Product Overview

The JBL Go 4 is the latest in JBL’s iconic Go series, designed for ultimate portability without sacrificing audio quality. Measuring just a few inches in size and weighing under half a pound, it slips easily into your pocket, backpack, or gym bag. Its vibrant Red color option adds a pop of style, while the rugged build features an IP67 rating, meaning it’s fully waterproof (submersible up to 1 meter for 30 minutes) and dustproof—perfect for beach days, workouts, or rainy adventures.

At the heart of the JBL Go 4 is JBL’s Pro Sound technology, delivering surprisingly rich audio with punchy bass from its compact driver. Bluetooth connectivity is seamless and quick, supporting multi-device pairing. A standout feature is Auracast compatibility, allowing you to connect multiple JBL speakers for stereo sound or party mode amplification. Battery life hits up to 7 hours on a single charge, with a Playtime Boost mode adding another 2 hours at the tap of the app. Charging is via USB-C, and the speaker incorporates post-consumer recycled plastics and FSC-certified packaging, aligning with sustainable practices.

Pros

The JBL Go 4 shines in user-centric features that make it a standout. Here are the top advantages based on hands-on testing and widespread acclaim:

1. Exceptional Portability: Its tiny size and featherweight design make it the ultimate travel buddy. Reviewers rave about tossing it in a pocket for walks, runs, or commutes without any bulk.
2. Punchy JBL Pro Sound: Despite the small form factor, the bass is surprisingly deep and the overall sound is clear and balanced. It fills small rooms or outdoor spaces effectively for personal listening.
3. Impressive Battery Life: Up to 7 hours standard, extendable to 9 with Playtime Boost. Customers report real-world usage matching or exceeding claims, even at moderate volumes.
4. Rugged IP67 Build: Waterproof and dustproof ratings handle splashes, sand, and drops. Ideal for pool parties, beaches, or dusty trails—no need to baby it.
5. Easy Connectivity and Auracast: Bluetooth pairs instantly, and Auracast lets you link multiple units for stereo or amplified sound. No apps required for basics, but the JBL app enhances control.
6. Eco-Friendly Materials: Made with recycled plastics and sustainable packaging, appealing to environmentally aware buyers without compromising quality.
7. Affordable Price Point: At $39, it offers premium JBL performance at a budget price, delivering excellent value compared to competitors like Anker or Sony minis.

Cons

No product is perfect, and while the JBL Go 4 excels in portability, it has limitations typical of ultra-compact speakers. Here’s a balanced look at the drawbacks:

1. Limited Volume for Large Groups: It’s loud for personal use but may struggle in noisy environments or parties without pairing multiple units. Bass can distort at max volume.
2. Mono Sound by Default: Single-speaker playback is mono; stereo requires two Go 4s, adding cost for immersive audio.
3. No Built-in Microphone: Lacks hands-free calling or voice assistant integration, unlike some rivals with mics.
4. Battery Not Class-Leading: 7-9 hours is solid but trails larger speakers offering 20+ hours. Frequent users may need daily charging.
5. Auracast Compatibility: This future-proof feature requires other Auracast-enabled devices, limiting party mode for now to JBL ecosystem owners.

These cons are minor for its target audience but worth noting for power users seeking audiophile-grade performance.

Customer Reviews Analysis

With a glowing 4.8-star average from 13,766 reviews, the JBL Go 4 is a customer favorite. Positive feedback dominates, focusing on its “tiny but mighty” sound and reliability. A 5-star reviewer summed it up: “This is a great speaker. So small but great sound. I use it when I walk. Lightweight and connects to my phone via Bluetooth. Battery life is great. Price is great. Easy to use and connects with no issues.” Another echoed: “Love it. Tiny and powerful. Easy to connect. Love the colour too!”

Common praises include:

• Sound Quality (85% of reviews): Users are shocked by the bass and clarity from such a small device.
• Portability and Durability (70%): Perfect for workouts, travel, and outdoors; IP67 rating gets frequent mentions for surviving water exposure.
• Battery and Connectivity (60%): Quick Bluetooth pairing and solid playtime are highlights.
• Value for Money (50%): At $39, it’s seen as a steal compared to pricier alternatives.

Negative reviews are scarce (under 5%), often nitpicks rather than deal-breakers. Some complain about max volume limitations or wishing for longer battery, but even lower-rated feedback frequently praises build quality. For instance, one “0-star” labeled review (likely a data error) actually raved: “Excellent quality sound in a small highly portable package… battery life has been great.” Overall, 90%+ are 4-5 stars, indicating high satisfaction. Verified purchases confirm consistency, with few returns reported.

In comparison to predecessors like the JBL Go 3, the Go 4 improves on battery and Auracast, boosting ratings. It’s outpacing budget competitors in sound and durability per review aggregates.
