Customer Ratings & Reviews

This boombox is a beast. Shakes the walls in the house. Very loud and clear even on max volume. I have taken this into the ocean many times wit it coverd in sand. Cleans right off. Only down side is its heavy to carry long disnatces. Worth the money

I purchased the JBL bb3 for a jobsite speaker. I previously had a charge 3 and it was a good product. Moving into a new position of running work on a construction site building new houses, i needed something that could be heard over a new production jobsite and hold up to the environment. Although I returned the bb3 here is my review from having it for a week. I apologize for the format as i am on mobile. PROS: water proof, dust proof and shock proof. Should hold up to the elements quite nicely, like my charge 3 did. Sound quality is pretty good and the 96db gets pretty loud. The bass is pretty nice on the speaker as well. All around would be a great speaker for hanging out with friends or chilling at the house or outside. The handle is nice to carry and isnt heavy for the average person. CONS: I pretty much had to max out the volume so everyone in the house could hear it (rough state, no drywall, no garage door, etc.) It got decently loud it just left you wanting more. The battery claims 24 hr runtime at moderate volume (in the manual) I did not get a full 8 hr work day before it would die, mainly because it needed to be maxed out. I generally would get 6-7 hrs, and thats with pausing at lunch and not starting it up for an hour at the begginning of the workday. The speaker would roll around the floor while driving and i had to stuff sweatshirts or something to keep it still. TAKEAWAY: if this is for hanging around the house or quiet environments then the speaker is a good buy, except for the price. Tbh i think it is overpriced by a LOT. There are a decent amount of competitor speakers that get just as loud and have the same rated battery for half the price. If your a fan of Jbl and the price is no issue then sure. For my situation it left me feeling dissappointed. The battery life was one of the biggest things for me, i do not always gave access to power besides a generator, and i highly advise not charging things on a generator, you WILL ruin your product. ALTERNATIVE: after endless research i finally ended up getting an EcoxGear defender. I tested them both side by side at my house. The defender gets much louder at ~121 decibles and i have not had to max it out yet. It is also rated IP67 eaterproof dustproof as well as the bb3, and it floats. After an 8 hr work day the battery on the defender dropped 1 bar down to 4 out of 5. The sound quality is as good as if not better then the jbl, but the bass is not as rich as the bb3. Dont get me wrong the defender still has killer bass and you will not be dissapointed at ALL. Also its over 200$ cheaper then the bb3. After field testing the ECOxGear Defender, I returned the jbl bb3. I hope this helps, and like i said my situation isnt super common, but could be applied to other occupations or activities like outdoor sports/recreation.

My experience with the JBL Boombox has been outstanding. Its powerful bass and rich sound quality transformed my listening experience, making it feel like a live concert. The waterproof and durable design is perfect for outdoor adventures, despite its slightly cumbersome weight. Overall, I highly recommend the Boombox for its exceptional audio performance.

What a great kick’n speaker. I’m amazed with the sound quality and volume of this little guy. I’ve been a fan of JBL for a long time but they now stepped it up a notch again. Great job!! Excellent sound and base response with a strong long lasting battery. These go on sale every once in a while but it's worth all the money. I strongly recommend it. I love it.

I recently purchased the JBL Boombox 400, and although it's on the higher end of the price range, it's worth every penny. The sound quality is absolutely incredible, with deep bass and crisp highs that fill any space, indoors or outdoors. It’s perfect for parties, camping trips, or just lounging by the pool. The battery life is also impressive, lasting all day without needing a charge, and the durable, waterproof design makes it feel premium and built to last. The Bluetooth connectivity is seamless, and it can even charge your devices, which is a nice bonus. If you’re looking for a powerful, reliable speaker with amazing sound, the JBL Boombox 400 is an investment you won’t regret!

I'm not only impressed, I'm over-impressed. This thing is awesome. The sound is amazing. Loud and clear. Great acoustics. It is on the heavier side, but well worth the weight for the power and battery life. I had it on for about 4 hours last weekend. The volume was probably around 20%-25%. I was in my garage. When I was finished and checked the app, the battery was still at 100%. I couldn't be happier...

