JBL Go 4 Portable Bluetooth Speaker (Red)

The JBL Go 4 is an ultra-portable Bluetooth speaker that delivers loud, punchy JBL Pro Sound in a waterproof, dustproof package with up to 7 hours of battery life.

The JBL Go 4 fits in the palm of your hand while offering clearer highs and richer bass than you’d expect from a speaker this size. With an integrated loop for easy carrying, IP67 protection against water and dust, and partially recycled materials, it’s designed for everyday adventures—whether that’s backyard barbecues, beach trips, or commuting. Pair two units for stereo or expand sound with multiple Auracast-enabled speakers to fill larger spaces.

How loud and full is the JBL Go 4 compared to other pocket speakers?

Despite its compact dimensions, the Go 4 produces a surprising amount of volume and bass for casual listening. JBL’s acoustic tuning focuses on clarity and low‑end punch so vocals and beats remain distinct even at higher volumes.

• Engineered JBL Pro Sound for clear mids and boosted bass
• Capable of stereo pairing with a second Go 4 for wider soundstage
• Expandable via Auracast to connect multiple speakers wirelessly

How long will the battery last on a single charge and what is Playtime Boost?

The built-in battery delivers up to 7 hours of continuous playback under typical listening conditions. If you need extra time, the Playtime Boost function can extend listening by up to about 2 additional hours when engaged.

• Standard playback: up to 7 hours per full charge
• Playtime Boost: roughly +2 hours when activated
• Rechargeable battery designed for daily portable use

Is the Go 4 durable enough for outdoor use and how do I care for it?

The Go 4 carries an IP67 rating, meaning it resists dust ingress and can be submerged briefly in water without damage. Rinse off sand and freshwater after exposure, avoid prolonged saltwater submersion, and allow the speaker to dry fully before charging.

• IP67 waterproof and dustproof protection for outdoor activities
• Easy-to-clean exterior and integrated carry loop for portability
• Keep charging port covers closed when exposed to water or dust

What connectivity options does the JBL Go 4 offer?

The speaker supports Bluetooth for quick wireless streaming from phones, tablets, and laptops. For larger listening setups, Auracast enables multi-speaker broadcasts and two Go 4 units can be linked for stereo playback.

• Bluetooth wireless streaming for most devices
• Stereo pairing with a second JBL Go 4
• Auracast support to connect multiple compatible speakers

Who is this for: The JBL Go 4 suits anyone seeking truly portable sound that stands up to everyday outdoor use—commuters, students, small gathering hosts, and travelers who want reliable audio in a compact, colorful package. It’s an especially good fit for buyers who value easy carry, IP67 protection, and the option to scale sound by pairing or using Auracast, all while choosing from eco-conscious materials and bold colorways.
