Customer Ratings & Reviews

This product is the single best sound system I've ever owned I used it in my house and you can go as quiet as you need to or you can rattle the walls which I normally do I love the fact that you can hook microphones I can hook it to the tv YouTube have your own karaoke party I love that I can hook my guitar to it I can hook my electric drum set to it and I really love that if I get my friends over they can bring some of their equipment and I can hook to theirs and we can have speakers set up all over the house I love the light show pretty cool when you do it manually with the beat you can change the light change the color with the beats and overall I haven't had one issue or no popping or cracking sounds or and I play my music pretty loud so it's a whole it holds up I love the fact that it just takes a battery and it's interchangeable so you can get more if you out in the middle of nowhere and you still want to party but normally I just keep it in my house and I keep it plugged into the wall so you get 100% of its power instead of 70 but even at 70%. It's still rocks I have in my truck another type of system that also has a j and a l in the title but they are really expensive the JBL products especially the stagemaster 320 has very exceptional sound quality even at high volume and for the price you just can't beat it I would highly recommend this that anybody that's looking for high quality Loud Entertainment and possibly putting on shows on a budget I haven't really found any dislikes except for one tiny one the fact that you can't cut the top panel lights off cuz when it's in my bedroom and I'm trying to sleep and I cut the main light show off you still got the glow on top of the lights from the top panel but that's no big deal I just put a towel over it or a shirt I do wish it came with its own remote because that's kind of a hassle for anybody who only has one like phone or one iPad to hook to it because a lot of music Outlets say like YouTube when you back out to go to the remote YouTube shuts off cuz you can't play in the background I have multiple devices so I can have one for the remote and then one for whether I have it on YouTube music Sirius Amazon or whoever but having its own dedicated remote would be a nice feature and even if they came out with one that I could purchase I would still purchase it cuz it's just convenient also I love the portability of it I mean it's a little heavy but that's good the heavier it is that means the better it is when it comes to speakers but the fact that it's got wheels and a suitcase type extendable handle that makes it really easy to roll around and actually just notice now when I took the picture the tires are on it I have white letters that's awesome because I run a shop and I do a lot of tires so it's just something the little things just go to show you that they really care

The JBL PartyBox 320 is amazing! Super easy to use, connects instantly, and the sound is powerful with great bass. The lights add so much fun, and the battery lasts a long time. Perfect for parties or just hanging out, highly recommend!

I really like the size, the sound, and overall the mobility of it to be used anywhere without having to be plugged in. I enjoy being able to take it anywhere like outdoor activities and also works perfectly for get togethers. Battery does last as described and the Bluetooth connection is really great. Does not cut off or have Bluetooth issues. Definitely worth the price. I had to get a second one

Many reviews I read online mentioned the battery life was not great. I disagree! I used it at the pool over the weekend for 5 hours each day and a couple of hours one evening. When I came home from the weekend I still had 40% battery life left. This was at maybe 30-40% volume unless one of those songs that just require max volume came on. I also turned off the party lights all day and the bass boost most of the time at the pool. I did buy an extra battery online for $49 but did not need it. I still feel the extra battery is a must so the party never dies. It was great engineering and design to make the PartyBox 320 with a removable battery! When my JBL Boombox 3 died, the party was over. Sound quality is fantastic as with all my JBL speakers. Even at the loudest volume there is no distortion. I like LOUD music but not at the expense of sound quality. Another person at the pool had a Turtlebox Grande and it was super loud but had tinny highs and not near the base of the JBL. The PartyBox is NOT light but it does have wheels and a telescoping handle for easy movement. I purchased a great cover for the PartyBox from another online seller that is fantastic and includes pockets on both sides and protection for the speaker when zipped up for transport. I would definitely buy the PartyBox 320 again and for the $499 4th of July price it was worth every penny. It’s not as portable as my JBL Boombox 3 I replaced but you won’t regret the big sound. As with most purchases, I did buy the 4 year accidental protection and am hoping I don’t need it but it’s great peace of mind on a 5 or 600 dollar speaker. Go ahead and buy the JBL wireless microphones! They work seamlessly with this unit and were a lot of fun for karaoke. I am very happy with my purchase and would highly recommend. Just buy it!

I love this speaker! I bought this speaker for my sons birthday party & it was a complete hit! I got so many compliments & questions about getting one for themselves!!! When I tell you this speaker brings the club right to your home, the bass delivers a powerful thump! Then add the bass extender to really bring down the house, my walls literally vibrate from the bass! I love the fact that it's wireless with an retractable handle & wheels to literally transport anywhere! The battery life is insane, at full charge it really does last ALL DAY!!! I've taken this speaker to the beach for parties & events, & it doesn't disappoint the sound range is incredible! I live in Hawaii so rain is sometimes unexpected, the speaker has gotten rained on & still works like new the day I purchased it! This speaker definitely exceeded my expectations, if you're on the fence on speakers GET THE JBL!!! It's worth every penny!!

Certainly a great choice if you’re looking for a powerful portable speaker. A major level up from your standard portable Bluetooth speaker. The sound quality is awesome and the bass hits. The RGB lights are a cool feature as well. Tons of customization with the sound and light display through the app. The battery life is also great.

I bought this speaker for backyard parties and beach days, and it’s been a solid performer. The sound is surprisingly full and loud for its size — bass hits decently without distorting at higher volumes, and the mids and highs are clear enough for music, podcasts, or even taking calls. What really stands out are the glowing LED lights in that infinity/figure-8 shape. They look super cool at night and really add to the vibe. The lights are bright, have multiple modes, and sync nicely with the music. Kids and adults both love it. Battery life has been excellent so far — easily lasts through a full afternoon/evening party on a single charge. It’s also pretty rugged and splash-resistant, which is perfect since it’s been outside a lot. The only minor downside is that it can get a little heavy after carrying it around for a while, but that’s expected with good battery life and decent sound. Overall, for the price, this is a fun, loud, good-looking portable speaker that delivers more than I expected. Highly recommend if you want something that looks as good as it sounds at your next gathering!

