Customer Ratings & Reviews

Very impressive, deep, crisp, clean sound. Solid build quality. The bass will surprise you. It’s louder when plugged into AC power, but still plenty of bump in the tank on battery power. I’ve never once had an issue with battery life - even when intentionally trying to run it dead, it just kept on playing (until I finally gave up and went to bed). I honestly have no idea how long it lasts; at 50% volume [just enough to feel it but not enough to force everyone to yell over it] it will last a full funday, guaranteed. I have a rather picky ear [audiophile] so over the past 3 years I’ve tried at least 17 name brand portable bluetooth speakers in the $500-1K range and, my final judgment is this -- aside from an $1100 Soundboks3, this Partybox310 is the biggest [and loudest] bang for your buck. Hands down. (Mine was $430 on sale in 2020) If you can afford it, I also recommend buying a pair. Two of these running in TWS/Stereo mode sound incredible for a battery powered set priced at a grand. (Or even less when marked down on sale - hold out for Black Friday and order online) A few complaints to mention: 1.) It could be more rugged/durable. The casing is hard plastic and likely to scratch easy. Bigger rubber corner bumpers or feet would’ve gone a long way. It also likes to roll around in the back of the Escalade unless deliberately secured. Trust me, this big brute can do some damage if you take a couple hard turns. -__- 2.) The previous model (Partybox300) had a third tweeter allowing it to play in stereo mode when turned horizontal. This new 310 model does NOT have the third tweeter and thus, is mono-only. You would have to use a second 310 unit connected in TWS (True Wireless Stereo) mode in order to achieve stereo L+R sound. Or, use Line-in and an equalizer/amp to separate the L and R channels. It still sounds great in MONO, but who wouldn’t prefer an option for STEREO… plus, this speaker is just big enough that I wouldn’t want to always lug around 2 of them, and small enough to make one speaker well worth it’s while. Note: The 3.5mm line-out will work with a second speaker when playing via bluetooth input. (both in mono) (yes, even on battery) 3.) A small built-in storage slot for the power cord would’ve warranted significant bonus points. I always worry it will get lost or forgotten. I’m planning on buying one of the JBL “transport bags” to keep everything better organized and protected. (JBLPARTYBOX200300-BAG) 4.) I expected the BASS and TREBLE buttons on the top of the unit would adjust the sound when playing via bluetooth or line-in. WRONG. Those buttons on the top only work with the MIC/Guitar 1/4 inch inputs on the back. (I should’ve known with the ECHO button right beside them…) Oh, and the app is alright. It’s good. Definitely better than Sony’s garbage setup. All said and done, I would highly recommend the JBL Partybox 310 to anyone looking for a “whatasized” portable speaker, and vouch that it is worth it’s price tag. If you’re on the fence, go buy one. You can always return it… but I bet you won’t. ;) I hope this was a helpful use of my time for someone out there. Currently (Aug 2021) there are no other reviews and it’s showing Sold Out on Best Buy. Smaller alternative - check out the new Partybox 110. Crank it loud and God bless. ✌️ DK

I absolutely love my Partybox 310! It used for an indoor gym setting is absolutely perfect. Great sound quality, easy to connect, and plenty of volume. It is easy to move around with the wheels and isn’t insanely heavy.

Absolutely Fantastic sounds , It sounds really good, bass thumps really hard. i use this for car shows and general purpose. The speaker stand mount on the bottom is nice for when its outside so it can reach further. Battery life is amazing, will play for hours. sure its a little heavy but the wheels and the retractable handle make it a breeze to pull with you.

Even for its size, which is somewhat substantial, the sound is much better than expected. I wouldn't expect dual 6" subwoofers to outclass a single 12" sub, but they do. The tweeters are also very good. You'll need to set the EQ on your device itself and forget about the app, except with regard to the bass boost and lighting effects. It will sound great out of the box, but it's even better when you have some EQ presets for various types of media. I don't see anyone needing more than one of these unless they have a mansion, or they plan to fill a loud sports field with music. The sound doesn't seem to distort much at volumes I find myself using, but my house is small. I've never had to max it out. This speaker is, without a doubt, best in class with regard to its size. It beats out many speakers larger than itself, and anything smaller has no chance. Sound: Best in class! Portability: Yes, this speaker is portable-ish. With a very smooth set of wheels and a sturdy extending handle, it moves easily. Battery life: Having had this speaker for a couple of months, it has been sitting idle with occasional use, not plugged in the whole time. Right now, it sits at 95% battery. The sound quality doesn't seem to drop when unplugged, though I've not yet tested it at low battery.

