JBL Go 4 - Ultra-Portable, Waterproof and Dustproof Bluetooth Speaker, Big Pro Sound with Punchy bass, 7-Hour Built-in Battery, Made in Part with Recycled Materials (Red)

Solid speaker, loud, clear, small.Background: I have owned a lot of computer speakers and speakers of all sizes and I work as in audio. I'm not a complete expert, but I do have a ton of experience in all things sound. For a speaker that can fit in your pocket, this thing is really good. I bought it for a vacation, so we could play music in our cabin, and it delivered well beyond my expectations. It was plenty loud, with more room to go. There is a major difference from listening to things straight from a laptop, tablet, or phone with little effort and it sounds pretty close to a real speaker setup.Battery: The battery lasted just around 8 hours of nearly continuous play. A nice feature: it shuts down after awhile if it does not detect a signal from your device. Great for saving battery and not forgetting to turn it off.Build Quality: Very durable, it seems. It has a rubber shell. I would say you could drop this off a roof and it would survive. A nice option for camping, vacations, bonfires, rugged activities where it may take some abuse, but also where a power supply doesn't come easy and you need portability. The blue color with grey and orange accents is really nice.Sound Quality: I found the sound to be clear, with plenty of volume. There are speakers that project nicely, without being "loud" - I would not put this into that category, but those speakers cost at least 4x the price. There were times where it seemed to be getting too loud for everyone. But, for the price, that is nothing to complain about. There is a lot of bass, but not a crazy amount (which a lot of brands think more bass means good). It has a pretty even EQ; you can hear everything well. Since it is portable, just move it around the room and find the best spot where it can be heard, but won't be in everyone's face, isn't bouncing off reflections like hard surfaces, and it will sound awesome.Value: Well worth the money. I will be using this a lot, i can already tell. JBL is a very experienced brand in this department. I have heard other bluetooth speakers. Although I haven't A/B compared anything else, this one sounds just as good as anything else out there I can remember, including the more expensive JBL tube.

The JBL Go 4 delivers impressive performance for its size and price. It works well for everyday listening, with clear sound quality and surprisingly strong bass for a compact speaker. The volume control is responsive and easy to manage directly from the unit or through a connected device.Functionality is straightforward—Bluetooth pairing is quick and reliable, and the speaker holds a stable connection. The build quality feels solid, with a durable outer shell that can handle daily use and minor drops without issue.Available in a variety of vibrant colors, the Go 4 adds a fun, personalized touch to your setup. Given its sound performance, portability, and features, it offers excellent value for money for casual listeners and those on the go.

I bought the JBL Go 4 in March 2025 on Amazon, mainly for use in the shower, and I’ve been seriously impressed. For such a small, ultra-portable speaker, it delivers amazing sound quality with surprisingly punchy bass. It gets plenty loud, although you may notice a bit of distortion at the highest volume levels - nothing unexpected for a speaker of this size.Bluetooth connection is solid, and the range has been more than sufficient whether I’m using it in the bathroom or outside. The battery life has been excellent - I haven’t tested the full 7-hour limit since I usually top it off before then, but it’s never come close to dying on me. Charging is fairly quick, depending on the charger you’re using.I’ve also taken it with me on a camping trip, and it proved to be rugged enough to handle outdoor use. It held up great in wet and dusty conditions, and has handled regular use in the shower without any issues. So I’d say the waterproofing holds up well based on my experience.The build quality feels premium with a grippy rubberized housing that’s easy to hold, and the compact size makes it perfect to toss in a bag or hang on a hook. I didn’t buy it for the recycled materials, but it’s a nice bonus to know it’s made with sustainability in mind.I’m giving the Go 4 a solid 5 stars because it truly delivers on sound, durability, and portability for the price. I’d recommend it to anyone looking for a dependable shower speaker or something to use on a camping trip where you want clear sound without being disruptive to others nearby. It just works.

I’m seriously impressed with the JBL Go 4! Don’t let the small size fool you — the sound is clear, rich, and surprisingly loud for such a compact speaker. It’s perfect for my desk, travel, or tossing in a bag for a day out on the golf course.The built-in finger loop makes it easy to carry, and the waterproof/dustproof design gives me peace of mind when I’m using it outdoors. Battery life has been solid — I’ve gotten close to 9 hours with the Playtime Boost feature on.All in all, this is a fantastic little speaker that punches way above its weight.

Just what I needed! I bought a couple of these because our TVs are getting old and the sound isn't great. This puts the sound near me as I cook in the kitchen, banging pots and pans, so I can hear without blasting the house. It connects easily with the TV has just the right amount of controls and is easy to see if it needs charging. PLUS its waterproof, so I can take it to the bath if I want to soak a bit. Good product, price is right, sound isn't perfect but great for the price and better than other speakers.
