Customer Ratings & Reviews

I recently bought this speaker and I think it is great, it has a phenomenal and unreadable sound, the easy transport of it makes it easy to carry anywhere without discomfort.

Jbl for the win... one of the best sounding Bluetooth speaker I have owned, from clean audio to long lasting battery life. Highly recommend!

Seriously impressed. I would suggest downloading the JBL app to adjust the eq and other settings and to update the software. So loud and clear. Bass is definitely strong but not overpowering as long as you adjust it. So glad I made this purchase instead of the smaller portable one. Maybe a bit large but so worth it!!

Awesome sound , pumps perfect for outdoor parties and get together . Perfect size and portable, battery life is awesome, charged it one day about 80% and after two consecutive days of use minimum for 4 hour playtime, still at 70%

This speaker is an absolute game changer. The sound quality is powerful, clear, and the bass hits hard without sounding muddy. It easily fills up any space, whether it’s indoors or outside, and still sounds great even when you turn it up loud. The light show is one of my favorite features—it syncs perfectly with the music and really adds to the vibe. It makes every get-together feel like a real party. The battery life is also solid, lasting up to around 18 hours, so you don’t have to worry about charging it constantly. I also like how easy it is to move around thanks to the wheels and handle. It’s definitely not small, but it’s very portable for how powerful it is. The mic and guitar inputs are a nice bonus too if you want to switch things up with karaoke.

the jbl partybox 310 is a good speaker, I Love this speaker it does an amazing job of bass and sound quality, it has a built in battery so you can take it to the lake and enjoy time with the wants you love.

Amazing portable speaker! Has a lot of cool features like the changing lights and soundboard buttons. My favorite aspect is the heavy and hard hitting bass. So far 3 friends of mine have bought the same speaker after seeing amd listening to mine! I highly recommend it to anyone who loves quality sound.

Neighbors kept playing their music loud next door so i stepped up my game and bought this JBL PartyBox 310 and played Iron Maiden full blast! Oh it sounded great! House was bumping to the beat and the next day was waiting on their turn but nothing. I’m planning on getting another to sync them together lol

Amazing speaker tons of bass power max volume probably 5 hours but that's more than enough for most things running in my FedEx truck all day everyday

This is a lot of speaker. I love the speaker but be prepared to get the cops called on you or complaints from your neighbors if you're running it with bass boost on and at full volume. You may want to consider getting an amplified sound permit if you want to be able to use it to its full ability. It also has a really great sound at 50% so it can be useful in other settings as well. I really like using the air horn button although not everyone is a fan LOL. I purchased this to use at our campground where we have our camper and I was actually asked to take it home and not bring it back because there was too many complaints. The type of music that you're playing also makes a difference, if you're playing some electronic music with a lot of bass andn the bass boost turned on the bass really carries and will rattle the windows of houses or campers that are not even that close by. I ended up also buying a JBL Boombox 2 so I could have something to use at the camper. The problem that I had with the party box 310 was that I was pretty good about not turning it up too loud but as the night went on and I drank more tequila I had a harder and harder time not turning it up and I would eventually get sound complaints. So basically if you have discipline and a wide open area with no neighbors nearby this is a great speaker but just be prepared to get complaints if you have neighbors. If you are trying to use this in an apartment complex or in the summer with the windows open and nearby neighbors you might want to look for something smaller. My friend bought one of these too and we've used them for a couple of outdoor events with DJs and they've provided more than enough sound for our needs.

Very impressed . This JBL 310 is just perfect . Bass - sound quality - battery life ✔️✔️✔️ 100% satisfied . Def recommended.

LOVE THIS SPEAKER 5 star all they everyday!!

Amazing sound, great quality, good battery life. Portable for it's size, easy to carry and handle, easy to play with.

Perfect for poolside get togethers or for back yard bbq’s.Good sound easy to move around and loving the light show.

This speaker is very loud, clear, and portable. I have ZERO complaints about this speaker. This is like all of the kther JBL products I have purchased. 5 star purchase for sure!

Right out the box this thing bangs hard, It is very sturdy, I absolutely love it, I have to save and get another one so I can dual the two. I ended up paying full price, but try to wait until it goes on sale again.

Dont waste your time looking at Sony or Soundboks. I am an audiophile and dont mind spending $$$ on high quality sound and this blew me away. The fact that is is portable and putputs this level of sound (and bass, deep bass) make this a must buy for people looking at this level of speaker.

I bought 2 one for my dad and one for myself, overall it is amazing. Perfect for parties, or small reunions. “Loud” is an understatement. Very easy to connect to mobile devices via bluetooth. My dad loves his speaker as well. I take it everywhere. The handle makes it easy to haul around. My son loves it too.

Love it. Great bass and great sound! The app is super nice as well and is a must download for this speaker. I didn’t enjoy how it had strobes and colorful LED lights since I like to use it in my room at night, but the app allowed me to turn off the strobe feature and customize in different ways according to my likes. Definitely best speaker investment for me so far

The JBL Partybox 310 was released in October of 2020 and I heavily underestimated this speaker due to age so I bought it last year and it even have some wins over the JBL Partybox 320, mainly the more neutral sound signature and the rubber feet on the sides that come in hsndy as a trunk speaker and it can handle the extra power of being plugged in. The 320 distorts pretty quickly with a bass heavy eq in AC mode. Treble, mids abd bass compliments each other pretty well but treble extension. Midrange separation and low bass extention is good but it doesn't sound as impressive as the 320. If you can get the Partybox 310 on sale its a much better valued speaker then the 120 for a extra 30 to 40 bucks although the light show and futures did age a good amount
