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.

You guys... if you are looking for a compact speaker if you are on the go, hiking, backpacking and such, this will not disappoint. I've used the JBL Go 3 for a few years already on backpacking trips, and have been more than pleased with the performance of this one. This Go 4 has upped the sound quality, battery life, and even a few grams less in weight over the Go 3!! So, if you are on the fence of just owning one, or upgrading from a previous version, this is a solid choice!! Great at home also, for chores outdoors, or in the house, or even singing in the shower, it's just worth it to have if your phone speakers are not enough! You will not be sad that you own one.

This speaker really has all the essentials and surpasses and expectations I had for it. I'm honestly pleasantly surprised. It packs enough bass and functionality for the price while not breaking the bank. I haven't seen how durable it is yet but I have yet to learn. So far it pairs well, sounds great, is very useful and is very versatile! It is very easy to set up and I enjoyed the quality of the material used

If you’re looking for a compact, reliable, and surprisingly powerful speaker, the mini JBL portable speaker is a fantastic choice. Designed for people on the go, these speakers combine portability with sound quality, offering features that punch well above their weight. Build and Design The mini JBL portable speaker is lightweight and fits comfortably in your hand. Its rugged, waterproof design (IPX7 rating) makes it perfect for poolside parties, beach outings, or hiking trips. The durable fabric and rubberized housing give you the confidence that it can withstand accidental drops and splashes. Plus, the carabiner clip is a thoughtful touch for easy attachment to backpacks or belts. Sound Quality Despite its size, the sound output is impressively rich. The bass is punchy without overwhelming the mids and highs, ensuring clarity for vocals and instruments. It’s perfect for small gatherings or personal use, but don’t expect it to replace a full-fledged sound system for large spaces. That said, the audio remains distortion-free even at higher volumes—a testament to JBL's engineering. Stereo Sync Feature One of the standout features is the ability to pair two mini JBL speakers for stereo sound. The syncing process is straightforward—just press a button on each speaker, and they’ll link seamlessly. The stereo mode elevates the listening experience by adding depth and immersion, making it ideal for watching movies, gaming, or simply enjoying your favorite tunes with a friend. Battery Life The battery life is another highlight, offering up to 10 hours of playtime on a single charge. It uses USB-C for charging, which is both fast and convenient. Real-world usage may vary depending on the volume level, but it consistently delivers enough power to last through a day of moderate use. Connectivity Bluetooth pairing is quick and stable, with a range of up to 33 feet. The connection remains strong even through walls, making it easy to move around without losing the signal. Additionally, the speaker supports voice assistant integration, allowing you to control music or check the weather with ease. Value for Money Priced reasonably, the mini JBL portable speaker offers excellent value. Its combination of portability, sound quality, and features like stereo sync and waterproofing makes it a versatile companion for any lifestyle. Final Verdict The mini JBL portable speaker proves that big things come in small packages. Whether you’re relaxing at home, hosting a casual get-together, or adventuring outdoors, this speaker delivers. Its stereo syncing capability is the icing on the cake, allowing you to double the sound for an unbeatable experience. Highly recommended for anyone seeking a portable speaker that doesn’t compromise on quality. Rating: 4.8/5 Pros: Compact, waterproof, stereo sync, excellent sound quality. Cons: Limited bass for larger spaces. Perfect for single rooms though!

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 (?).

Suena muy bien, es ligera, te cabe en la bolsa del pantalón o sueter. Se escucha muy alto, la traía mientras trotaba y se escuchaba alto a pesar del que hacía demasiado ruido por el viento. Muy bien y resistente para el precio. Me encanto. 💖

A caixinha chegou antes do natal, o que considero uma entrega muito ágil! Ela apesar de pequena e compacta tem um som muito agradável e alto, ainda não experimentei na rua, mas dentro de casa a altura e a qualidade é bem satisfatória! Ainda não sei a duração, mas no geral eu recomendo a compra!

Som com uma qualidade ótima e muito prática também bateria que dura muito tempo. Super recomendo

Muy buena, se escucha bien y es fácil de transportar
