Customer Ratings & Reviews

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

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!!

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!

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!

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!

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!

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.

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.

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.

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

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

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

We got the JBL PartyBox 310 and it turned our house into a full Filipino karaoke bar! The sound is so clear, even my high notes (and low notes) sound good. lol! Perfect for family gatherings, birthdays, BBQ nights, and those random “mag-videoke ta!” moments. Strong bass, clear vocals, and super loud. Our neighbors definitely know we’re Filipino now. Highly recommended!

I recently purchased the JBL PartyBox 320 from Best Buy, and I’m absolutely blown away by its performance! The sound quality is incredible—deep, punchy bass, crisp highs, and a powerful volume that fills any space. The built-in light show adds a fun party vibe, and the Bluetooth connectivity works flawlessly. Battery life is impressive too, making it perfect for outdoor gatherings. While my first unit arrived with some damage but the Best Buy’s customer service team handled the issue professionally and without hassle. They quickly arranged a replacement, and the process was smooth and efficient. The staff was courteous and ensured I got a brand-new, flawless unit ASAP. For anyone looking for a portable, high-quality party speaker, the JBL PartyBox 320 is worth every penny. And shopping at Best Buy gave me peace of mind—their commitment to customer satisfaction is top-notch! Highly recommend both the product and the retailer!

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.

I couldn’t be happier with the JBL 320 speakers. The sound quality is incredible—crisp highs, punchy bass, and clear mids. Whether I’m listening to music, watching movies, or gaming, these speakers consistently deliver immersive audio that fills the room. The build quality is also top-notch. The sleek design fits perfectly in my living room, and the setup was a breeze. They’re versatile and pair seamlessly with all my devices. JBL has once again proven why they’re a leader in audio technology. Highly recommend these speakers for anyone who values premium sound and style. Worth every penny! Swappable battery is a plus!

I got it on sale, so that’s a big plus. I love the sound quality and the light show this JBL PartyBox has. Additionally, the JBL app allows for an even better experience. I use this speaker almost every day so it’s safe to say it was worth it every penny.

When I tell you i made the best decision yet. I wanted a good speaker for my july 4th bbq and this speaker did not disappoint. Its exactly as pictured. The sound has great clarity. It comes with a handle so you can roll it like luggage lol instead of heavy lifting. The sound made seam like i had a dj in my backyard thats how good it sounds. It also comes with a app easy to work the speaker without getting up to do so which is a plus for me. The highlight was when it got dark my husband was like a little kid enjoying the different light features and the different beat sounds you can add like your a real dj. So go run and buy it.

Great sound, it worked awesome for an open park baby shower. Loved the different light shows. Battery didn’t last as much as I expected but still a great speaker.

Despite never thinking I'd say this, I recently purchased the Sony XV900, believing it was the best sound I could afford. I discovered that I needed a smaller, more portable speaker. As I do for ALL things electronic, I walked right into Best Buy to buy a smaller speaker. I felt I would have to sacrifice sound quality and bass. Well that wasn't true at all! After the in-store demo, I purchased the JBL PartyBox Stage 320. My jaw dropped when I heard the JBL PartyBox Stage 320 sound quality! The lows hit so hard! The sound is well balanced. I am extremely impressed! A huge shout out to Best Buy for always offering the BEST electronics. I guess it's all in the name, BEST BUY!
