JBL Go 4 Ultra-Portable Bluetooth Speaker — Black & Orange, IP67 Waterproof, 7-Hour Battery

Compact enough to slip into a bag or clip to a backpack, the JBL Go 4 is built for everyday adventures — from beach days to backyard barbecues. It combines a tough IP67-rated shell that repels water and dust with a refreshed design and recycled-material components, so you get durable performance with a smaller environmental footprint. Pair it wirelessly for wider stereo sound or use a single unit as a reliable, travel-ready audio companion.

How loud and full is the sound from such a small speaker?

Despite its small size, the Go 4 is voiced for clarity and bass impact that belies the form factor. JBL Pro Sound tuning emphasizes midrange detail and punchy bass so vocals and beats come through clearly at higher volumes.

• Palm-sized driver architecture optimized for fuller mid and low tones
• JBL Pro Sound tuning for clear vocals and defined bass
• Pair two Go 4 units for true stereo separation
• Wireless Auracast linking to connect multiple JBL speakers

Will it survive spills, sand, or a rainy outing?

The Go 4 carries an IP67 rating, meaning it is both waterproof and dustproof — designed to operate after accidental submersion and resist particles like sand. That makes it a practical pick for outdoor use where conditions are unpredictable.

• IP67 protection: water immersion and dust resistance
• Sealed ports and robust housing for active use
• Lightweight, durable loop for secure attachment on the go
• Ideal for poolsides, parks, beaches, and dusty trails

How long does battery life last, and are there ways to extend playtime?

A single charge powers the speaker for up to 7 hours of continuous playback, suitable for daytrips and evening gatherings. A built-in Playtime Boost mode can extend that runtime by up to an additional 2 hours when you need a little extra listening time.

• Standard playtime: up to 7 hours on a full charge
• Playtime Boost: adds up to 2 bonus hours when activated
• Rechargeable battery with quick charging convenience
• Efficient power use for prolonged outdoor sessions

Is the Go 4 environmentally considerate, and how does it connect to other devices?

JBL integrates post-consumer recycled plastics and a recycled fabric grille into the Go 4, while packaging uses FSC-certified paper and soy ink. For audio, Bluetooth connectivity and Auracast compatibility let you pair two Go 4 speakers or wirelessly link multiple Auracast-enabled JBL models for larger soundscapes.

• Constructed with some post-consumer recycled materials
• FSC-certified packaging printed with soy-based ink
• Bluetooth pairing and two-speaker stereo capability
• Auracast support to connect many JBL speakers simultaneously

Who is this for? The JBL Go 4 is aimed at anyone who wants reliable, big-sounding audio in a truly portable package: commuters, students, travelers, outdoor enthusiasts, and casual listeners who value durability and easy transport. If you need a compact speaker that resists weather and dust, offers solid battery life, and can scale up sound by linking additional JBL speakers, the Go 4 is a practical, wallet-friendly choice that balances performance and portability.
