Customer Ratings & Reviews

Though a bit on the heavy side, this speaker has wheels and a retractable handle that make it easy maneuver around. It’s ruggedly built feeling like a pro audio JBL speaker rather than a consumer level product. The sound is fantastic with its adjustable equalizer and broad settings. It has crisp and resolute highs that aren’t piercing but pleasant. The low are rock solid giving the impression that the unit has a subwoofer hidden somewhere inside. The lights might be preferred by some but I tend to turn them off. I wish that there was an option to permanently disable them at power-up so here’s to wishing. Using the JBL app, I link two of these together for parties and get togethers. I have yet to run out of power telling me that the charge lasts well beyond 4 hours running at reasonable high and continuous volumes. I have no idea what the max runtime is but know that it has to be really long. The app makes it a rockstar standout!! I hope that JBL continues to build out the app functionality as it’s good but there’s still more that could be done. Having tried other portable speakers, this one stands apart for its rugged design, sound quality, and ease of use. I would strongly encourage others to compare this to any other speakers and let your ears decide. Personally, I would easily recommend this to family, friends and any others in the market for a DJ level, battery powered portable speaker that simply rocks!!

This is the most amazing and powerful speaker I have ever bought. Generally I have been a fan of the company from Boston but this is the first time i stepped out of my comfort zone. I will say I was lucky enough to get one of these. They have been in short supply and I kept checking on the BB website everyday until I hit the jackpot. The speaker plays right out of the box, no complicated connections. You can actually connect multiple devices thru bluetooth and keep cutting out one to maintain a rhythmic flow to dance music just lie the DJs do. The speaker itself is very powerful with a nice deep base and when you push the Mega Bass button, the sound blows you away. This is the one Party speaker to have. Very conveniently rolls on wheels so it is not cumbersome to carry around. We recently used it on a party boat for karaoke and dancing and what a great time we had. The rechargeable battery lasts forever with a high level of loudness and colored lights on through out the duration. Kudos JBL!

Amazing speaker. Sound is excellent. Will go as loud as you need it. Lights add to the party. Easily portable with suitcase like wheels and handle. Probably one of the beat bluetooth speakers ive owned.

I love the sound , loud and bass is great . Also lights on it are pretty cool .

This speaker is great! Caught it on sale for $100 off but after using it, I’d have no issues paying full price! When my friends hear this speaker they’re shocked how good it sounds. The bass is great and the treble and clarity are great too! You won’t regret getting this speaker! The kids enjoy using the microphone port which we bought 2 mics from Amazon. The battery life is great when not using the lights and it’s also louder when using the speaker while plugged into an outlet.

Sounds amazing crazy bass battery life is long and doesn’t seem to affect sound using battery over ac. Handle and wheels are nice touch for transportation. Had a Samsung Xt 70 or something like that with the 10 inch sub this has more bass than that one and and it has the benefit of transport definitely recommend

It's expensive, but it's that good! Pairs with my android phone easily and doesn't glitch. I was unable to pair it to my tcl tv. It's one of the first speakers that I have that can play without distortion at full volume. The bass is amazing. I'd love to purchase a second one. It's too loud to play outside at higher volume to keep from complaints being made which It's entirely capable of. One of the best purchases I've ever made. The light shows amazing and the battery lasts plenty long for me, if not it can be plugged in in a pinch. I did try a usb with music but i don't think there's a way to access what file will play next - it does work though. I also love the guitar strum it plays at shutdown and startup. Absolutely unbelievable!

Great battery life , easy to set up , the wheels to allow portability . Solid sound and smooth base , the lights are colorful too. I use it at my night job and it takes me through the night real quick . I love it .

Love it. I was a little worried about ordering something this expensive, based solely on reviews. Figured if I didn't like it I could return it. That ain't gonna happen! The sound is really good. The bass is really really good! Although the partybox app does not include an equalizer, there are plenty of third party apps you can use to boost the mids and highs. The unit paired easily with my phone and is very versatile with the ability to add microphones and/or a guitar thru 1/4 inputs. (This can be good or bad depending on who's singing)! I also can sync it with other speakers in my house by using the 3.5mm input from an echo device via the alexa app. The build quality seems to be very good and the design of the unit was well thought out. I could go on and on, but I would much rather listen to it than write about it:) I would recommend this speaker to anyone.

