Customer Ratings & Reviews

This speaker is so amazing its loud and it has a lot of bass and its not that heavy its comes with me whenever i need it and the battery life is amazing im glad i made a choice to pick this one instead of all the other ones

I am very happy with the JBL PartyBox 320. I bought it for family parties indoor and outdoor. The sound quality is amazing! If you like bass, you will definitely like this speaker. Bass can be adjusted too, so if you want to turn it down, it’s an option. The wheels and telescopic handle is very useful. For moving it around. I’ve had it for about a month now, and I have had zero issues.

LOVE the Party Box 320!!! I’ve been eyeing the Party Boxes up for years and finally decided to pull the trigger. I am so glad I did! From using at parties and picnics, to playing walk-up songs for my son’s little league team, to playing music and sounds for sleep…This product does it all, and does it all with high quality. Clear crisp highs to deep theater-like bass with great boom and punch when you want or need it! The app works great and you can choose from several different lighting patterns and colors, as well as running just the leds or just the strobes. I use this with my iPhone and have no issues operating it. The battery life is as advertised if not a little better, and when using it plugged in the speaker boosts its audio a bit. I know they are on the pricey side but you definitely get what you pay for!

These speakers are BEASTS! Heavy, solid, nicely built. The sound is phenomenal and the bass, which you can feel, is great! I bought two and paired them through the JBL app. They’re on wheels too, so moving them around is easy. I dont regret my purchase and highly recommend if you are looking for a great speaker!

This thing sounds great and connects to everything. The battery lasts longer than you will and it it LOUD!

I waited more than 6 months to try this speaker out and give a review to be as helpful as possible. I use it at home and also for little league walk up songs. The speaker is loud, sounds great, and is a lot of fun. It’s portable and easy to transport (for me at least). The battery lasts several hours which is helpful during games and the mics I purchased separately sound great also. I do recommend it!

Me gusta su sonido sus luces su forma de llevar a todos lados que apesar de ser un producto grande con sus ruedas hace mas facil su traslado de un lugar a otro

Excellent Sounds quality with loud bass, battery lasts many hours,

TGM here with an honest and concise review. Simply put, if you're seeking exceptional sound quality, mobility (untethered from AC power), and hours of fantastic audio, stop reading and get yourself this speaker right now. I can't find a single negative aspect to mention, except perhaps that it could be a bit more affordable?

If you're looking for strong base go with the 320 no disappointment super crisp clear and you can adjust the EQ audio to whatever you desire whatever type of music you like I first bought the 120 but the 120 sounds a little muffled compared to the 320 to 320 is definitely worth it

Love,love, love this speaker! I was very hesitant to purchase it because of the price, but it is worth every penny! It is loud enough for an outdoor party and we really enjoyed it for good Friday! I feel like I want to buy another to blow out the entire block lol, might not be a good idea my neighbors might complain lol but Its my new fav! JBL never let's you down! I love that it's on wheels and that I can use the battery or plug to listen to the music. This is the best speaker I have ever had and now I can get rid off the smaller non JBL speakers lol. Don't hesistate to buy it if you want a good quality bass booster playing speaker. You can also hook your microphone or guitar to it as well, this speaker is amazing I could go on and on about it lol

Speaker has great sound with a good ampunt of base for this size speaker system. Portability is better than expect for the size and weight. Great run time on a single battery with the option to change it out.

Excellent speaker. Great sound. Get loud enough to hear through the whole house. The highschool had my son bring it to a fundraiser in the gym. You can charge it and play it for hours. Has a handle to wheel around. It is big and heavy.

It's great indoor and outdoor. The sound does not dissipate outdoor. It is heavy so having the wheels and the adjustable handles helped with the portability. Good light show. Using the app provides you more options than what's available on the control panel. Am happy with my purchase.

This speaker provides the loudness, clarity, and deep bass that I am looking for. It is phenomenal for house gatherings where you are looking for some dance music for your guests. I also take this to the beach, parks, mountains, and just about everywhere I go thanks to the portable battery. I’m highly satisfied with JBL sounds.

So I’ve been using the JBL [Model Name] for a little while now, and honestly, I’m pretty impressed. The sound quality is super clear, with enough bass to make it feel way bigger than it actually is. I wasn’t expecting it to get this loud, but it totally holds up, even outdoors.

I took this speaker out for a real test on New Year's Eve ,wheeled it all around downtown San Diego for hours, playing music the whole night. It absolutely bumps. The bass is deep and powerful, and it gets seriously loud without distorting much, easily filling open areas with sound. Battery life held up great through the entire evening, even with the volume cranked and lights going. JBL claims up to 18 hours, but real-world at party levels you're looking at less, and it still lasted the night for me no problem. We got hit with one of those rare San Diego downpours, and I'm not recommending you soak it on purpose, but it survived getting pretty wet and is still working perfectly. It's IPX4 splash-proof, so light rain or splashes are fine, but yeah, it handled more than expected. The light show is really cool, it synced to the music with swirling patterns, strobes, and starry effects that add a lot to the vibe. Best part is how discreet it can be: the design isn't super flashy when off, and you can tuck it under a table or in a corner, and people won't even spot where the sound is coming from until it hits. I wonder what two of these paired together would sound like, it supports stereo pairing or linking multiple via the app for even bigger sound, and I'm tempted. The JBL PartyBox app is pretty cool too. You can fully customize the light shows, add stutter effects, echoes, or other DJ-style tweaks to the audio in real time. It's a nice extra for messing around. Overall, if you're looking for a portable party speaker with wheels, solid battery, tough build, and fun features, this one's a beast. Highly recommend.

YOU MUST HAVE! This is no weak speaker, you can hear it very clearly for a good 100yds or more. Great speaker. Portible, lasts along time 15hrs we had at the lake still had a quarter bar. And you can hook up a mic and a guitar it has a built in amp. Could make it a busking unit if needed.

Excellent sound, clear and powerful, lights are awesome and better than previous models on my opinion, get your and be your own judge, you won't be disappointed,,

I love it, sound quality is awesome , and reallly really loud just how i like it, you can mess with sound more on the app i love that ! Not to big not to small think its perfect size i also love that the microphone settings have nobs on the top now thats convientient
