Customer Ratings & Reviews

Yes it is pricey, but the sound is so well balance it sounds awesome. I have used it for family gatherings. And everyone loves the amazing sound and light show it displays. It is a little on the heavy side so I stongly recommend to go with the 310 which has the wheels and handle. Very loud and awesome speaker.

Amazing sound!! Love the easy transportation!! Has the easy connection to any phone.

I love this thing. Got it open box excellent condition for $343, and it’s the best value audio equipment I’ve ever purchased. Sound is full and loud with surprising bass for a speaker with only 2 6 1/2” woofers. Everyone who has heard it has been amazed. Can be rolled wherever you want and seems to have great battery life. Sound takes a marginal hit when on battery, but is still exceptional for a truly wireless device. Bluetooth connection is strong. About the only thing that would make this any better would be airplay 2. That would really round out this speaker and make it an absolute must-have. If you are on the fence, I say go for it.

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.

Speaker is perfect, I bring it the basketball courts Monday-Friday Battery life is long and speaker does get loud with the right amount of bass My team and I love it

Sounds Great easy to move around. It has wheels and a handle. Very convenient!! And it’s loud! Best speaker I’ve ever bought. I love it.

I totally love the sound very high quality, the light show and most importantly you can carry it wherever you want. Before I got this one I bought a different brand, but I ended up returning it. A little pricey but I still think it was what I wanted. Wort the wait to get it !

10/10 highly recommend! Lightweight unit that comes with extendable handle and wheels for effortless transport. Beautiful bass and awesome lighting that’s accompanied with a long lasting battery.

It was pricey bur love this speaker. Can handle small outdoor parties like a champ. Good bass, goos battery,

Super bass! Exceptional sound, various levels, lighting, portable, wireless charging- amazing for the beach or party’s - need I say more?

This portable speaker is lightweight and loud! It made our party rock and we would buy again!

really good deep bass but weight is so heavy really cool feature that we can add multiple phones once i’m using that in my semi truck it’s a really nice base so I don’t have paste thousand bucks on sub go for anything

Great sound and base. Love my new speaker. I can take it everywhere I go. The wheels make it easy to move around. Great purchase.

Amazing!! JBL you out did yourself!! Great sound, loud and easy to transport! The JBL microphones sync up perfectly and add so much fun to a party!!

Speaker is Really loud and the quality is amazing. Pretty good battery life too. Wouldn’t use inside your house as the walls will literally shake.

Great speaker! I'd give it 4.5 stars if I could. It has excellent bass and the overall depth of sound is really good. The app is fairly easy to use, and the settings, while relatively simple do provide some extra control over levels. I've read reviews that said the sound clarity was not the best, but compared with other similar speakers, I found these to be superior in quality. The better sounding speakers tend to be much smaller, or much more expensive. The lighting effects are just ok, but aren't a big priority for me. The one thing I'd say is a slight drawback is that when the speaker cabinet is upright, there is really no stereo effect, but that's to be expected with vertically aligned speakers, and why I'll be buying a second one soon!

Best overall speaker that jbl makes. It’s portable and it charges. We have the jbl 1000 and this one sounds almost as good for quarter of the money and you don’t have to have it plugged in

Speaker is nice and loud. Had the partybox 100, but returned it after buying the 310. Better battery life and louder. Will have it outside alot and the basic waterproofing will not have me worrying about getting it wet. The handle and wheels are great for moving the speaker around

The Party Box 310 has exceptional sound & bass. I was expecting a decent sound out of this speaker. What I got out of this speaker was far more. Not only did the sound exceed my expectations, I took it with me floating down the river. Fit perfect in a raft of it's own. The speaker wasn't maxed out, but the whole river was jammin'. No distortion, cracking or rattles. It worked awesome, I couldn't have asked for more. The battery was fully charged & lasted at least 12 hours before I plugged it back in.. The battery still had a good charge in it, but I needed a full charge. I'm saving to get a twin, Gonna call them my Twisted Sisters

This is a fantastic speaker, with the ability to pair with others, an easy to use app, and interactive lights, it's an immediate hit at every function.
