    Holy wow, I didn’t know this was possible!
    Holy Cow. These things are AMAZING!  My wife and I go kayaking pretty often and we had the 3 version so only one of us could really hear it at a time. Decided to upgrade to the 4s because they’re able to connect to each other. Works perfectly! Then, I got the app for JBL and saw they could do stereo sound. Figured I’d try them with a good test song for stereo out on my deck, Bohemian Rhapsody by Queen(see picture for where I have the speakers away from themselves). It is crazy how well they can do stereo! It’s pretty much like if I was wearing earphones for the stereo they can make happen! Would I recommend these? Definitely! One sounds great by itself, crazy loud at full volume with absolutely no distortion. Get two? 100% more crazy amazing! If you’re looking for a great portable speaker for the boat/beach/anywhere really, this is the speaker you won’t be disappointed with. Get two? Insane (in a great way)! These are probably the only pair of speakers I’ll ever need and getting two for the price of one  upper end expensive portable speaker? Yes. If you’re on the fence, get two to put on both sides of that fence and the stereo will put your mind and ears at ease! 10 stars easily if I could!

      5.0 out of 5 stars Review: JBL Go 4 Portable Bluetooth Speaker
      Reviewed in the United States on July 2, 2025
      Color: SandVerified Purchase
      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.

      5.0 out of 5 stars Solid speaker all-around.
      Reviewed in the United States on February 27, 2025
      Color: BlueVerified Purchase
      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.

      I’ve been using my JBL portable Bluetooth speaker for a month now, and I couldn’t be happier. The sound quality is crisp, clear, and surprisingly powerful for its size. The bass is deep without being overwhelming, and it doesn’t distort even at high volumes.

      Pairing with my phone was instant, and the Bluetooth connection is super stable—I can walk across the room without any dropouts. The battery life is excellent (easily 10–12 hours on a single charge), and I love that it’s waterproof, making it perfect for beach days, showers, or camping.

      The build is solid and durable, and the sleek design fits in anywhere—from my kitchen to my backpack. It’s lightweight, charges quickly, and the buttons are easy to use even in low light.

      Overall, this is hands down one of the best portable speakers I’ve owned. If you're looking for quality, portability, and reliability, JBL nails it.

      I was definitely skeptical. I had read that you needed to operate it out of its own App, that it wasn’t really that loud and that it rattled. None of the above were true. It packs a mean bass for its size, connects through standard Bluetooth and it’s easy to carry anywhere. I purchased the camo version for camping. The battery life lasts around 4-6 hours; depending on your volume preference. Very durable and easy to use. The price is unbeatable for what you get. Having said all of this, don’t expect to tear walls down with the output on this guy. It puts out the right crisp volume and operates very well within a campfire vicinity. Recommended.

      5.0 out of 5 stars Small But Mighty - Perfect for Shower & Travel

      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 genuinely impressed with the JBL GO 4. For such a small speaker, the sound quality is fantastic — loud, clear, and with surprisingly punchy bass. It easily fills a room or works perfectly for outdoor use like picnics or beach days.

      The battery life is solid. I easily get around 7 hours of playtime, and it charges fairly quickly. It’s super portable, lightweight, and the design feels sturdy and durable. I also love how it connects instantly to my phone with no hassle.

      If you’re looking for a compact speaker with premium sound quality at a great price, this is it. I’m very happy with this purchase. Highly recommended!

      Muy práctica y fácil de llevar, buena duración de batería y se escucha fuerte aunque todo depende del lugar porque si es un lugar con mucho ruido donde igual te alejes un poco de ella haciendo otras actividades, si recomiendo una de sus hermanas mayores.

      5.0 out of 5 stars JBL Go 4, Excellent Little Speaker, Great Quality, Most Sound per Ounce!
      Reviewed in Canada on September 9, 2024

      I totally agree with all the 5 star reviews for this little gem of a speaker from JBL. You won't believe the sound coming out of something this small and light (6.7 oz). I think what stuck me the most was the pleasant tone and clarity of sound. It will not have deep bass like a larger speaker (physics of size), but what it does accomplish is amazing for it's size. Attractively styled in several fun colors and feels solid and well made. The silicone covers are slightly grippy and holds it in place upright or laying on it's back. Controls all work well. Battery life depends on volume and music type (bass heavy), but for light to medium volumes it will last 7-10 hours. Download the JBL app to get the most out of your Go 4 and easily allows stereo pairing (must be same model), EQ adjustment (I prefer the JBL signature sound), Auracast (mono signal though other JBL speakers at the same time with same feature) and battery level (app display only) to nearest 10%. Charges quick and cool with USB-C. I'm delighted with the sound in a Stereo pair. Audio latency is minimal and reasonable for dialogue too. As with all speakers, allow some time for break in and further sound improvement, but it is pretty good out of the box.

      An excellent fun great sounding product of which you'll want more :-)
      Happy Listening!

      **Caveat: You need a newer source device with the more recent Blue Tooth and Codecs to make it sound it's best. Older Android phones only have SBC codec (the most basic) which sounds dreadful and not the speaker's fault. I compared an older Samsung S8 to a recent S23 and the sound difference is dramatic in all aspects. Older apple devices may have better codec capabilities (?).
