  • Great sound and long battery life
Color: Black Size: JBL PartyBox Stage 320
This speaker is great! It is super easy to connect to your phone, the wheels make it very easy to move around and the battery last forever. The sound is great and it can get very loud which is perfect!

  • oh my gosh….
Color: Black Size: JBL PartyBox Stage 320
Writing review from my mothers amazon account: What is there not to like about this speaker?? Insane light show, DEEP BASS, Cool touch features on top + mic compatibility, extremely loud sound quality and took me about 10 seconds to connect to it.. I bought the Jbl on the go 100 speaker and felt that it wasn’t loud enough, maybe for an inside relaxed party that needs something louder then your average hand speaker but if you really want to ROCK the party you need this. It’s almost too loud, i don’t see a world where you need something louder then this and if you do you’re definitely going to be suffering from hearing loss. This sound quality just blew me away. Both of my parents were surprised at how loud this speaker was and told me to refrain using it at max volume as I may get kicked out of my campus apartment lol. I was skeptical about the steep price but seeing the quality of the lights, sound, base, features i truly think it’s worth every penny and i’m honestly scared to hear how loud the 710 and 1100 versions are lmao. The only con i’d have to say is it’s heavy as heck, thank god it comes with wheels because i really couldn’t imagine lugging this thing around as it feels like a 40lb dumbbell and that is because it’s 40lb lol.. Overall this speaker is a no brainer to buy if you really need loud sound for a outside get together and if your playing this inside you will certainly have people saying “who’s damn speaker is that it’s so loud” 1000/10 ... show more

  • JBL PartyBox Stage 320: The Ultimate Portable Party Companion
Color: Black Size: JBL PartyBox Stage 320
The JBL PartyBox Stage 320 is a fantastic portable party speaker that lives up to its promise of delivering a fun and immersive experience. Its powerful JBL Pro Sound is exceptional, providing crisp highs, punchy bass, and excellent clarity, even at high volumes. This makes it ideal for parties, gatherings, or outdoor events where powerful audio is essential. The futuristic lightshow is a real crowd-pleaser, with dynamic LED lights that sync to the music, creating an engaging and energetic atmosphere. The lights are customizable, allowing you to tailor the experience to match the vibe of your event. In terms of portability, the telescopic handle and wide, sturdy wheels are standout features. They make the speaker easy to transport, even over uneven surfaces, which is perfect for outdoor parties. The splash-proof design adds to its versatility, ensuring it can handle accidental spills or light rain without worry. With up to 18 hours of playtime, the PartyBox Stage 320 is reliable for all-day or all-night use. The battery life is impressive, and it charges relatively quickly, so downtime is minimal. The only slight drawback is its size—it’s not as compact as some smaller speakers, but the handle and wheels make up for this. Additionally, while it’s perfect for parties, it might be overkill for those looking for a simple, everyday speaker. Overall, the JBL PartyBox Stage 320 is a powerhouse designed for those who want bold sound, vibrant visuals, and a portable, durable design. It’s a must-have for party enthusiasts and event organizers looking to take their celebrations to the next level. ... show more

  • The Beat Goes on !
Color: Black Size: JBL PartyBox Stage 320
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

  • Love this speaker.
Color: White Size: JBL PartyBox Stage 320
I cannot believe how loud this thing gets. Wonderful, consistent sound with zero distortion. I am in no way an audiophile, but it sounds amazing to me. Simple to connect to Bluetooth, and easy to move around. Highly recommend.

  • Glad I bought!
Color: White Size: JBL PartyBox Stage 320
Sounds amazing!!!. Bass is impressively deep. Good all around sound quality. Wish it were a little louder. Superb quality of build, feels solid and very durable. Light show is awesome. Want another one to pair up to get more stereo effect and to maybe have louder volume.

  • Last kind of speaker I’ll ever need.
Color: Black Size: JBL PartyBox Stage 320
I normally don’t write reviews but if you’re guessing on whether to get this, this is the one! I started from the JBL flip 4, Xtreme 2, and now on to currently using this 320. This thing is a beast and super loud! Loud enough to cover entire tennis court, as stated on the official website. I also bought a cover bag for this where I can carry it like a backpack. I don’t need any more speaker larger than this. THIS IS IT. ... show more
