JBL Go 4 Portable Bluetooth Speaker — Pink, Ultra-Portable IP67 Waterproof, 7‑Hour Battery & Big JBL Pro Sound

The JBL Go 4 is an ultra‑portable Bluetooth speaker that delivers surprisingly big JBL Pro Sound with punchy bass, IP67 water and dust resistance, and up to 7 hours of battery life in a pocketable design.

Compact and colorful, the JBL Go 4 is built for on‑the‑go listening. It slips into a bag or clips to a strap via its integrated loop, resists splashes and sand thanks to an IP67 rating, and uses recycled materials in its grille and packaging. Designed to pair with another Go 4 or multiple Auracast‑enabled JBL speakers, it scales from personal listening to louder stereo setups without changing its palm‑sized footprint.

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

Despite its size, the Go 4 focuses on clarity and bass impact for a lively listening experience. JBL tunes the driver to emphasize midrange detail and low‑end punch so vocals and beats come through clearly at higher volumes.

• JBL Pro Sound tuning for balanced highs and punchy bass
• Optimized driver and enclosure for maximum output from a compact cabinet
• Pair two units for true stereo separation and wider soundstage

Will it survive a day at the pool or beach?

Yes — the Go 4 carries an IP67 rating, meaning it’s both waterproof and dustproof. That protects it from accidental splashes, brief submersion, and fine particles like sand, so you can use it outdoors with less worry.

• IP67: dustproof and water immersion protection
• Sealed ports and durable housing for outdoor durability
• Integrated loop for secure attachment to bags or straps

How long does the battery last and can I extend playtime?

The internal battery delivers up to 7 hours of playback per full charge under typical listening conditions. When you need a little extra, the Playtime Boost feature can extend runtime by up to about 2 more hours so your music lasts through short outings.

• Up to 7 hours of continuous playback on a single charge
• Playtime Boost adds roughly 2 additional hours when activated
• Efficient power management for reliable day‑use performance

Can I connect multiple JBL speakers for bigger sound?

Yes — the Go 4 supports multi‑speaker connections using Auracast technology. You can pair two Go 4 units for stereo playback or join several Auracast‑enabled JBL speakers to create a larger synchronized audio network.

• Pair two Go 4s for left/right stereo separation
• Connect multiple Auracast‑enabled speakers for expanded sound
• Simple wireless pairing and quick reconnection to devices

Who is this for? The JBL Go 4 is ideal for listeners who want bold JBL audio in a truly pocketable package: commuters, travelers, picnic‑goers, and anyone who wants a tough, water‑resistant speaker for casual outdoor use. It’s also a smart choice for eco‑minded buyers who appreciate post‑consumer recycled materials in the grille and FSC‑certified packaging. If you need louder, room‑filling sound occasionally, you can expand with a second Go 4 or other Auracast‑enabled speakers.
