Customer Ratings & Reviews

Amazing speaker. The mids and highs are very clear and the bass shakes my car seats and whole car. The eq makes it very easy to use.

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

It is a very good loudspeaker, perfect for patio and to have fun!

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.

Was surprised at how good and powerful this speaker is. Used it for a small function of 30 people in a small meeting room recently. Connected the speaker to my Traktor Console and it worked flawlessly. Then used it at a pool party using Bluetooth and it sounded amazing. Good battery life and easy connection

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

Great buy great price good battery life best portable speaker on the market

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.

Replaced my PartyBox 300 with this upgraded version. Same great sound, but a few additional features that make it well worth the price. Lost my 300 because of water damage. This version is water resistant and the seals on exposed electronics seem solid. Still heavy and awkward to carry, but the luggage style handle and wheels on the 310 make it a breeze. Thought I might be throwing good money after bad, but I should have just went with the 310 from the start.

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.

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

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.

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.

The speaker is a good size. I love the fact that it has a handle that pulls up amd you can just roll it around to your next spot. It is pretty good on volume. Good for a small get-together. I have had experience with the JBL party box 1000. Ofcourse price is a big difference, portability, and this one has less buttons to add to your music. But overall great speaker.

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

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!

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

For the portable size, this speaker produces extremely clear music and karaoke voice notes. The battery last very long as well.

The PartyBox 310 is an amazing speaker with a lot of excellent features. The Sound quality at all levels is awesome! I was looking for an outstanding Bluetooth speaker that would work for Karaoke and not need a mixing board etc. and would have nice fidelity as an everyday speaker to listen to steaming music. I looked at tons of online reviews for just about every option in this size/watts category and the 310 had really good reviews and was usually the top choice. The app and connection were super easy and I was blown away by the sound quality at all levels. This thing just rocks and is way more then I need in a small work from home space. But something was missing...that's right it needed a partner, the next day I ordered a second in order to have stereo and now....wow! ps the Karaoke feature is really cool and I purchased the JBL wireless mics as a topper. If you're looking for a killer Bluetooth speaker that can do it all, this is it. Get one (or two) today!

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.
