Customer Ratings & Reviews

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.

I love the the sound the lights the bass and the wheels

This speaker kicks butt! It has great sound even when turned up most of the way. Being a battery powered speaker (when wanted) it’s allowed me to retire my Ion BlockRocker. I bought a pair of JBL wireless microphones and have had 2 karaoke parties with the speaker. The lights and DJ sounds are a cool throw in, but I bought this for the battery and clean balanced sound.

I bought a JBL PartyBox 310 last year and it is an amazing speaker. Great quality. Get loud and the bass is awesome. I just order another speaker so I can use two speakers at the same time for family get togethers.

I have used my JBL Box 310 Portable Party speaker, and the sound is great, It helps me a lot because it is portable, and can use it at home and out and about and it last a long time without plugging it in, would recommend for someone that loves music at the park or parties.

This speaker is very loud and has alot of bass. This speaker works very well inside and out doors you will be very happy with this speaker and cant beat the price. You can turn it all the way up and the sound sounds very clear. You will be disappointed with this speaker.

Bought this speaker for spring break and was the loudest at south beach great sound and bass holds charge well and even works as a portable charger you can download the app and adjust the settings lights and has built in Dj sounds did I also say you can connect 2 of these together simultaneously

Very good Build quality and easy to pair with another 310...I purchased one and loved the sound quality. I then purchased a second one and wow I'm impressed with the sound quality. Battery Life is superb even at near full volume. Great item for small partys and the fact you can go portable and take them to the park or beach is even better since it is water proof to some degree. Amazing sound well worth the money.

This speaker so far has been hreat! It is loud enough for almost any outing. It is clear and crisp sounding at full volume. Lastly it holds a charge well. The only Negative is the handle is a bit flimsy it seems. Wr will see how it hold up after 6 months

Awesome speaker!! Very clear and loud. Great clean bass. Little big and heavy. But the wheels make it so easy!

The JBL PartyBox 310 is an absolute powerhouse when it comes to portable party speakers. From the moment you turn it on, it delivers deep, punchy bass and impressively clear highs that easily fill both indoor and outdoor spaces. Whether you’re hosting a backyard party or just want to elevate your personal listening experience, this speaker brings serious energy. One of its standout features is the built-in light show. The customizable LED lights sync perfectly with the music, adding a fun, club-like atmosphere without feeling over-the-top. It’s a small touch that makes a big difference in setting the mood. Battery life is another major win. With up to 18 hours of playtime, it keeps the music going all day and well into the night. Plus, the splashproof design means you don’t have to stress about using it near a pool or during a casual outdoor hang. Portability is surprisingly good for its size. The built-in wheels and sturdy handle make it easy to move around, even though it packs a lot of power. Setup is simple, and the Bluetooth connection is stable and quick. Overall, the JBL PartyBox 310 strikes a great balance between sound quality, features, and durability. It’s not the smallest speaker out there, but if you want something that can truly drive a party, it’s hard to beat.

I bought this for outdoor use - patio parties, The sound quality is impressive, The sound on the speaker is amazing. At max volume. The battery life is great. Comes with a USB port that you can use to charge up your phone or other portable devices with the speaker's battery. the lights are cool

I needed an outdoor speaker for a Labor Day weekend party at my home. I wanted something with good connectivity and a long lasting battery. I also wanted a unit that was portable and really belted out my music. This JBL Partybox 310 was perfect for all of that. Would not hesitate if I got a do over. So happy with the quality and functions of this speaker.

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

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

Great sound and all around great product I wanted a Bluetooth portable speaker that I would get multiple uses out of and this one is great. I can use it in the garage and doing yard work. The light show on the front adds extra no complaints at all.

Very good speaker good bass and very good sound clarity. Has alot of function i haven't even used yet but definitely would recommend. For me it was bettering this speaker and Sony, bose is usually my go to buy trading reviews not the best for bass. The wheels definitely helps with getting this heavy thing around.

IT SOUNDS GOOD, BASS , HIGHS AND THE LONG LASTING BATTERY, EASY TO CARRY , I WISH THAT IT CAME WITH A STAND, BUT OVER ALL A GOOD SOUND SPEAKER BOX

After spending hundreds of dollars on other high end brand Bluetooth speakers and never satisfied, finally decided to give in and pickup this bad boy. This beast is an absolute unit. Definitely recommend. The bass alone can put some home stereo systems to shame. Very clear yet LOUD. The karaoke feature and the ability to plug in a guitar is just an added bonus. Buy one. You won’t regret it!

Fantastic. Highs are a little muddled on some stuff but overall it sounds amazing, portable and gets loud as advertised. I looked and listened to a lot of units for hours. I’m not a big JBL fan but this product delivers.
