JBL Go 4 – Ultra-Portable, Waterproof and Dustproof Bluetooth Speaker Pro Sound with Punchy bass
The JBL Go 4 is an ultra-portable micro Bluetooth speaker that delivers surprisingly loud JBL Pro Sound and punchy bass relative to its palm-sized design. It features a rugged IP67 waterproof and dustproof build and offers up to 7 hours of battery life, making it an exceptional companion for outdoor adventures, poolside relaxation, or travel.
Key Features and Performance Upgrades
- Upgraded Sound Quality: Outfitted with a 45mm transducer pushing 4.2 watts RMS. Experts from SoundGuys note that while its pocket size limits true sub-bass rumble, it delivers a clear, mid-heavy sound that punches well above its weight class.
- Extended Playtime: Yields up to 7 hours of standard playback on a 3-hour charge via its USB-C port. Activating the “Playtime Boost” feature inside the app stretches the battery by an extra 2 hours (up to 9 hours total) by optimizing the audio profiles.
- Advanced Connectivity: Powered by Bluetooth 5.3 for reliable range and multipoint pairing, allowing you to connect to two devices simultaneously. [
- JBL Auracast Ecosystem: Includes a dedicated Auracast button to wirelessly link two Go 4 speakers for true stereo sound, or to group multiple Auracast-enabled JBL models for amplified mono playback. [
- App Customization: Unlike older generations, it seamlessly integrates with the JBL Portable App to unlock a customizable 5-band Equalizer (EQ) alongside automated software updates. [
- Eco-Friendly Design: The speaker’s exterior is constructed in part using post-consumer recycled plastic and fabric for the main grille, and it arrives packaged in FSC-certified paper printed with soy ink.
