If you want better Stereo imaging accuracy
Choose JBL Go 5. It scores 4.8 vs 4.2 for Stereo imaging accuracy, with a 4.2 overall score.
Bottom Line
Choose the JBL Go 4 for an inexpensive, pocketable speaker that sounds lively, pairs easily, and shrugs off water and rough handling. Skip it if you need deep bass, all-day battery life, room-filling volume, calls, or wired audio.
Best for
It is best for travelers, students, hikers, beachgoers, and casual listeners who want an inexpensive speaker that disappears into a pocket or bag. It excels in personal spaces and small gatherings.
Not for
It is not for bass-focused listeners, large parties, all-day playback without charging, or anyone needing a microphone, voice assistant, Wi-Fi streaming, or wired audio.
Verdict
The JBL Go 4 succeeds by focusing on portability, durability, and uncomplicated everyday listening. Reviewers consistently praise its palm-sized, lightweight build, IP67 protection, quick Bluetooth setup, useful app EQ, and surprisingly lively output for the price. It is at its best on a desk, in a hotel room, at the beach, or providing background music for a small group. The compromises are equally clear: deep bass is limited, the presentation is mono and directional unless two units are paired, and maximum volume cannot cover a large gathering. Battery results vary, with several users falling short of the advertised figure, while Playtime Boost extends playback by thinning the sound. For casual grab-and-go use under $50, its ruggedness and convenience outweigh those limitations.

Pros
-
Its pocketable size, simple setup, and grab-and-go design make it exceptionally easy to use around the home, at work, or while traveling. Reviewers often describe it as a speaker they carry without thinking.
-
The compact shape, colorful fabric finishes, and rubber accents are widely praised as cute, modern, and premium-looking. Some buyers dislike the oversized JBL logo or particular accent colors.
-
Water protection is consistently praised: the IP67 speaker survives splashes, rain, dunking, and poolside use without trouble. Reviewers regularly treat it as a dependable beach, shower, and outdoor companion.
-
At roughly 190 grams, the speaker is exceptionally light and easy to slip into a pocket or bag. Its low weight is a defining advantage for travel, hiking, cycling, and everyday carrying.
-
The overall sound is lively, clear, and enjoyable for casual listening, with much more scale than the tiny enclosure suggests. It cannot match larger speakers for bass depth, openness, stereo width, or fine detail.
-
Durability is one of the strongest points: reviewers repeatedly report drops, bumps, travel, and outdoor abuse without meaningful damage. The rubberized edges and solid construction inspire confidence.
Cons
-
Sound is directional rather than truly room-filling in every direction. Reviewers often preferred laying the speaker face-up, while listening from behind it produced a muffled and narrower presentation.
-
There is no 3.5mm auxiliary input, and the USB-C port does not carry audio. Reviewers who still use older wired players consider this a clear limitation.
-
Complex tracks can sound muddled, with limited separation between instruments. The compact mono design favors an energetic, direct presentation over precise layering.
-
The soundstage has little vertical dimension and becomes muffled from behind the speaker. Its presentation is broader than expected for the size, but not spacious or three-dimensional.
-
The basic light communicates low battery and operating status, but reviewers wanted a more precise, graduated battery display. The app provides a clearer percentage readout.
-
The speaker has no native voice-assistant support, so commands must be made through the phone. Reviewers who wanted hands-free control viewed this as a notable omission.

FAQ
Is the JBL Go 4 waterproof?
Yes. Reviewers repeatedly confirm that its IP67 protection handles rain, splashes, beach use, and brief submersion without trouble.
How long does the battery last?
Many reviewers report roughly five to seven hours, while some get longer and others fall short. Playtime Boost can extend playback, but it noticeably reduces bass and overall sound quality.
Does it have strong bass?
Bass is punchy for such a small speaker, especially with EQ adjustments, but deep low bass is limited and thins out as volume rises.
Can two JBL Go 4 speakers play in stereo?
Yes. Two identical Go 4 speakers can form a true left-right stereo pair through the JBL Portable app; Auracast can also link compatible JBL models for wider mono coverage.
Does it have a microphone or AUX input?
No. It cannot function as a speakerphone, and it has no 3.5mm input; the USB-C port is for charging only.
Is the JBL Portable app useful?
Yes. Reviewers value its five-band EQ, presets, battery display, firmware updates, Playtime Boost control, and speaker-grouping tools, although the app is fairly basic.