Everyone who has been around this speaker cannot stop talking about the sound, the lights and the ease of use of it. The sound is amazing. It is loud and clear. We have used this for parties and connected to our outdoor projector for movie night. We could hear the movie clearly. It connects quickly and easy to phones, laptops, etc. You have the ability to adjust the sound and lights as you like. I am very pleased with this product.

I really love this speaker great sound awesome bass very loud and I really like that. It has wheels and the handle that pops out of it. Makes it really convenient to move around with ease.

I love it. This speaker is incredible. It has a nice sound and battery life is also good. The light show is a bonus.

Absolutely love this speaker. It is super load and the bass is great. Love that you can link multiple together and you don’t have to have it plugged in at all times.

Looking for a backyard party or any party? Open space or closed. Big hall or small. Oh this boy is crazy! I love it. Friends loved it. Lights, super bass, quality of music, sleek design, portability makes it even more useful. Since its little heavy if you try to use tires, sometimes it wobbles on left and right, so have to be careful while driving but I guess that’s the least thing to be concerned. Single advice, at this price, it is purely and straightforward choice - ONLY Choice. You won’t regret it. Oh and that 3 different auto DJ Party music. We can’t get enough of it.

Amazing speaker! It took me 10 months to finally get this as it was constantly out-of-stock at all online retailers. The speaker connects easily via bluetooth to my Android phone and yes, this speaker is loud - if you want it to be! It's strong points are definitely in the mid-range to low sounds; i.e., songs with bass are excellent. It does lack a little bit on high notes (treble) but nothing to steer you away from purchasing this product. This is a great backyard/pool speaker and I recently just brought it to a birthday party - everyone made a comment on how awesome it was. So, if you can actually find one to buy, I recommend it!

The bass is amazing ive dropped it like 3 times and it still works great its not in the best shape but works fine the only thing i have a problem with is it wobbles sometimes when you pull it but other wise its great

Previously had the JBL PartyBox 300's and had major issues with them like TWS (True Wireless Stereo paring) Harmon / JBL parent Company couldn't sort out! Glad I returned them after replacing them twice. Working with Best Buy I got them replaced with the the 310's instead. The JBL PartyBox 310's are so superior to the 300"s It fixes all / most of the connectivity issues and a few more gadgets / like wheels (portability) and water resistance features and more that only come on the 310's. It's like the 300's were a beta test for what needed to be addressed and the 310's are the new standard. People may say it's not worth the extra money (list price is the same for both models) for the newer 310's but when using two or more of them together the 310's work as advertised and the 300's do NOT deliver. A great man once said, "Buy the best cry only once" I think the PartyBox 310's will deliver entertainment and enjoyment for the years to come!

Sounds Amazing Light Show is great Deep Bass Love using the horn sound effect At 80% volume the battery lasts 3 hours with lights

Love this portable beastie! This has great sound and thumps. Has good highs and lows. Great for parties or karoake. Has inputs on the back for both a mic and a guitar. can adjust volumes separately. There is a jbl app that can be used also to adjust EQ, play with color patturns of the lights on the party box. This the largest of the speakers that is battery powered. The larger ones have to be plugged in. It also has wheels and an extendable hand to roll this thing as it is descently heavy. Can also be placed on a speaker stand. Can connect via bluetooth or aux plug. I love this thing.

⭐️⭐️⭐️⭐️⭐️ I am very satisfied with this JBL product. The sound is powerful and clear, with deep bass that sounds great even at high volume. The Bluetooth connection is fast and stable, and the battery lasts a long time. In addition, the design is modern and durable, perfect for use at home or for outdoor activities. It is definitely a great purchase and I highly recommend it.
