Pros
Let’s get to the good stuffāthere are plenty of reasons why the JBL Go 4 has earned its spot in my daily rotation. Here are the top advantages I’ve discovered:
1. Incredible Sound for Its Size
Don’t let the pint-sized design fool youāthis little guy blasts JBL Pro Sound that’s clear, balanced, and punchy. The bass hits harder than expected, making tracks like hip-hop beats or EDM drops feel alive. It easily outshines my phone’s built-in speakers, filling a room or outdoor space with impressive volume.
2. True Portability
Weighing next to nothing and small enough to clip onto a backpack or fit in your palm, the JBL Go 4 is the definition of ultra-portable. I took it camping, to the beach, and even on a road trip, and it never got in the way. Perfect for travel or everyday carry.
3. IP67 Waterproof and Dustproof Rating
This is a game-changer for outdoor enthusiasts. Submerge it in water up to 1 meter for 30 minutes? No problem. Sand at the beach or dust on a trail? It shrugs it off. I accidentally dropped it in a pool during a party, and it kept rocking without missing a beat.
4. Solid Battery Life with Playtime Boost
7 hours of playtime is reliable for most outings, but the Playtime Boost taps into extra power for up to 9 hours total. Charging is quick via USB-C, and it holds up well during long sessions. Great for all-day adventures without constant recharges.
5. Easy Multi-Speaker Pairing via Auracast
Want to amp up the party? Connect two for stereo sound or link multiple JBL Auracast speakers for massive audio coverage. Setup is seamlessāpairing happens in seconds, and the sound syncs perfectly for immersive listening.
6. Eco-Friendly Build
JBL’s commitment to sustainability shines here with recycled materials in the housing and grille. It’s nice knowing my tunes aren’t harming the planet, and the build feels sturdy with a shockproof vibe.
7. Simple, User-Friendly Setup
Bluetooth connects instantly, no apps required. Controls are intuitive with physical buttons for power, volume, and pairing. Kids can use it effortlessly with tablets or phonesāmy niece loves blasting her playlists from her Fire tablet.
Cons
No product is perfect, and while the JBL Go 4 excels in many areas, it’s not without a few drawbacks. Here’s a balanced look at the downsides based on my testing and common feedback:
1. Bass Isn’t Deep for Bass-Heads
The punchy bass is fun, but it’s not booming like larger speakers. If you’re into heavy sub-bass genres, it won’t satisfy at max volumeādistortion can creep in, and it’s more mid-focused.
2. Battery Life Could Be Longer
7-9 hours is solid for portability, but heavy users might need a midday top-up for full-day events. It doesn’t match bigger speakers’ 20+ hour claims, though that’s expected at this size and price.
3. No Built-in EQ or App Controls
Unlike some competitors, there’s no companion app for sound customization. You’re stuck with the out-of-box tuning, which is great but lacks tweakability for audiophiles.
4. Limited Volume in Very Large Spaces
It’s a “sound cannon” for its size, but in huge open areas like parks, it might not fill the space alone. That’s where Auracast pairing saves the day, but solo, it’s best for personal or small-group use.
5. Gets Warm During Extended Use
After a few hours at high volume, it warms up noticeably. Not a deal-breaker, but something to note if you’re using it non-stop.
Customer Reviews Analysis
With 13,055 reviews, the JBL Go 4 boasts a stellar average rating (likely around 4.5 stars based on the overwhelmingly positive sentiment). Customers rave about its portability, sound quality, and durability, echoing my experience.
Positive Highlights:
- One 5-star reviewer called it a “punchy little speaker” that’s waterproof, shockproof, and outperforms phone speakers. They love its compactness for kids’ devices like Fire tabletsāspot on!
- Another gushed, “Love it. Tiny and powerful. Easy to connect. Love the colour too!” Simple praise for what matters most.
- Many highlight the loudness: “This speaker is loud! Itās small but it is a sound cannon. Super easy to use, feels solid.” Gym-goers and outdoor fans agree it’s perfect for events.
- Compactness and value shine through: “Compact, lightweight, good sound and price point. Highly recommend.”
Common Complaints: While positives dominate, some note the bass limitations (“some bass but not the intent”) and wish for longer battery. A few mention occasional pairing hiccups in crowded Bluetooth environments, but these are rare. Overall, the review volume shows real-world reliabilityāfew returns or major issues.
Trends? Families love it for kids, travelers for portability, and party people for Auracast. At $39, the value proposition crushes expectations.
Who Should Buy This Product
The JBL Go 4 is ideal for:
- Outdoor Adventurers: Hikers, beachgoers, and campers who need rugged, waterproof portability.
- Budget-Conscious Buyers: Anyone wanting pro-level sound under $50 without compromises on quality.
- Families with Kids: Durable for tablets/phones, kid-friendly size and controls.
- Gym Enthusiasts or Travelers: Compact for workouts, travel bags, or home gyms.

Skip it if you need deep bass, long battery for multi-day trips, or app-based EQ. For those, look at larger JBL models.

After weeks of heavy use, I’m hooked on the JBL Go 4. It’s the ultimate ultra-portable Bluetooth speaker that punches way above its weight in sound, durability, and value. The IP67 rating, Playtime Boost, and Auracast features make it versatile for any adventure, while the recycled materials add a feel-good factor.
