Go 4

Reviewer verdict

Across 21 YouTube reviews, the JBL Go 4 earns a Summa score of 4.2/5, ranking #5 among Bluetooth Speakers. Reviewers most often praise its features, design, connectivity, while the most common criticisms concern sound quality, features.

The JBL Go 4 is repeatedly praised by reviewers for its compact, portable design and premium-feeling materials, with about 41 mentions highlighting its modern look, recycled fabric, rubberized edges, and convenient carry loop. Reviewers also widely applaud built-in features and app support (around 36 mentions), especially the JBL Portable app’s five-band EQ, OraCast/Arcast multi‑speaker pairing and firmware updates. Battery life and charging receive frequent positive notes (about 34 mentions) for the jump to roughly 7 hours of playback, USB‑C charging and a playtime‑boost mode. Sound, connectivity and durability are recurring strengths too, with many noting clear mids/highs, loud output for the size, Bluetooth 5.3 stability and an IP67 dust/water rating across multiple reviews.

Criticisms cluster around sound limitations (about 20 cons), where reviewers commonly call out thin or reduced bass—especially when using Playtime Boost that disables EQ—and some harsh mids or limited soundstage for demanding genres. Feature shortcomings are also noted (about 18 cons), including the lack of a microphone, no AUX input, a short included USB‑C cable and limited usefulness of some app EQ presets unless you use Arcast. Battery and charging drawbacks appear in several reviews (about 12 cons), with real‑world run time falling at higher volumes and a relatively slow ~3‑hour charge due to lack of fast charging. Connectivity and value concerns surface too, including Arcast incompatibility with older PartyBoost speakers, occasional Arcast glitches, and some reviewers finding the price marginal for the improvements cited.
