Customer Ratings & Reviews

This was given as a gift and did not disappoint. It is the largest party box available that is portable (larger ones need to be plugged in to an outlet to work) sound is clear and crisp and the bass is deep. Lights are cool too. Easy to use.

Love these, is my second one. Extremely powerfull for a battery powered speaker. The battery life is unbeatable, sounds amazing, very good bass. Has multiple eq setting adjustable bass, lights, preset sounds. Also comes with an app to controll everything

Wow! This speaker is awesome. I am hapoy i returned and ION speaker amd decided to buy the 310. This speaker is ver loud and clear and has just the right amount of bass. You wont be disappointed if you decide to buy this speaker.

Love JBL and have many smaller speakers as well. Wish you could sync them all together, but honestly the only knock. Sound quality is amazing and very easy to transport. Wanted to get the Powerbox 1000, but the fact that it had no battery drove me to the 310 and I am not disappointed. Battery life is amazing and is plenty loud enough.

By far the best portable Bluetooth speaker on the market. Blows away the Bose S1 and Sony speakers that are comparable. Would highly recommend this speaker if you want sound a full rich sound. Even when I plugged this PartyBox still gives you punchy bass with a long battery life.

Awesome speaker!! Way louder then I expected and battery life is good for a speaker that size and loud.

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

Awesome sound and versatility. It moves like a champ from my car to any venue or city. From iPod to iPhone, from Cumbia to Samba, Tango to Waltz. The classroom shines as well as the open spaces like the gym or stable! It makes my heart beat with every song, because it carries true sound that makes my people, young or older, move and smile. Simplicity of buttons changing and portability with or without electricity connection

THIS SPEAKER IS DEFINITELY MORE THAN I EXPECTED. THE SOUND QUALITY IS PERFECT FOR BOTH INDOOR AND OUTDOOR USE. I HAVE ALWAYS BEEN A BOSE OR SONY SUPPORTER, BUT I HAVE BEEN TRANSFORMED TO A JBL SUPPORTER.

Great sound- long battery plus a 120 volt cord. Lights are cool

Excellent speaker. Loud. Great bass. I love that it's a little bit waterproof.

I love the quality sound, the lights and the fact that it has batteries and you can take it anywhere. Also the funny sounds and special effects. We use it for Karrie and love it. We use 3 micrófones. We love it!

This bad boy bumps compared to my 110! I was expecting a slight difference in bass/sound, but DAAAAAMN BOII I HAVE MY COWORKERS AND NEIGHBORS COMPLAINING WITH THESE! If you're looking for speakers that don't need to be plugged up with crisp sound and bass....this is it. Definitely curious on buying the bigger versions now that need to be plugged for even bigger parties ha

Great party speaker however I felt the partybox 110 had more bass even if the speakers are bigger on this one. Like the portability of the wheels which you don't get on the 110. The battery and range on this is great. Can be 2 rooms down and would still play music

Sounds great, gets really loud when cranked also the bass boost thumps. Retractable handle and wheels are a nice feature.

This speaker puts out great bass and great sound even when on battery. Definitely recommend for family outings! Battery lasts all day and the wheels make it easy to bring with you.

I give it a 5 star rating because it has excellent sound quality I have been very happy with the product and it’s compact enough to carry around and play all night without having to worry about charging it. Can play all night without the battery getting low.

I'm coming up on 2 years of owning this product. The sound quality, bass, battery life are all great. I've only had it die on me during a party once, but that's not a big issue. The speaker becomes stronger while plugged in, so I'd recommend leaving it plugged for house parties. I also use it with my computer to watch movies, and it's great.

The best, tiny and most convenient rechargeable, Bluetooth sound system

amazing party speaker, its loud, has great bass love all the features and the jbl app. This is great to just have for parties, sitting by the fire, playing music washing your car or at the beach. This is worth every penny. JBL by Harmon Karmon great company
