Customer Ratings & Reviews

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.

If you’re looking for bringing fun with you this is the one thing that is a must! My family loves this great addition for parties and around our pool.

For residential home use, the Partybox Ultimate is ultimately going to get your neighbors’ attention! Wow, great sounding speaker with full range of highs, mids, and lows at any volume!

I went thru 3 models..finally settled on ultimates..adjustable sound helps wuth different music.dont waste time.loud music cost money!..

The sound is amazing. To take it to another level, get the PowerAmp app.

Great sound quality, very loud, and easy to move around with the built in wheels.

This speaker is definitely the best, sounds really good and easy to use! Was on sale when I'd get it!

This this speaker bumps, I used it for an outdoor party and received a bunch of compliments and people where very curioso about it. The bass is awesome and no distortion in the sound when we played it very loud
