    Easy to set up and connect. Initial charging didn't take that long and we used it for several hours without needing to charge. The sound quality is excellent and the light show feature is very cool. I paired with the newer JBL bluetooth cordless mics and the quality is excellent. I definitely recommend!

    Absolutely love this speaker. If you’re heavily debating on it but scared by the cost, just go for it I promise you won’t regret it. Has been the perfect speaker for my family whether it’s indoors, outdoors, BBQ’s, lake days, camping, and of course karaoke nights, etc. this thing is POWERFUL and has great sound quality. I originally bought the 120 and loved it so much I upgraded to the 320 and gave the 120 to my parents. (Both pictures 120 on the left 320 on the right) absolutely love having the wheels it makes it super portable. JBL is the best

    When I tell you i made the best decision yet. I wanted a good speaker for my july 4th bbq and this speaker did not disappoint. Its exactly as pictured. The sound has great clarity. It comes with a handle so you can roll it like luggage lol instead of heavy lifting. The sound made seam like i had a dj in my backyard thats how good it sounds. It also comes with a app easy to work the speaker without getting up to do so which is a plus for me. The highlight was when it got dark my husband was like a little kid enjoying the different light features and the different beat sounds you can add like your a real dj. So go run and buy it.

    Great speaker, purchased Jbl Party box speaker 320 during black friday. Long battery life, light show is a nice touch. Bluetooth connectivity is fast. I found that for best bass sound place near corner or close to a wall. The only con found, you will want more sound or you'll want to upgrade to the next step up.

    I couldn’t be happier with the JBL 320 speakers. The sound quality is incredible—crisp highs, punchy bass, and clear mids. Whether I’m listening to music, watching movies, or gaming, these speakers consistently deliver immersive audio that fills the room. The build quality is also top-notch. The sleek design fits perfectly in my living room, and the setup was a breeze. They’re versatile and pair seamlessly with all my devices. JBL has once again proven why they’re a leader in audio technology. Highly recommend these speakers for anyone who values premium sound and style. Worth every penny! Swappable battery is a plus!

    This speaker sounds great. Larger than I expected and heavy but it has a retractable handle like a rolling suitcase that makes it easy to move.

    This was a Christmas gift for my husband. He has been wanting the speaker for over a year now and I finally gave in and purchased it and so glad I did because it is such a great speaker. It is so easy to navigate through the app and the lights make such a great light show for any party or just showing it off to friends. This thing is better than what we expected it to be and so glad we purchased such a valuable item through JBL. We have about three smaller speakers from JBL and never had any issues from them so we will continue purchasing JBL products.

    I bought a sony and returned it for this. I could've been more happier. This thing is very loud for its size. The bass is insane. I love the swappable battery and the light shows

    I recently bought this JBL speaker and purchased the microphone set to go with it same brand. It was expensive but it was the best quality investment I could’ve made. Everyone at the party had fun as soon as we plugged it to karaoke in my iPad. One speaker sounds pretty loud and the bass is on point. The microphones are a must for sure great quality and easy to connect.

    Purchased brand new but received the JBL speaker as if it were an open box. Plastic came cracked and missing battery. Since I had everything out of the box already, decided to plug it in and try it out. Sounds amazing. Bass is incredible, speaker is very loud and the app makes it fun. Definitely exchanging for a new speaker. I cannot comment on battery life since I did not receive the battery in the box.

    Very pleased with my purchase, now I can crank up some music on the go and have a considerable battery life to enjoy. Should I have bought one sooner…? Yes, glad I got the new and improved version. Good Bass, crisp sound, loud music it marks all of the boxing for me. JBL keep on Jamming!

    Professional deep base sound, the light show livins up the room, a little more powerful than the JBL 310. AWSOME overall sound. Only thing missing is a remote.

    We have the JBL 710 as well. But, needed something more portable for on the go with BIG sound that we’re used to with the 710. The 320 did not disappoint,
