I had the 320 and I was thinking I want more. Now I have the 720 in the back of a hatchback. Hits incredibly hard. Both speakers link together easily so now it's a concert.
I Got this speaker as a gift brand new and right out the box the side LED strip doesn't work. I've tried every single method of trouble shooting and am disapointed that such a high end speaker has this issue. I hope I dont receive a refurbished speaker and can get mine swapped out with a non faulty model.

[This review was collected as part of a promotion.] OK, so this thing is big, feels solid as a tank, and it's heavy! Also, it SOUNDS big and heavy! This speaker will definitely bring the party. Not only is it capable of getting loud enough to cover a few city blocks with thumping bass, yet gloriously clear mids and highs, the light show is absolutely amazing! It even sounds great at lower volume levels, if you're in a smaller back yard setting. But again, if you want a big and bombastic block or pool party, the PartyBox 720 should definitely be your go to, if it's in your budget. The mic and guitar inputs work flawlessly, so if you want to use it for your karaoke setup, it will definitely fill that bill. The battery life seems really solid, I got 10+ hours at moderate volume level, and they also recharge quickly. With the option of hot swapping them, as well as being able to power directly while charging, the party can be endless. As I stated earlier, this thing is big and heavy, so it's going to take a little knocking around while you're moving it. That doesn't seem to be an issue in my use, so far, and as long as you're not stage diving off of it, or otherwise outright abusing it, it should be able to handle the occasional party foul. I really don't see how you could go wrong with the PartyBox 720, if it fits your budget, it should definitely meet your party or quick and easy PA type needs.
[This review was collected as part of a promotion.] As the title says, this thing is an absolute powerhouse that can be used for large parties or outdoor concerts. It’s pretty massive & heavy, but the setup was effortless, Bluetooth connection was strong, and the sound quality blew me away. I also love that it could be used as both a regular speaker and as an amp! The bass is bold and clean (especially with Bass Boost on), and even at max volume there’s no distortion. It’s built to last with solid materials, sturdy handles, and wheels that make it easy to move. The LED light show adds a fun touch that changes the vibe.
For me, this speaker added a lot of convenience. I no longer need to hook up multiple smaller speakers or deal with power cords everywhere. The battery easily lasts through long events and I was honestly surprised that it could be used wirelessly with replaceable batteries, if you want to extend the time playing without being connected to an outlet. If you host events, this is a perfect fit. My only tip is to expect it to be large and loud, but that’s part of what makes it so impressive.
[This review was collected as part of a promotion.] I really like this speaker I've always wanted to get one for my home bar now sound like a concert hall so easy to use love the light show battery last a long time I really didn't find anything I didn't like about it would buy again
