Customer Ratings & Reviews

Although the sound quality is really good at max volume it will diminish the sound quality a bit, but not by much. The battery life is as good as advertised. It is somewhat portable and has pretty good range. Overall it is a pretty solid party speaker.

Love this speaker I use for little gathering/kick back/parties/karaoke (have echo control), speaker last about 7-8 hours on max volume, last about 18-20 hours at 50% volume which is more than enough, it’s very loud an bass sound great when “Bass boost” is off and better when on, it have 3 different level of bass boost. I have the 300 use I sold to get this, I use to lug around the 300 due to it not having a rolling wheel, this 310 do and a collapsible handle bar. When I don’t have to guest over, I use it for my gaming on PC it sound Great, getting another one soon for its pairing to have stereo sound.

The sound is pretty good and with the app you can change the Bass, Treble and Mid. You can also play 12 different DJ sounds - though they are clearly just for fun. You can assign 3 of the sounds to the 3 buttons on the speaker. Battery life is really good. Also the TWS worked up to around 100 feet apart. Perfect for a pool party. The only negative would be the wheels for moving the speaker. Because they are close together it can tip over as you move it during a tight turn, so move slower when you make a turn.

The quality of the speaker is amazing. The lights go to the beat and very easy to pair to your phone. The battery life is long lasting even at high levels. Its not too heavy but its bigger than you think.

The speakers sounds great I like the lights that fact that it has wheels easy to travel with it the price its not bad also its wayer resistant campare to other name brands JBL did a grat technology with this speaker if you add another speaker it's wonderful and super loud to play in a apartment great for parties ,barbecues,cook out,home of course one thing it battery dont last as long as they advertise and i say not playing the lights on speaker and not to loud playing

Speaker arrived in excellent condition and works great! Impressive base coming from a battery powered speaker. At half the price of MSRP I'll be trying open box from Best Buy again. It is quite large and heavy so if you're expecting something super portable to carry around anywhere and everywhere this isn't it.

battery life is amazing, very portable and excellent sound and loud enough for a small party

My husband loves the bass of this speaker. He also loves the rolling feature makes it easy to move. He has decided to buy another as he will be making our garage into a club apparently

Chose this model to utilize in my garage and throughout the house. The lighting syncing to the music is amazing and the ability to roll the speaker like a piece of luggage is also convenient. You are able to connect the speaker to two phones at a time but sometimes we have some hiccups with it. Overall, the sound and base is amazing. Definitely recommend downloading the JBL app to control the features better.

If you like to party, karaoke, and listen to music, this is the speaker to get! It is a bit pricey but it is worth every penny. Your neighbors will hate you because it is loud and the bass is loud. Very easy to connect to via Bluetooth and to use. It is a bit bulky and big to haul around, but it helps to have the handle and wheels to drag it around. Overall, definitely recommend!

Love it! Great bass and loud volume. I put it in my 15 passenger van up front with me and it replaced the stock radio. I only use it to play music and it bumps as if I had a full system installed

This speaker is awesome. Sounds fantastic and super loud. Battery life feels like forever and it charges quickly. App is pretty sweet too.

We bought the 110 to start because the 310 sas no available. Shortly after receiving the 110 the 310 was available for purchase so we got to compare and decide if bigger was better. The extra features, larger speakers, wheels and handle all were extra benefits. We played both at full volume and mid to see which sounded better and if the 310 could drown out the 110 which it did with ease. For our needed application on a lake island we decided the 310 was it and havent looked back. We get about 10 hours or more running it at 75% volume, no lights. We havent run it dead but got down to 16% battery life left.

This review is about the purchase and service and product bought from Best Buy‘s this year I did the online ordering and they deliver to my house free of charge what more can you ask for LOL go to the good part once I plugged it in I was totally amazed with a clarity in volume it was producing unfortunately having only one speaker mange mono I ordered the other one and sync them with the TWS and now I have outrageous Bluetooth stereo system that I can take out on my patio in the house driveway in the back of my truck wherever whenever I really appreciate Best Buy‘s stock in qualityMerchandise in their stores once again to thumbs up for Best Buy’s and JBL

1) It's possible to pair On-the-Go with a 310, by using a 3.5mm cable. The 310 would act as the main source, and use it's out line to OTG's audio input at the back. Problem is, it's not stereo, it's mono. And the sound from OTG as the secondary speaker is overpowered by the 310 (so this setup is not recommended) 2) It's obvious that OTG can be paired with another OTG. What isn't obvious is that the mic will only work on one speaker. So if you're using two OTGs to function as a karaoke system then both speakers will have music, but only one will have a mic. Each of the Mics will only be projected on their respective speakers not both. For this reason, I returned the other OTG that I bought. I wanted the mic to work on both speakers--but they don't. 3) When pairing 2 OTGs together, they have to be within about 10 feet apart. Anything more than that, the speakers will start to stutter and lose TWC connection. 4) With regards to the OTG or 310 working as a guitar amp. It's not an ideal setup for guitarists doing solos. The "gain" settings, leaves much to be desired. The speaker working as a guitar amp I think would work best with an electric-acoustic, not an electric guitar. For an electric guitar, the speaker is "a better than nothing" situation. This being said, I've never really bought a party speaker before. But once I tried out the OTG, I had to buy another one (the 310). It's that good, that a person like me who NEVER buys a party speaker... JBL made me buy two (actually 3, I ended up returning the 2nd OTG). The OTG is great for smaller parties, but for larger events, Just one 310 would do some damage--it's pretty potent!

JBL 310 party box is a game changer ! JBL 310 party box Has amazing battery quality and long range sound! I loved the bass switch mode that make the floor vibration sound or make hard beats to jam on! My mom use JBL 310 party box every day since I bought it 2023 compared owned Sony soundbar that worth $1400 . In my mother statement “ I can travel JBL 310 party box Anywhere I go and continue party with friends outdoors or at home! It was amazing watching movies on my iPhone with JBL 310 party box like I was in a movie theater when I was outdoor fishing.” Thank you JBL for making this product the best quality portable speaker for everyone to owned one!

This speaker is awesome. I had a custom demo of home audio in my local bestbuy but the bass was severely lacking even on some of their highest end speakers. This one speaker outputs wall shaking bass and super clear mods and highs. Not to mention it’s portable, so we bring it to the beach or roll it from room to room. Our best purchase of 2023

Was looking for a speaker that almost seemed too loud. Think I found it and makes me want to maybe get a second for when we have people over. This JBL has such a nice full sound to it, even with the bass at its low setting. The blue tooth seems to have a decent range compared to other blue tooth speakers I own. Solid buy! Love that your able to wheel it around. We have already had some good times with this speaker and know there’s only more to follow. Thank you JBL

Honestly this is the best multimedia speaker for the price rang. The sound quality is amazing, great bass. It makes the house floors vibrate. The karaoke is the best . You can fix and re range the mic tunes to make the sing voice sound perfect! The color display was so vibrant! Not heavy at all and very portable!

Beast of a speaker. Hosted a few backyard BBQs and parties with one of these and its been solid. always get asked by someone for the info and they text me weeks later that they purchased one too. Definitely download the app if you purchase. The few settings on there really wake this thing up and allow you to turn up or down the bass and treble to your liking, and very easily. Makes a big difference. Heavy, but the wheels help a ton. I never have it at full volume, as i like to hear the person I'm speaking with, but nice to know I can bump it up if we want. Have connected microphones for karaoke nights and works very well at that too. You can adjust mic levels and music levels separately. This may be overkill if you plan to use it in a small room or apartment. I’d get the smaller 100 series of that was the case.
