Really good sounds out of this speaker and the lights are really awesome

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.

Great sound quality and deep bass packed into a small package. It is heavy, but the rollers make it convenient to move around.

Just as described powerful speaker and portable with great battery life

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!

JBL 310 party box is a game changer ! JBL 310 party box Has amazing battery quality and long range sound!

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!

Jbl has out done them self with this speaker. The bass and clarity is to be desired.

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

The speaker quality in the sound is amazing. Have it in my garage when I work out it sounds like a concert in there. The base quality is perfect.

Great usage for all genres of music and will definitely continue to have charged up for foreseeable use. If you’re looking for a portable speaker that *doesn’t just play music — it brings the party, the JBL PartyBox 310 checks almost every box. This isn’t your average Bluetooth speaker — it’s a bold, high‑energy sound system built for social gatherings, outdoor events, tailgates, and backyard hangouts.

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!
