JBL Go 4 - Ultra-Portable, Waterproof and Dustproof Bluetooth Speaker, 7-Hour Built-in Battery, Made in Part with Recycled Materials (Blue)

While the JBL Go 4 delivers impressive sound clarity and volume for its compact 190-gram build, user feedback highlights its limitations in deep bass response. Many users express astonishment at the sound quality achievable from such a small device, describing it as 'punchy' and 'clean' at moderate volumes, making it excellent for personal listening or background music. However, when pushed to higher volumes or during playback of tracks with heavy bass lines, the bass can become thin. It excels at low volume listening, providing a surprisingly rich audio experience without causing listening fatigue.

The JBL Go 4 supports multi-speaker connection via Auracast technology, enabling you to wirelessly link multiple compatible JBL speakers for an expanded audio experience. You can pair two Go 4 speakers for a stereo soundstage, enhancing immersion. Furthermore, Auracast allows connection to other JBL speakers equipped with this feature for wider sound coverage during larger gatherings. This technology is designed for seamless integration, although optimal performance can depend on environmental signal interference and the total number of connected devices.

Compared to the Sony SRS-XB100, the Go 4 is often noted as more compact, though the Sony may offer longer battery life. Against the Ultimate Ears WONDERBOOM 4, the Go 4 is significantly smaller and lighter. The WONDERBOOM 4 is generally perceived as more durable, floats, and boasts longer battery life. Users frequently select the Go 4 when maximum portability and a smaller footprint are the highest priorities, appreciating its 'hyperultramegaportable and light' design. While competitors might offer more solidness or extended playtime, the Go 4's sound-for-size ratio remains a key differentiator.

Some users have reported occasional instances where the speaker unexpectedly shuts off, though this does not appear to be widespread. The primary sonic limitation noted is that the bass response can be thin at higher volumes or with bass-heavy music, which is an inherent characteristic of its ultra-compact design. For personal listening or background audio at moderate levels, the sound quality is generally praised for its clarity and volume relative to its size.