Just picked up this speaker and WOW this thing is a whole party by itself. The sound is crazy loud, the bass hits hard, and the lights make the whole vibe feel like a real event. Perfect for cookouts, house parties, or even just chilling in the backyard. Loud, clear sound Bass that shakes the room Light effects that match the music Long battery life Easy to roll around anywhere If you want a speaker that brings real energy, the PartyBox 310 does NOT disappoint. Highly recommend it.

Seriously amazing sound, lots of bass. Love the portability of it as well. It's a little heavy to lift but managble. The lights, options to change the light show and app for equalizing make it uniquely yours. Bring the club with you with this speaker!

This speaker completely exceeded my expectations. The sound is extremely powerful, with deep bass and crystal-clear highs even at full volume. I use it for parties, gatherings and even just around the house, and it fills the room easily without any distortion. The battery life is great and the LED lights make the whole experience even better. If you want something loud, clean and reliable, this speaker is totally worth the price. One of the best purchases I’ve made at Best Buy!

As a frequent party host, the JBL PartyBox 310 has been a fantastic addition to my gatherings. The sound is powerful with deep bass, and the light show creates a vibrant atmosphere. It's easy to move with built-in wheels and handle, and the 18-hour battery life keeps the music going all night. The speaker is durable and splash-proof, perfect for outdoor use. Connecting via Bluetooth, USB, or AUX is straightforward. Overall, it’s an incredible speaker that brings energy and fun to any event. Highly recommended!

Bought aa open box item stated as excellent condition like new but came damaged with dents!

I have been waiting for them to return to stock I was going to buy Soundbok if this did not become available, I am so glad I waited. The sound is amazing (make sure your MP3s are of good quality). I also did the FIRMWARE update that made it louder, my neighbors do not like me anymore. It's heavy but manageable, like others say I wish the wheels were wider making it steadier during transport. I can't wait until the 2nd one comes in... The BASS is something on it. I have some songs that are heavy on the low end and without the bass boost on it's deep when I turn on the setting to add extra base it vibrates everything in the room. I have used it for about 3 weeks now and it's on its first recharge. I think with 2 of them my theater sound system will be complete. That is my justification for the 2nd one......DONT JUDGE...LOL

I use it for flag football, and it’s absolutely phenomenal. It is a bit of a heavy speaker, but the wheels make it manageable. There’s some songs that just shake the Earth with this speaker, and indoors, you might not even need the max volume. It’s also louder when plugged into an outlet which makes it a bit more bananas. Overall a very fun speaker and I love the investment in getting it. Don’t buy at $549, I bought it on sale for $300. Just wait for the right time.

Great quality sound....with easy connectivity. This is a perfect choice for anyone who wants to avoid the hassle of connecting tons of wires before setting up some great quality sound. It's not like a generic karaoke machine. It's sound quality is of a much higher quality, it's loud enough to cover a 50-60 people venue. It comes with even a guitar input. Its portability and powered with a battery add the icing on the cake. Loved it !!!

After doing quite a bit of research online, I bit the bullet and ordered the 310. I was quite impressed with the sound and deep bass signature. I wondered how a second would sound in stereo, so I ordered a second one. Wow! I would definitely recommend this Partybox to use an indoor concert, and it sounds great outdoors! Used it for an evening bonfire with the neighbors, and I'm impressed with the battery life. We listened to music for 5 hrs with the bass boost on, and it didn't give up at 75% volume. Love it!

The JBL PartyBox 310 delivers powerful sound, deep bass, and vibrant light effects, making it perfect for parties. With long battery life, Bluetooth connectivity, and easy portability, it’s a fun and reliable speaker for both indoor and outdoor use.

