Customer Ratings & Reviews

Small yet mighty. Bought this to carry around to different areas of the house. Sound is great. Connects easily. JBL is a very good brand that lasts for years to come. Battery life is also good.

The JBL Go 4 punches way above its size. For such a compact speaker, the sound is impressively clear, with stronger bass than you’d expect from something that fits in your palm. Bluetooth connection is quick and stable, and the updated design feels sturdy enough for travel, outdoor use, or tossing in a backpack. Battery life is solid for all‑day casual listening, and the built‑in loop makes it easy to clip and go. If you want an ultra‑portable speaker that delivers real volume and quality without breaking the bank, the Go 4 is a fantastic pick.

I recently got my hands on the JBL Portable Speaker 4, and I have to say, I’m impressed. This speaker packs a punch in terms of both sound quality and portability. The audio is rich, with deep bass and clear highs, which is pretty surprising for something so compact. It's powerful enough to fill a medium-sized room, making it perfect for both indoor and outdoor use. The battery life is another highlight. I get about 12-15 hours of playtime on a single charge, depending on the volume level, which makes it ideal for day-long outings or parties. The IPX7 waterproof rating is a huge plus—I’ve taken it to the beach and by the pool without worrying about splashes or a little rain. Pairing it with other JBL speakers is easy with the JBL Connect+ feature, which lets me link up multiple speakers for an even more immersive experience. The only minor drawback is that it could take a little longer to charge fully, but the long battery life more than makes up for it. Overall, the JBL Portable Speaker 4 is worth it if you're looking for a reliable, durable, and great-sounding portable speaker. Highly recommended!

I carry this little speaker Everytime I travel or am outside doing working it's oretty loud for how small it is, stands upand is rigged and has a good amount of time in-between charges. I have bought multiple of these, and they would make a great gift.

I got this thing to ride my bike with my kid and have music playing. Mission accomplished... but that's not all! One, my kid loves it. At 15 months, she can operate this speaker, so if you can't, she's smarter than you. Let that sink in. Meanwhile I realized that if you have more than one of these you can chain them and make your own surround sound... so I'm probably getting another soon. Definitely a worthy investment. Oh and it's waterproof to like 62 meters.

Is quite loud and has good quality of sound for its price. Size and battery life are also both a plus. Ive personally used the group pairing function and it was quite intuitive, not without issues but easy enough

I recently bought the JBL Go 4 and I’m genuinely impressed. Sound: The audio is crisp and clear, especially for vocals and mids. It’s not heavy on bass, but that’s expected from such a compact speaker. Great for casual listening, podcasts, and acoustic music. Battery: Lasts about 6–7 hours at medium volume, which is more than enough for daily use. Charges quickly via USB-C. Build Quality: Very solid and portable. It feels durable, and the waterproof and dustproof design makes it perfect for outdoor use. Buttons are responsive and well-built. Overall: For the size and price, this speaker is a great deal. If you’re looking for portability and reliable quality, the JBL Go 4 won’t disappoint.

I just love this soo much !!! Sound it’s perfect and it’s pretty loud for a small speaker , size is awsome.. I can carry it in my purse!! As well as the Battery last soo long …

Excellent product , In terms of sound quality , built in features. Easy to carry , long battery life , portable , fits for every device . High level music plays with quality standards.

Price is great, sound quality is excellent and very well built. Durability is off the chart for it's size . I got 2 of them to use in stereo mode. Battery life is ok but not sure you can fit a bigger battery in this speaker.

Was extremely surprised how loud this could get and still sound great. Can definitely be enough for a pool party or a dorm room. especially for the price. Can easily have multiple speakers connected to the app and play them all at once, which is a great feature.

I bought one of these and like it so much that I bought a second. It’s easy to pair, has excellent battery life, and sounds good. Small, very portable, and seems almost indestructible.

The Bluetooth speaker by JBL - Go4, was a replacement speaker for my 2.1 wired speakers used with the PC. It takes a lot less space on my desk, eliminates lots of power and speaker wires and it sounds very clear and sharp. It can be adjusted to your liking which makes it even better. Price was very reasonable at the time of purchase. Highly recommend it and will look forward to replacing speakers on my other PCs. JBL is by far the BEST brand and a very solid brand of products when it comes to speakers and other other sound products.

JBL nailed the Portability : Performance : Cost ratio with this discreet bluetooth speaker! 9/10 The sound is surprisingly loud and full-bodied enough for a group of friends of about 8-10 persons to all share in the audio experience. The battery life is respectable for the size and the quality/durability is pretty fantastic! I highly recommend!

The sound is so good! It also has decent battery life. I love taking it on the go and perfect for a shower solo

JBL- Go 4 Portable Bluetooth Speaker-2024-Black This product is awesome. In spite of its size, it put out plenty of sound when we were out on the pontoon boat...even while the boat was running with the engine going. It has lasted since purchase, takes a little while to recharge, then lasts plenty long enough for parties/get togethers with friends. For the price, it can't be beat.

Great little speaker, the sound is plenty clear and there's a lot of power behind it's size. Very portable and getting it wet isn't a problem. It's definitely worth the price!

The JBL Go 4 is surprisingly powerful for such a tiny speaker! Super compact, waterproof, and perfect for on-the-go use. The sound is clear with punchy mids—great for podcasts, music, or outdoor use. I love the app's EQ options and easy Bluetooth pairing. Battery life is solid, though not as long as bigger models. Highly recommend if you want portability and crisp audio in one tiny box!

Wow...just...WOW! Bought this on a whim and am totally blown away! I have replaced a MUCH more expensive Bluetooth speaker used for presentations. A conference room of 15 folks can hear all around the table without any problem...and...I often present symphonic music to a very knowledgeable crowd I also use it in my woodworking shop when doing less-noisy work. Can carry it in my pocket and charge on the go with the same cable as my Samsung phone.

I really liked the size, the color, the sound and how portable it is.