Absolutely love this speaker. If you’re heavily debating on it but scared by the cost, just go for it I promise you won’t regret it. Has been the perfect speaker for my family whether it’s indoors, outdoors, BBQ’s, lake days, camping, and of course karaoke nights, etc. this thing is POWERFUL and has great sound quality. I originally bought the 120 and loved it so much I upgraded to the 320 and gave the 120 to my parents. (Both pictures 120 on the left 320 on the right) absolutely love having the wheels it makes it super portable. JBL is the best

Owning the JBL 320 has genuinely been a game-changer for me. The first thing that blew me away was the battery life – it feels like it just keeps going, so I never stress about it dying in the middle of a party or a get‑together. I can roll it out, turn it on, and forget about charging for hours. I also really appreciate how solid and sturdy the wheels are. When I’m dragging it across my driveway, through the house, or over uneven sidewalks, it never feels wobbly or cheap. It gives me the confidence to actually move it around instead of parking it in one spot and leaving it there. Putting it together and getting it running was almost effortless. I’m not particularly handy, but the assembly was extremely easy and straightforward, and I was up and playing music in minutes. That simplicity made the whole experience feel welcoming rather than frustrating. The sound quality is simply fantastic. Every time I turn it on, I’m reminded why I love it: the music comes through rich, clear, and full, with bass that hits without drowning everything else out. Whether I’m hosting people or just listening on my own, it makes every playlist feel bigger and more exciting.

Bought one back in April and loved it so much I bought a 2nd for stereo pairing. They work absolutely flawlessly. They sound great for what they are and they are LOUD! I am using them as the left and right channels for a portable outdoor theater setup and I have never been able to get them up to full volume even outdoors because they are so ridiculously loud, but I have cranked them loud enough during the t-rex scene in Jurassic Park that my camping neighbors who were about a half mile away in a heavily forested mountain area in Colorado could hear hear the roars clear as day, which must have been pretty concerning at first. If you are looking for an outdoor theater setup, this is the way. As for music indoors, I have about $8k in sonos speakers throughout my main floor, which obviously sound better and more detailed, but collectively they cannot reach half the volume of just one of my JBLs. They are honestly complete overkill, as my sonos setup is plenty loud and anything louder starts to get painful, so they're set up in my basement for projector movies and karaoke parties, and they THUMP. Outdoor music is where they especially shine tho. I have brought them to tailgating events, used them in a friend's back yard as part of a complete DJ setup, BBQs, camping, lake day parties, etc. I have maybe had a max of 30 people at these events, but they could very very easily bring enough volume to a party of 100-120. They seem to go on sale quite a bit, as they are at the time I am writing this, so if you see 'em on sale, grab 'em. If you can wait until the next time they're on sale, it probably won't be a long wait, but they are easily worth the full retail price, so you really can't go wrong!

You will be blown away by the sound, battery life, volume, and build quality. This speaker was expensive but well worth it. I enjoy it a lot and can't wait for summer pool parties and beach parties . If you can afford it get it or save up for it. I got this one and the Xtreme 4 jus6t because they change batteries and I can change the batteries if they go bad down the road also I can take the xtream 4 to places the 320 can go

Very much worth the price. The battery lasts a very long time, I still haven't needed to charge it from out of the box and I have used it many times for long periods of time. The audio is very clear and rich in quality. The speaker can get extremely loud while maintaining quality. It is easy to transport to places and the suitcase handle really solidified that for me. The DJ costomization options are plentiful in variety, and the on board AI and bass boost are really a cherry on top. What a great product, I will probably never need a new speaker in my life.

We love this speaker. It sounds great, battery last a good while, and we can take it along with us. We live on a small farm and take it outside often and can hear it while we work.

My wife has been using it a couple of times a week for group health events. It fills a good sized room with vibrant sound. It easy to position and then put back into storage with the built-in wheels. We bought the PB320 wireless mics and they pair easily through the include Bluetooth adapter. We haved used them to mic up instruments and voices; all sounding great even at volume. We just added 2 JBL Flip speakers that have an amazing amount of sound for their handheld size. The JBL app adds them as L and R and by simply pushing the triangle .and then you control the system of 3 speakers with the JBL app and the volume buttons on your phone. Even non-techies will find the JBL system easy to start and grow

I bought a sony and returned it for this. I could've been more happier. This thing is very loud for its size. The bass is insane. I love the swappable battery and the light shows

Works pretty good and it gets pretty loud. Decided to go with the 320 since it’s powerful enough and portable to take on family gatherings. Doing karaoke with the JBL microphones works great, no static and clear sound. Overall I would recommend this speaker.

Easy to set up and connect. Initial charging didn't take that long and we used it for several hours without needing to charge. The sound quality is excellent and the light show feature is very cool. I paired with the newer JBL bluetooth cordless mics and the quality is excellent. I definitely recommend!

Excellent I was widely pleased, it is versatile for large events for small it has great sound power, in general it is very good. A little heavy but includes wheels. The battery lasts approximately 5 continuous hours depending on my use.

Outstanding speaker. 7 hours of play time at 80% and still had 56% battery life. Great base. And gets louder when plugged in. JBL rocks!

Great speaker, purchased Jbl Party box speaker 320 during black friday. Long battery life, light show is a nice touch. Bluetooth connectivity is fast. I found that for best bass sound place near corner or close to a wall. The only con found, you will want more sound or you'll want to upgrade to the next step up.
