JBL Go 4 Portable Bluetooth Speaker - White

Compact and waterproof, the JBL Go 4 is a palm-sized Bluetooth speaker that delivers clear JBL Pro sound, punchy bass, up to 7 hours of playtime, and IP67 durability in a travel-friendly design.

The JBL Go 4 blends pocketable size, durable construction, and recognizable JBL audio tuning into a speaker built for everyday adventures. This certified refurbished white unit keeps the same physical loop, water- and dust-resistant housing, and Bluetooth pairing features found in new models, while using recycled materials where possible. It’s designed to be carried, clipped, and played outdoors or inside — offering portable audio without oversized bulk.

How loud and full is the JBL Go 4 for its size?

Despite its small footprint, the Go 4 is tuned to produce balanced mids and emphasized low-end for a fuller listening experience than you might expect. Pairing two units creates stereo separation for a wider soundstage.

• JBL Pro sound profile engineered for clarity and bass presence
• Option to pair two Go 4 speakers for true stereo playback
• Works with multiple Auracast-enabled speakers for larger setups

Will it survive outdoor use and beach days?

The Go 4 carries an IP67 rating, meaning it resists both dust ingress and temporary water immersion — suitable for poolside use, light rain, or sandy spots. Its integrated loop simplifies attachment to bags or straps so you can keep it secure on the move.

• IP67 waterproof and dustproof housing for rugged environments
• Built-in loop for easy clipping to gear or backpacks
• Compact shape that resists accidental knocks and splashes outdoors

How long will the battery last during a day out?

A single charge delivers up to 7 hours of continuous playback under typical listening conditions, with an additional short-playtime feature that can extend runtime by roughly 2 hours when needed. Actual battery life varies with volume level and audio content.

• Up to 7 hours of playtime on a full charge
• Playtime Boost option adds about 2 more hours in urgent situations
• Rechargeable battery via the speaker’s charging port

What sustainability and material choices does it include?

The Go 4 integrates post-consumer recycled plastics and a recycled fabric grille to reduce environmental impact, and packaging uses FSC-certified paper printed with soy-based inks. Choosing a certified refurbished unit further extends the product lifecycle by diverting devices from landfill.

• Speaker grille made with recycled fabric
• Post-consumer recycled plastic components in the enclosure
• FSC-certified paper packaging and soy ink printing

Who this is for: The JBL Go 4 in white (certified refurbished) is ideal for commuters, travelers, and anyone wanting a lightweight, durable speaker that fits in a pocket or hangs from a bag. It suits listeners who value portability and environmental choices, need a weather-resistant unit for outdoor activities, or want an affordable way to expand sound by pairing multiple JBL speakers.
