    • This speaker will blow your mind!!
Color: White
If you want a speaker that takes you to the front row of a concert then this is it! I don’t believe you could get this quality sitting at a concert either. You can feel the music! Not a single regret here! We researched and dug for the absolute best speaker and we found it! It’s deep, no static, and the sound quality is just pure. A dream!!! I’m sure our neighbors a few blocks down can hear whatever song we’re playing clearly. We didn’t even turn it up all the way. Which we probably won’t ever do that. It’s heavy but rolls anywhere. Well worth the money. If you want it for professional karaoke this is it. You can change the lights and the lights are just amazing. I recommend listening to Phil Collin’s - In the Air Tonight, drum chorus. It will blow you away! It does hold a good charge which makes it portable. It connects easily to my phone. We had a get together at our house and it was the life of the party. Everyone wanted to hear their favorite songs and we just kept hearing how it was just like being at the concert. Phenomenal machine! ... show more

    • Great sound, loud volume, and easy to connect
Color: Black
I really like this speaker and would give it 5 out of 5 stars. The sound quality is great, it gets very loud, and it’s easy to connect to. Overall, it does exactly what I wanted and performs really well.The only minor downside for me is that the handles are a little awkward. They work, but they could be more comfortable or easier to grab. That said, it’s not enough to take away from how much I like the speaker.Between the sound quality, volume, and simple connection process, this is a great speaker and I’m very happy with it. I would definitely recommend it. ... show more

    • Our Family Has Purchased Three of These
Color: Black
This is our third JBL PartyBox Stage speakers in our family over the years and all are still in operation. We bought the third for our adult son's boat. We use these speakers primarily for backyard gatherings, family cookouts, holiday celebrations, boating, karaoke, and while working on outside projects. The biggest strength of the PartyBox Stage 320 is its ability to fill a large space with clear, powerful sound without noticeable distortion at high volume levels. Sound quality is impressive for a portable speaker. Bass is deep and punchy, but vocals and instruments remain clear even when the volume is turned up. Many portable speakers sound great indoors but struggle outdoors; they perform well in both environments. The battery life has been excellent for our uses. We can typically get through an entire afternoon and evening gathering without worrying about recharging. The built-in wheels and handle make it much easier to move around than its size would suggest. Pros: -Powerful sound with strong bass -Clear vocals and music detail -Long battery life -Easy to transport with wheels and handle -Durable construction for frequent use -Great for indoor and outdoor events Cons: -Large and heavier than a typical -Bluetooth speaker -Bass can be overwhelming in smaller rooms unless adjusted One reason we've continued purchasing this model is reliability. The fact that our family has purchased three of them over time speaks for itself. They have consistently delivered the performance we expected and have become our go-to speakers for entertaining. If you're looking for a portable speaker capable of handling backyard parties, family events, and larger gatherings, the JBL PartyBox Stage 320 is worth serious consideration. ... show more

    • The Beat Goes on !
Color: Black
My party speaker finally gave out after seven years, which I was actually pretty happy about since it was a gift. After it stopped working, I picked up this speaker as a replacement for family occasions. To my surprise, the quality is amazing—I really can’t complain. It’s very easy to connect to devices, and I love that it lights up while delivering great sound quality. I also ended up purchasing the case to go with the model I chose, and it looks great! ... show more

    • The Ultimate All-in-One Wireless Gig Rig for Performers The Ultimate All-in-One Wireless Gig Rig for Performers
Color: White
Review Image by Andy Goin
I bought the PartyBox 320 looking for a powerful, rechargeable speaker for gigs where reliable venue power isn't guaranteed, especially for outdoor shows. This has exceeded my expectations. The battery easily lasts through six to seven 1-hour shows on a single charge and juices up quickly when I'm in a pinch. Paired with JBL wireless microphones and my iPad via Bluetooth, it gives me a completely wireless setup. The dedicated microphone controls on top make on-the-fly mixing incredibly easy. Sound-quality is fantastic, offering crisp highs, clear mids, and impressive bass (with extra bass boost settings if you need them). Transport is a breeze thanks to the built-in handle and wheels; it’s surprisingly lightweight and fits perfectly in the trunk. It also mounts effortlessly onto a speaker stand. While I haven't tested the wireless multi-speaker pairing yet, it's a great feature to have. A phenomenal purchase—highly recommended for any mobile entertainer! ... show more

This thing is awesome! I got this on sale for $399 on black Friday and it is worth every penny! I originally bought this with the wireless JBL mics for karaoke, but I use it for everything now. Just so you know, I'm no audiophile nerd, but I used to work in the A/V department at Fry's Electronics (RIP) so I'm no rookie either. All that to say this thing thumps! The sound quality is great and the bass is awesome. With the push of a button you can turn bass boost on that hits hard enough to send any house pets you have into a terrified frenzy. It can run completely on battery power and has a removable battery that you can swap with a new one that will keep the fun going for hours longer. The telescoping handle and wheels are great too because this bad boy is heavy. The wheels are hard plastic that work well on a flat, hard surface. They will be absolutely useless on dirt or sand. The light show that is built into the speaker is a fun touch. The lights have different modes you can cycle through, or you can turn them off completely if you are trying to revenge scare your wife at 3am because she says she doesn't snore but in reality she sounds like a rabies induced warthog that is chewing on a stick of TNT. Sorry I should have saved that for my therapist. Anyways, It also has an app you can download that let's you control certain features from your phone. Overall if you're looking for a great sounding portable speaker and have some cash to burn, I highly recommend this one. ... show more
