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.

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.

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!

This thing is an absolute BEAST for its size! And i love that i will have it forever because of the battery replacement feature. I tested it’s waterproof capability by having it float in my bathtub and dunking it under water and it passed the test! 

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!

I’m very highly satisfied with my JBL Boombox 4. I bought it Open-Box from Best Buy, and started bumping the moment I took it out of the box in my car. The sound quality is immaculate, as I use it everyday at work in a very large environment. People literally hear it playing across the building and some have asked me where to get it. It’s well worth the price technology and audio wise and a substantial upgrade from the JBL Xtreme 2 I formerly had. Test one out for yourself. I’m playing my favorite music on it now as I type this. Five stars all the way.

This portable speaker is REdonkulous!! The sound quality is unbelievable even at high volume. It has 2 extra diffrent bass options that takes it to another level. The bass quality is deep and yet eloquent. It a speaker that you have to actually try it out to believe and understand that craftmanship they put into it. GREAT JOB JBL!!

I like the battery life and the amount of Bass it has. I owned the boombox 3 and so far the 4 is better.

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

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

This has amazing sound quality at a great price. We can hear it all throughout the house during our daily chores and its great for parties

This speaker has great bass and its perfect for outdoors or like the beach, the bass boost mode makes it perfect for listening at lower volumes too.

Es una magnífica bocina con gran poder y mucha duración en su batería, sin duda mejor que las versiones anteriores.

I'm happy with this new update and I'm taking it everywhere with me

This boombox packs a punch of base sound. The sound quality is very good. I really like the app and all the different sound settings for the speaker. The handle is perfect for portability and the designs of the speaker is looks better than any other speaker on the market. Lastly, the Aura cast feature that allows you to be able to connect other compatible speakers is an awesome feature. My overall opinion of this JBL Boombox 4 is that it is a great product.

Nice, comfortable, light to lifting, fancy and easy to use
