Customer Ratings & Reviews

This product has great sound with deep base.It is easy to adjust the tones in the app.and it holds the battery charge all day

Great device. Costly but battery life and sound are what I was looking for. Tried a couple different speakers before I just gave in and pulled the trigger on this one. Hasn't disappointed me yet. It is on the heavy side but would recommend as the last speaker you will need to buy.

Great sound and I love how portable it is. Hold a long charge as well so you don’t have to constantly keep charging it.

The JBL speaker delivers impressive sound quality with deep bass and clear highs. Its sturdy build ensures durability, and Bluetooth connectivity makes it user-friendly. However, some users have reported occasional connectivity issues. Overall, it's a solid choice for those seeking high-quality audio.

Every time I turn this speaker on, I'm very pleased that i bought it. The sound is very clean and does not get distorted at high volumes. The bass is great but i do wish it had a little bit more. I can play music for hours even at full volume. What makes it's even greater is that I also got it on sale $100 off. Can't go wrong with this speaker 10/10

even though i returned it, it was great sound and impressive bass

Great quality sound, great highs and lows, sturdy, floats, and battery lasts enough to enjoy the outdoors.

This speaker is absolutely amazing it's worth every penny. It's so loud and the bass is so excellent

It's sound very good. especially the bass when we are playing Jass music. The battery life is enough long for mostly parties. I enjoy JBL products , in present I have had three JBL bluetoothes There are JBLFlip 5, JBL Xtreme 2 and JBL Boombox 3. The sound is soft enough not cool. I love them never be tired.

Great quality, love how the music sounds, the volume on it is very loud, also love that it’s water proof

I got it for my birthday and the sound is excellent. Every activity my JBL is with me. Park,beach,backyard and the battery last for long time. JBL A+.

Bought this after much research for travel baseball games. Sound is better vs Monster and one of the best in class for JBL. The only speaker we have heard that is louder is one of the more expensive JBL stand up speakers which are also over $100 more and not portable. Have enjoyed the waterproof, Bluetooth connectivity and the fact that it is not that heavy. The only complaint I have is the Bluetooth range. I’m not able to walk to the other side of the dugout and stay connected.

We took this boombox camping for several days and it made it through the entire trip. Others brought their own speakers and one-by-one they all ran out of juice. This speaker plays loud and also has a charge port for phones which comes in handy. Super sturdy build but it is a little heavy. Highly recommended.

The JBL Boombox 3 delivers powerful, room-filling sound with deep bass in a portable design. For its size, the sound output is impressive, and it easily fills both indoor and outdoor spaces without losing clarity. The bass is strong and punchy while staying controlled, and the mids and highs remain clear even at higher volumes. It works great for all types of music and maintains consistent sound quality no matter where it’s used. Battery life is excellent and lasts through long listening sessions without needing frequent recharging. The rugged build feels extremely durable, and the handle makes it easy to carry around. It’s perfect for outdoor use, trips, and everyday listening. Overall, the JBL Boombox 3 is a powerful and reliable portable speaker that combines loud, clean sound with long battery life and durability. It’s an excellent choice for anyone who wants big sound in a speaker that’s still easy to take anywhere.

Audiophile here, Ive listened to a great number of systems headphones and bluetooth devices including brands such as bose, klipsch, sonos, blusound etc. This speaker puts out immense sound deep bass at a large range with great battery life so far. Highly recommend for outside parties, beach etc.

Spectacular sound, you can easily take it with you and set up your party wherever you want.
