Customer Ratings & Reviews

This speaker is a fantastic improvement for JBL. I previously owned 2 Partybox 310's and bought these for the swappable battery function and auracast capability but honestly was not anticipating how much I would enjoy the improved sound quality as well. The vocals sound so much cleaner and clearer in these speakers and especially at lower volumes, it sounds significantly more balanced than the 310. I loved listening to my 310's at lower volumes from time to time, and it just sometimes was far to bass heavy for light listening, whereas with the 320 I think it is so much better to listen to. At high volumes the bass I think is just as good as my 310's and it sounds so much cleaner. At peak volumes with heavy bass you could definitely hear a good amount of distortion on my 310's and this is significantly less. I know some people have mentioned the bass is less and maybe side by side it is barely noticeable, but I have not noticed any lack of bass, and if there is, JBL is notorious for updating that kind of stuff with software updates so i'm really not concerned at all. There's the obvious perks that it gives you or that you find in online reviews but here's a few perks that they don't mention in any online reviews but I think are fantastic updates: You can turn the speaker on and off from your phone within the app, this is an underrated feature, that I promise you, when you get used to it, is so nice and convenient. It will also connect the speakers automatically from the app so no need to press any buttons on the speaker, and if you had them connected when you turned them off from your phone, it will automatically turn both on and connect them together. This is such an underrated feature. Also, there is virtually no lag with the wireless connection to multiple other speakers with video, this is huge for me because I use two of these for outdoor movies and I love that I don't need any wired connection to show a movie and they have no lag with the video. Most other brands have no lag on video if you are connected to one speaker but the minute you connect multiple wirelessly, there is a lag between the audio and video, with these that is not the case and it is amazing! The hole mount for a speaker stand on this model is smaller than the older one, which if you have owned a 310 was one of the most frustrating parts of this speaker, anytime you mounted it on a stand it was too big or too small for the standard sizes on speaker stands and would cause it to just tilt to one side or spin around super easy. They have made the hole smaller and it allows it to fit better, it's not perfect, its still a little off, but it's definitely better than the 310. Also, you have to really see the light feature in person to appreciate it, but the 310's light feature to me felt more like a gimmick whereas the 320's looks so legitimate and is just so much smoother and the customization capabilities are vast with this light feature. It also has a DJ board that you can use with your

Got this as an addition to my 310s, as I DJ a lot and wanted to get another set of speakers that ran a little longer on batteries as well as a different light show. These work! Did a party last month, and used these, and the sound was great, along with the light show. Ran them entirely on the batteries, and they held up. The light show was great as well. Wattage was great as well. The size of the room was 150x100, so having 2 of these did the job. In addition, these are a little lighter then the 310s and have bigger wheels attached, so it makes a little easier when transporting. If you're a dj and don't want to carry a lot of poundage when it comes to speakers (in addition to your other gear), these are excellent to work with and to have in your collection. Definitely recommend.

I use it at work in a very loud work environment with heavy dust. So far the sound has been amazing and hasnt worsen when I use it on max volume. Its easy to move around for the size and the volume is great for its size.

This brings life to any party. My wife uses it the most during family and friends gathering. Everyone who has listened to this speaker has nothing but praise on how good and powerful it sounds. No distortions, just pure crisp powerful sound. The lights and sound effects with the app are great. I algo got the JBL microphones and it is excellent for karaoke. It is somewhat heavy, but the handle and wheels make it easy to move around. The battery holds a charge for a very long time. I can have this on for 10-12 hours and it still has some charge left. I can also run it plugged in but I seldom do.

Great sound, didn't think i would like the light show but i did. Happy to have a rechargeable battery, and it lasted a long time on a full charge

This speaker was life saver! We were having a number of people over for a 3 day Memorial Day cook out and although we have small patio speakers out back, I needed something that would deliver a better sound. This JBL 320 did not disappoint. Brought it home while company was already there, out of the box and super quick bluetooth connectivity in less than 7 minutes. But the best part was the sound. It is hard to get deep rich bass outside in the free air like this one. I was blown away by the crystal clear highs and the backyard/neighborhood filling bass. Its quick charging meaning you can take it to a park or anywhere without electricity. I took from the patio to inside the house easily because despite its heavy sturdy build, it's easy to move because it has wheels and a pullout suitcase handle ehich help me start an immediate indoor line dance. As a DJ, I know good sound when I hear it and this is what you want for any party.

