This remarkably portable speaker delivers sound quality that genuinely surprises, pumping out clear, balanced audio with impressive bass response that holds up even at full volume. Despite fitting easily in a pocket or bag, it fills both indoor and outdoor spaces with rich sound. The IP67 waterproof construction and rugged build mean you can confidently bring it anywhere - from pool parties to hiking trails - without worry. While the 5-7 hour battery life might require occasional recharging during longer events, the speaker's intuitive app control, reliable Bluetooth connectivity, and versatile mounting options make it a trusty companion for daily adventures. The compact, modern design looks great wherever you take it, though some may need to adjust to the button placement.

Rated 5 out of 5 by from The best speaker I'd recommend purchasing I purchased this speaker in January this year and did not expect how good it was for the price! One, It is a GREAT budget speaker for people. Two, It is easy to use and carry with the size. Three, it sometimes dislikes pairing with the JBL App, but it usually occurs for the first time and may not happen again the second time you select it in the app. Fourth (and the last reason), It FLOATS! I dropped it in a murky and deep puddle and then I thought I lost it forever and then floated back up to me. No wonder It's waterproof, maybe even airproof somehow.

Rated 5 out of 5 by from Awesome customizable speaker I bought this as a gift for my niece. I chose the custom option and I have to say the custom image I uploaded came out great! The speaker also sounds really good for its size and gets plenty loud for a kid.

Rated 5 out of 5 by from JBL Go 4 - Great speaker Great product. The sound quality is very good. I haven't played it very loud yet but I am looking forward to it. Looks good, controls are easy. If you get the JBL app you can customize the sound and that's really cool. 5 stars.

Rated 5 out of 5 by from couldn't be happier LOVE IT. A friend showed me theirs and I fell in love...then I found out that it comes in the same pink as my 1980s boombox, so obviously I had to buy it. Great sound, great battery life, I dropped it and it didn't miss a beat.

Rated 5 out of 5 by from Great features! This is my first time experiencing a JBL speaker and this one is pretty cute. *There are times I think the speaker trips out & briefly pauses but idk if I’m trippin out* but overall I love it. I was shock about its audio performance -

Rated 5 out of 5 by from Excellent for its size Nice sound for such a small portable. Seems very sturdy and well built. If battery life remains good after many charge cycles then this the perfect device for lightweight travel. Had a 12 yr old Flip 2 that finally died so if this lasts like that then awesome!

Rated 5 out of 5 by from Luckiest White Elephant gift ever I got a JBL Go speaker in a Christmastime office White Elephant gift exchange. Best gift ever! Love everything about it - the size, the sound, how long a charge lasts, how easy it connects, the sound it makes when it connects, the little loop. Now I see they have new colors and you can customize it. I want another and I really don’t need one. Someone is getting this for Christmas.

Rated 5 out of 5 by from Cranks Great little speaker. Don’t let the size fool you! This little sucker punches out some high quality sound and the price is right

Rated 5 out of 5 by from Great speaker, even better with 2 in stereo mode I bought a Go 4 two months ago for the purpose of having a small portable speaker with good sound for traveling. I liked it for having some decent music in my hotel room. Then I bought a second Go 4 so I could use them together in stereo mode and I really love them now. I used them together on another trip and for me the music is even better in stereo mode.

Rated 5 out of 5 by from Small but powerful! Magnificent bass in a small package. We enjoy it poolside. Traveling is a great advantage due to the small size. I would recommend it. In this case less is more. The briighter the color , the easier to find.

Rated 5 out of 5 by from Beautiful design. I had a Go3 for 8 years gets abused as my shower speaker. It’s not holding its charge as well so I saw this refurbished Go4 at a great price and it’s awesome! Great beautiful deep purple color with the same deep sound that is luscious. Love it. Let’s see how it goes.