Compared it to Bose and Sony Similar priced speakers and even the Bigger more Expensive JBL ones and this one wins it all. Portable loud crisp clean loud and loud bass without loosing tonality or audio quality. On the heavy side but that’s expected  along battery life and you can also use it as a portable usb charger for all your Gadgets.

Great sound and perfect for just about anywhere. Highly recommend. The battery life is good as well.

I recently purchased this speaker for miscellaneous tasks. As soon as I took it out the box and turned it full blast I fell in love. The sound is superb and the bass hits. Easily my favorite speaker I have ever purchased. The speaker has a very long battery life (about 24 hours) and handles sand / water very well, it’s super easy to use and clean.

I previously purchased a different well known brand great sounding speaker, but the batterie wouldn't last for a whole work shift. I purchased this one due to the great reviews, I am not disappointed, it has great sound, long battery life, and its durable. This speaker is heavy. It will last over 4 hours at almost full volume.

This boombox is incredible, I rarely use it at more than 50%. Using party boost I connect it with my 2 jbl flip6 speakers and it fills my apartment, but I do have plans to add 2 more flip6 speakers. The bass and treble are truly amazing with boombox3,and the flip6 is equally awesome huge improvement over the older flips I owned. The only thing I miss with the new flips is they don't have a microphone so you can't use them like a speaker phone.

We love this speaker. We use it for every party and my kids even use it for their sporting events. It has a really long battery life and the bluetooth is super easy and connects well. Really good sound and it's LOUD.

Really good speaker, incredible sound quality and bass. If you are looking for a really nice sounding speaker this is it. I am super picky with sound and this one has really impressed me. Great battery life, recharges in good time. The only downside is it’s heavy so if you plan to tote it around a lot get a case with shoulder strap.

Awesome sound and great portable speaker. Battery life is worth the price.

The JBL Boombox3 has surpassed my expectations, especially as I am quite discerning about audio quality. Its dedicated tweeters, midrange drivers, subwoofer, and passive radiators collaborate seamlessly to produce a sound that outperforms speakers much larger in size. The volume can be turned up to the maximum without any loss in sound clarity. It delivers crisp highs and robust, deep bass. This speaker comes highly recommended for anyone who enjoys loud music while on the move.

I definitely love this speaker !! I had a couple different ones in the past but this one takes the 1st place on my list. Sound quality is great and the bass amazing. Every time I turn it on people find me to ask what is that and how much you pay for it. Is a 9/10 for me ,cant do 10 because battery life could be a little better and is really heavy other than that love this product.

Perfect for indoors or outdoors. Powerful sound, deep bass, and long battery life.

I love this Bluetooth speaker! We use it mostly for our little league baseball teams. I use it for walk up song and the bass is perfect! There hasn’t been a team yet that can drown out our vibes. Battery last forever it seems, and the charger also works as a standard power cord you can just use it as a 110 plug in device. The JBL app is definitely a game changer as well. You can adjust the equalizer as you need depending on the style of music or whatever you may be using the speaker for. Works well with apps like ball park DJ with no issues. Overall only complaint I have is the price 400 bucks is a lot for a speaker but it did not disappoint. The moment i started playing music we all agreed money well spent. Moral of the story if you want to be a ball park legend this is the speaker for you!

JBL really knocked it out of the park with this one. This is by far the best Bluetooth speaker on the market in its price range. It is loud clear and bassy! This speaker is so good that I bring it in the car with me and use it over my car speakers. This is an absolute buy for anybody who loves good music on the go. I have the JBL charge 5 I also have the JBL extreme 3 and this speaker blows the other ones I own out of the water. You can turn the speaker up all the way and have zero distortion and it is loud enough to fill a party indoors or outdoors. at this point, the speaker is a must have item in my life, if it broke, I would buy another one immediately.

The bass is great. Sound is amazing. Everything sounds so crisp. Great for tailgating which is the reason i got it. It is a little heavier than expected but thats how you know it’s a good speaker as well. Best battery life I’ve gotten from a portable speaker yet.