We have used this speaker many times for over a month now. We also purchased the microphones separate which connect to it. The sound quality and durability are fantastic. I left it in the bed of my truck over a weekend at the beach (I’m sure it was well over 100 degrees) and it did not affect the speaker at all. The speaker is extremely loud and the sound quality does not go down as the sound goes up as many others do. The battery seems to last forever. If you’re wanting a party speaker, this is the one!

The JBL PartyBox 310 is more than just a speaker; it’s a musical powerhouse that’ll elevate any gathering. Here’s why I’m singing its praises: Sound Quality: The PartyBox 310 delivers a slightly boomy sound profile, perfect for various music genres. And guess what? You can even crank up the bass using the Bass Boost feature. Customizable Lights: Those circular RGB lights? They’re not just for show. They sync with the beat, creating an electrifying visual experience. Your party will be lit—literally! Musicians’ Delight: With mic and guitar inputs, this speaker caters to musicians too. Adjust bass, treble, and echo controls for the mic, and let your inner rockstar shine. Loud and Proud: The PartyBox 310 can get seriously loud. Whether you’re hosting an outdoor bash or an indoor dance-off, it won’t disappoint. Companion App: Fine-tune your sound using the graphic EQ in the app. Customize it to match your musical preferences. Built for Gigging: Yes, it’s a bit large and bulky, but that’s because it’s designed for serious performances. Take it to your next gig, and watch the crowd groove! In summary, the JBL PartyBox 310 is a worthy upgrade from its predecessor. It’s loud, versatile, and ready to party. Whether you’re a DJ, a karaoke enthusiast, or just someone who loves good music, the PartyBox 310 won’t disappoint. Get ready to turn up the volume and create unforgettable memories!

The JBL Party Box exceeded my expectations! Its powerful sound and vibrant LED light show created an unforgettable party atmosphere. The portability is a game-changer, and the long-lasting battery ensures the music keeps going all night. The easy connectivity options make it a versatile choice for any event. JBL has truly delivered a speaker that combines impressive audio quality with an immersive party experience. Highly recommended!

The 310 overall has enormous power. Another big plus is the battery life. As far as bass is concerned, you're getting plenty of that considering the price range. It has customizable RGB lighting and a wheeled water-resistant design. The circular lighting look ring shaped and more sound responsive. This speaker performs best when it's off the floor or deck. Would I purchase this again? ... Yes! This speaker performs very well for my need for the birthday party of my daughter arranged in temple hall.

Great sound quality, blows away Sony and other competitors. Bass is outstanding for having no subwoofer. Highs are a little more subdued than I’d like, but many people would prefer it this way. Bluetooth range and quality are perfect. Easilly streams lossless audio, doesn’t skip often Light show is pretty fun but I’m also very happy it can be disabled. Battery life is astounding, easily hits advertised times at half volume. Also very easy to keep it charged with car plugs and portable batteries. Build quality is excellent. Great attention to detail, solid, handles are very sturdy, wheels roll smooth, telescopic handle is awesome. Absolutely love that it has a pole mount on the bottom. Issues I have: Absolutely needs an EQ option in the app. The three modes for bass are not near enough customization. The EQ buttons on the speaker only control microphone and don’t do anything for music input. Microphone control is mediocre. Needs to have a way to adjust microphone volume without turning the physical knob. Should also have a balance fader for input and output. App is glitchy. Sometimes loses the speaker or cuts out sound for a second when making an adjustment, even changing volume. Volume is much too low for using as a DJ speaker for more than 50 or so people. Just barely loud enough to do a small wedding ceremony. Isn’t any louder than many much smaller Bluetooth speakers. Would be nice to have XLR in and out.. but I guess space saving is necessary. I wish it at least had a TRS port for aux.

The party box is absolutely amazing! We have used it every weekend since purchasing. The sound quality is SO much better than our last machine. The wheels and suitcase-like handle make it easy to transport. And it’s CORDLESS?! Convenient slot on top to put an IPad for those that may need help with lyrics. Lights dance along with the song being played. Honestly I can’t think of any way of improving it.
