JBL GO 4-RED

The JBL Go 4 is the 2024/2025 update to JBL’s ultra-compact “pocket” speaker. In 2026, it remains the top choice for travelers and hikers who need something virtually weightless but loud enough for personal use.

## Technical Specifications

## Key Upgrades: Go 4 vs. Go 3

• Battery Expansion: The Go 4 jumps from the Go 3’s 5 hours to a base of 7 hours. The new “Playtime Boost” feature in the app can extend this by another 2 hours by optimizing the output (though this slightly reduces the deep bass).

   

• Auracast™ Support: This is the smallest speaker in the world to feature Auracast. You can now wirelessly pair two Go 4s for true stereo sound or link it to a massive network of other Auracast-enabled JBL speakers (like the Flip 7 or PartyBox 120).

   

• Full EQ Control: For the first time in the Go series, you can connect to the JBL Portable App. This gives you a 5-band equalizer to customize the sound—perfect if you want to dial back the treble or squeeze a bit more “thump” out of the tiny driver.

   

• Redesigned Durability: The “nubs” on the bottom of the Go 3 have been replaced with a fully rubberized grid that prevents the speaker from sliding around on wet or uneven surfaces.

• Eco-Friendly Build: It is made from post-consumer recycled plastic and fabric, wrapped in plastic-free, FSC-certified packaging.
