music lovers on the move.