This speaker BUMPS. Wheel it around and you are the life of the party. Great battery life. Our friends borrowed it for their wedding

Purchased this JBL for our pool deck. The sound is incredible. Great bass, mid, and upper. Easy to maneuver with the handle and wheels. At 70% charge out of the box battery lasted 12 hours. Great purchase.

Great midsize speaker. Easy to transport and carry. Sound is great. Batter last a long time. Quick to charge. Microphones are easy to connect. App is good. Lights are really nice.

For whatever reason non of the Best Buy stores had the JBL Partybox 120 available to listen to, my wife said it was an omen. I purchased the 120 online, listened to it in my yard, tried to like it but it just didn’t do it for me.. Purchased the Partybox 320, and I was blown away immediately. There was no doubt which one I would keep after listening to the first song. The 120 was nice but i thiught i was missing some mids, the bass was punchy but only at volume. The 320 on the other hand has bass at low volume as well as cranked up. The difference is night and day in my opinion. The only way i can describe it is I like to feel my music and just didnt with the 120. They are both very well made, the handle on the 120 is a nice touch, the handle with wheels on the 320 is a must as it is quite a heavy speaker. To be clear JBL makes a great speaker in both the 120 and 320, if you want bass get the 320. Im not likely to listen to it at full volume but the sound quality at all levels is so much better than the 120. Is it worth $599? Well i would have waited for it to go on sale but there was an “excellent condition” open box that sealed the deal for me. Bottom line the 320 has superior sound quality over the 120 and the bass is out of this world. Cant speak to reliability but I’ve have the JBL Extreme for 7 years with no issues, battery life still great

I must say I Have to give it JBL! Truly is an Awesome speaker, No Doubt. It is Really loud. It features equalizer, light & music effects. The Battery holds up well for karaoke. Lights up bright. Would highly recommend this product for purchase, definitely worth it. Also you can link these JBL speakers with one another. Had been using one for a year now purchased this one. Have not had any issues. You can not go wrong with this one.

I loveeee this speaker so much! I am a HUGE music enthusiast and this speaker checks off all of my boxes! The sound is crisp, the lighting displays makes for a super cool vibe, and I love the touch of being able to control and adjust the settings within the JBL app. I love how portable it is. I can easily move it from room to room with now issues. If you do try and carry it, it does have to weight to it, but not a huge issue as it has a handle and wheels as well. Overall this is a great product and I am very happy with it!

Sound good battery long lasting and easy to move point to point

Let me hear ya say Ayo. AYO! Bought this to upgrade and will never go back. Big sound little package. It is a little heavy, but the wheels come in handy with that! Had a wiffle ball madness in the yard with walk up songs and the neighbors could hear it 2 streets over! Would definitely recommend. Cant wait to hook up some karaoke to it!

My son, an aspiring DJ, loves this thing. Was able to connect it easily to his Pioneer DJ controller and he has the house shaking. It is heavy, so don't plan to move it around a ton, but the wheels and handle make it relatively easy to get where it needs to be. He was able to figure out all the topside controls pretty quickly and dial in the sound just how he wanted it.

The JBL PartyBox 320 is an absolute game-changer for any party or gathering. The sound quality is phenomenal—crystal clear highs, deep bass, and powerful volume that easily fills a large space without any distortion. The dynamic light show adds an awesome visual element and syncs with the music perfectly, creating an energetic atmosphere that gets everyone dancing. What really stands out is the portability and battery life. It’s easy to move around, and the battery lasts long enough to keep the party going well into the night. Bluetooth connection is super smooth, and the added mic and guitar inputs are perfect for karaoke or jamming out. Overall, the PartyBox 320 delivers everything you'd want in a party speaker—top-tier sound, stunning lights, and reliable performance. Highly recommend for anyone who loves music and good times!

Amazing sound. The lights are really cool. Battery last along time.

Awesome Speaker. Great full sound and bass. The auracast is easy to use and works great across the other connected speakers. Really fills sound throughout the space. Battery life is great. Gets better sound when plugged in, charging. This speaker keeps the party going. I've tried other brands, but JBL nailed it as far as sound. Highly Recommend.

This is an amazing speaker! So much better than the junk mobile speaker I bought from Sam's Club, Monster brand. Love the light show. Very loud! Also the mics are top quality (sold separately). Battery life is seriously great!

This speaker is amazing!!! I'm going to have to buy a second one just to be that much more awesome. Great sound. Great bass. Great battery life. Convenient wheels and handle
