JBL Go 4 Portable Bluetooth Speaker

The JBL Go 4 is an ultra-compact, waterproof Bluetooth speaker designed for portability and durability. It features a single driver with punchy bass and JBL Pro Sound, rated IP67 waterproof and dustproof for submersion protection. Battery life reaches 7 hours per charge with fast-charging via USB-C. The speaker supports Bluetooth 5.3 with a typical range of ~10 meters and pairs with multiple speakers for stereo mode. Measuring just 4.3" × 2.1" × 1.8" and weighing 192g, it's genuinely pocketable with a carabiner clip. The chassis mixes recycled plastics with rugged rubberized grips. Community feedback praises its durability, waterproof seal, and compact footprint; some note the single driver limits soundstage and bass can be boomy at maximum volume. Best for outdoor adventures, poolside, travel, and budget-conscious buyers seeking JBL quality without premium pricing.
