Customer Ratings & Reviews

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.

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

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.

The Bass is AMAZING, best purchase I’ve ever made. The bass can be punchy and deep and there’s an app to adjust its bass even more with an EQ. The battery life is around 5 hours or so for me and the sound is just too good

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.

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.

I love this speaker, its a good buy. Base is great, tremble is great plus i can move it around like a suitcase, very portable and easy to understand.

This is hands down the largest and best portable Bluetooth speaker on the market. Anything larger needs constant power. I compared it to similar models with LG & Sony. I’m a Sony person, but at the end of the day, this was a better product. I use it for walk up music at my boys baseball games and have used it at an outdoor festival. It turns heads. The bass bumps but you can turn that feature down. It says it will run 18 hours, but that is at a lower volume. I think it ran 6-7 hours at 100% for me with the bass at max level and the lights on. I just plugged into power after that. No distortion at max volume. It plays lower when plugged in than on battery. Still in my opinion the best blue tooth speaker. I paired it with the JBL Encore, but I think I will go back and get another 310 cause I’m so happy with it.

Great sound, love the lights on it. Every person that has seen it has asked about buying one lol love it battery life is great!

Great quality and sounds perfect and so load and specially if you use the boost bass i really love this party box from jbl

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

Excelent sound. Powerful bass. Long battery life. Easy to move around.

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

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 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!

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

This is one of the best soeakers for its price range. The amound of bass this has is unbelievable. The speakers sound so clear as well. I would definitely recommend this to anyone who likes loud music and with the wheels and handle its easy to wheel around.

Sounds great and with the JBL mics karaoke nights are fun. I really like that we can take it anywhere we need to.

This isn't a over rated, more wattage than advertised, you might step in from time to time if you don't protect yourself from impulse buys. This howls at the moon like the alpha wolf it knows it is! (Do you want to howler at the moon like the alpha you think you are?! Good news! You can it has a microphone input so everyone in your neighborhood can hear your yodeling!) This has a gain control so after the speakers break in period is done and you wanna hop like a real tree frog, then go ahead and r√ that gain control up til you feel like a real b0y! 240 watt max power is more power than all the CAR stock stereos from the 1990's combined! And if you wanna get your rave on it has party lights and dj settings and for 19.99$ more you can get a upgrade for it that makes it turn into rZ~dZ So go ahead and buy it if you like great sound quality even when it's cranked up loud enough to upset your neighbors 2 blocks away. (It's more fun than you think)

very good purchase! sound quality is surprisingly awesome and is great for my backyard and wheels make it easy to move around!!
