Customer Ratings & Reviews

Bought 2 of this JBL ultimate party speakers and JBL 320 I Owen 3 of this they sound awesome loud the bass hard shake the house.

Big upgrade to the 1000s. They are just tiny bit louder and hit little deeper than the 1000 but not by much. But if you are into the light show these are solid. Also the bluetooth connection whit your phone and on party mode connection with other speakers is drastically better than the 1000s. You can walk anywhere around your place with the phone and the connection wont stop unlike the 1000s. Highly recommend. I dont know about 1700 a speaker but for 999 which i got it for its absolutely worth it.

Beautiful sound and clear beautiful light show easy to move around. It is the ultimate sound for a party of any kind home the yard or a small venture amazing

The JBL PartyBox Ultimate is a powerful, high-end portable party speaker known for its impressive sound quality, especially its deep bass and clear highs, and its vibrant light show. It's designed for large spaces and events, offering loud, immersive sound with features like Wi-Fi connectivity, mic and guitar inputs, and the ability to link multiple PartyBox speakers together. While it's a powerhouse, its size and weight make it less practical for smaller spaces and everyday use.

Unbelievable sound, bass is amazing and the lights create a club like atmosphere

Do not buy this! Bestbuy will not package this well and it will get destroyed in shipping!!! They only used this light foam and it was destroyed on arrival.

This speaker is all you need to party. Loud, clear, tons of bass and has Chromecast which was a must have for me. 10/10 on this one.

Great sound kind of heavy good base.  but you have to subscribe to their music platform.

I highly recommend this partybox if you have the extra cash to spend. Super loud, bass is amazing, and the lighting is out of this world for a party box. Cons: Its on the heavier side so going to need a friend to help carry. Its called a portable party box but its not really portable. Going to have to plug it up to use it unlike the party box 310 and 320. Other than that the speaker is amazing. Used it at my brother's wedding and a lot of family and friends really enjoyed it.
