JBL Go 4 (Squad) Ultra-Portable Waterproof Bluetooth Speaker

In this review of the JBL Go 4 (Squad), the bottom line is simple: this is a pocket-ready Bluetooth speaker for people who want surprisingly big JBL Pro Sound from a tiny, rugged package. The reviewer found it excels at outdoor use thanks to an IP67 waterproof and dustproof design and a convenient integrated loop for carrying. With clear, punchy bass and simple pairing, the Go 4 is best for day-trippers, patio listeners and anyone who values portability and durable construction over full-sized speaker features.

Key Features

• Ultra-portable JBL Pro Sound: Delivers clearer-than-expected audio and punchy bass from a palm-sized speaker, making it easy to bring quality sound anywhere.
• Up to 7 hours playtime: Provides a full day of casual listening and includes a Playtime Boost option to extend battery life by about 2 hours when needed.
• IP67 waterproof and dustproof: Built to withstand poolside splashes, sand and light exposure so it can be used outside without worry.
• Multi-speaker Auracast connection: Lets you pair two Go 4 units for true stereo or connect multiple Auracast-enabled speakers for larger coverage.
• Partially recycled construction: Uses post-consumer recycled plastic and recycled fabric for the grille and comes in FSC-certified paper packaging.

Who It's For

The JBL Go 4 is aimed at listeners who need an ultra-portable speaker that survives outdoor conditions and still sounds punchy. It fits campers, beachgoers, commuters and anyone who wants a small speaker that can easily attach to a bag or hang from a loop.

It is less well suited for those who need long marathon playback without recharging or audiophiles seeking room-filling hi-fi detail; buyers wanting extended battery life or a more powerful low end should consider larger portable speakers instead.
