I didn't know you couldn't link up to the boom box 2, and boom box 3, so I'm kind of disappointed

Easy to set up

I bought this for a Christmas gift for my husband. He loves it. Was very easy to set up and connect to his phone. We use it by our swimming pool and love that is splash proof. We have a large pool (20x40) and the speaker is definitely loud enough to cover the whole pool area and surrounding area as well.

Excellent sound system

I made an agreement with one of those "rent to own" companies for just one of these because I liked the sound in the store. After having it for just one week, I went and got another...... Then I find out that you can link up to 30 of these wirelessly. I thought no way. Well long story short, I have 4 of these party boxes. Sure, I am paying about $1,800 each, but small price to pay payments I guess.... Very good sound system guys.

Not happy

When I play a song it doesn't play the fist 3 second of the song. It's super annoying and embarrassing as a cheer coach and the begging of our song won't play. I tried to reconnect the Bluetooth multiple times thinking that's the issue .

JBL Party Speaker 320

Bought my speaker direct from JBL. Had the same sale price as prime. Was allowed to use and additional coupon code i had. So great price plus free shipping. Got the speaker in 2 days. Speaker is great. Connects easy to phone and has a great app to configure anything you want on the speaker. Great bass great sound and cool lights if you want that.

Great speaker with one flaw

I really loved the redesign fro. The 310 to the 320. Everything about the redesign was perfect except one piece. It does not wirelessly connect to the 310 except for in the app and then the app only controls one speaker. For example connect together through the app, the volume would only adjust the 320 and then you had to manually go to the 310 to adjust. For this reason I sent it back and bought a second 310

Nice speaker, bad service

Speaker is great and lighting effects look awesome on the speaker. JBL shipping, delivery service and customer service is bad. Took a very long time to receive my speaker even after the issue was identified by Jbl. I wouldn't buy from them unless they are the cheapest option.

Great powerful portable speaker

This speaker is great for so many uses. Incredible battery life while playing it as loud as you want. This has great bass especially when you give it a boost with the equalizer in the app. Portable enough to take to the basement when running on the treadmill, or kitchen or office. I love it. We bought the wireless mics for the kids to karaoke and those things are awesome too. I did buy a second 320 and am still loving the PartyBox 1000. JBL makes great stuff. Love these party speakers.

Superb Bass!!!

I got one today, and it's great, to be honest. It's good at punching the chest and much more when it comes to a party. I really appreciate this piece of art.. The lighting system is also good and the DJ pad looks a little bit weird, but I'm fine with that...RECOMMENDED!

Explosive Sound

I bought this item because of the hype people keep talking of. I had actually seen two 320 models playing and the sound is incredible. The JBL party box app is great for your equalizer, mic, light shows "flashing colors" and dj sounds. The bass.is explosive. It literally shook the walls of my house made of cynderblock. The only small and even minor concern is that it is slight on the heavy side, but the wheels compensate for it.

Everything You Could Ever Want!

By dcime

This is a short but comprehensive review of the JBL Stage Party Box 320. Long name, Great product! Wow this thing is heavy. But I promise that's all for good reason. And you won't have to lift it! The weight needs to be here to bolster this speaker to produce the lows that I've never heard before on any speaker, never heard the bass go this low at home, or at parties. A terrific LED light show is also included within the speaker that you control via the JBL App. The LED's behind it is mesmori...

By Russ23
