Customer Ratings & Reviews

This is a phenomenal speaker. It completely fills the room and has a massive base. The new firmware update completely gave it a new balanced sound. I am very satisfied with the battery level. I have the JBL easy sing mics that connect to it via type C with no issues. I also have the JBL Boombox 3 and this one is clearly the winner in decibal sound and weight as it is lighter. You won't regret spending the money and this speaker. The JBL Boombox 4 is a masterpiece of portable sound.

I’m really happy with this JBL speaker. The sound is clear, has great bass, and gets plenty loud without sounding distorted. It’s easy to connect, feels solid, and the battery life has been great so far. Perfect for around the house, outside, or taking on the go. Definitely recommend it.

I recently purchased a JBL speaker, and overall I’m really impressed with the quality. The sound is loud, clear, and has strong bass without sounding distorted, even at higher volumes. It’s perfect for both indoor use and outdoor settings. One thing I really like is the battery life—it lasts several hours on a single charge, which makes it great for trips, gatherings, or just moving around the house. The Bluetooth connection is also quick and stable, with no annoying dropouts. The design is another plus. It’s durable, easy to carry, and waterproof which gives peace of mind around water. If I had to point out a downside, it would be that some models can be a little pricey, but you definitely get what you pay for in terms of sound and build quality. Overall A reliable, high-quality speaker that delivers great sound and durability. Definitely worth considering if you want a portable speaker that performs well.

The JBL Boombox 4 from JBL is an absolute powerhouse. The sound is loud, clear, and packed with deep bass that easily fills any space. Battery life is impressive, lasting all day without a problem. It’s also rugged and waterproof, making it perfect for outdoor use. If you want premium sound and durability, this speaker is 100% worth it. Highly recommended!

The JBL Boombox 4 is one of the best portable speakers you can get if you want powerful, room-filling sound with deep bass, extremely long battery life (over a full day), and rugged waterproof build quality. It’s perfect for parties, outdoor use, or even loud gaming setups, delivering clean audio even at high volumes. The only real downsides are its heavy size, high price, and lack of an AUX port, but overall it’s about as close to a top-tier “all-in-one” speaker as you’ll find.

As soon as I got one I had to get another, very loud and compact and best of all music you can feel! Awesome battery life and sound that is consistent with the JBL name. I had heard of software issues earlier on but I can tell you with the latest versions they solved it. Auracast makes pairing super easy and they sound amazing. One is great and plenty for most gatherings and bbq’s, trips to the beach and park. Two you can throw a party with!

Amazing wireless boombox. The battery life is phenomenal and the bass sounds very good. Extremely satisfied with my purchase.

very good speaker for houses parties or to have in your room. loud but good quality deep bass and easy to control volume

I recommend this equipment 100%, for me it fulfills everything I like of very good quality, it sounds at a spectacular level, and its charge lasts as they say in their information, from the heart who can buy this horn will not regret it

Wow, this thing is loud. The bass is amazing. Great upgrade from the boombox three. I definitely recommend it.

Love it! It’s not heavy at all. It has a good bass sound. But i love that it has an equalizer on the app

This speaker was not what I expected, in the best of ways of course. Its loud, yes, but at the right amount. Depending on the environment, it can either burst your ears in a small room, or you can hear it from the next block over. With the Bass Boost feature, you can not only hear the music, but FEEL the sound waves. And last but not least, Auracast, i have the Charge 6 and Clip 5 which also have Auracast and can easily sync up my music in my home or at gatherings and you can walk into the next room with a synced speaker with the music seemlessly following you. For the price, this product exceeded my expectations. If you’re a JBL fanatic, this ones a no brainer if you like taking your music on the go.

I got this $100 off and it was well worth it. I have loved my boombox 3, but the 4 takes it to a totally different level concerning loudness and bass with the same or better clarity because of the enhanced EQ on the BB4. It is also noticeably lighter as well. It literally gets twice as loud and the bass capabilities aren’t even comparable. I have every boombox and i would say this one is the biggest upgrade over the previous generation. I can also connect this with my Partybox 520 out in the yard with auracast and the batteries are interchangeable which is great. People complaining about the price are the people that don’t know much about modern tech. The lightness and portability of a speaker that sounds the way the BB4 does shouldn’t exist. The BB4 is well worth the price. Get one. You won’t regret it. I use “Rock” Eq on my iPhone combined with a custom EQ curve on the JbL app and prefer deep bass mode for the best sound.

Finally... I can jam with the subcompact benefits of a real fine quality boombox. The audio is crisp. There is some preset audio contols and for those who can do custom it has it. I love it! Battery life is good the durability is good. It doesnt rattle. Positioning is important and i wish they made a little better cover for it but it did have a cover so no problems from me.

This JBL Boom 4 is the party starter ! Bass is thumping, sound is clear, and battery life is lit – 24 hours of nonstop jamz! Waterproof, portable, and BOOMING loud. Perfect for beach vibes or backyard hangs

I just received my JBL Boombox 4 through UPS in just 3 business days. Not only was my product shipped to me fast but the box was much bigger than I expected. After testing the sound on this boombox I realized this boombox sounded a lot more like a kicker I had installed in a car. This boombox is off da wall, Seriously, all these comparisons they advertise on YouTube are garbage. No more comparing because if you ain’t got JBL, you ain’t got a boombox. Not only does this boombox have superior sound, but it has bass that bumps just as loud as my JBL 1300 & it’s portable. You got to get this boombox, there is nothing but pure bass & you get every dollars worth & even more for what you bargain for. JBL4LIFE.

This speaker has decent power. Sounds decent battery life. If you played a full power last about 5 hours If you are conservative with the power could last longer overall, an ok product dust proof water resistant, convenient to move around, if you are interested in moving a speaker around, this will be a great product.

“The JBL Boombox 4 Portable Waterproof Speaker delivers incredible bass, super powerful sound, and long-lasting battery life. Plus, the design is beautiful, and its water resistance makes all the difference for use anywhere!”

Bought this as a gift for family - they love it. Produces great sound.

Amazing sound quality and battery life. Don’t hesitate to demo it. It is a keeper. Coming from an extreme 2 = no comparison. Very livhtweight for the amount of distortion free output
