Easy to set up

Stephanie421 . 1 month ago

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.

Not happy

Coach cheer . 3 months ago

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 .

Great speaker with one flaw

Cstaats . 4 months ago

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

What does it mean by fast charging the speaker?

Answer from Customer Support13 days

Thanks for your question. Fast charging means the JBL Partybox Stage 320 can recharge more quickly than normal when using a compatible fast‑charging power adapter. Please ensure your power adapter is rated for 5 V / 2.1 A to enable faster charging.

Instead of holding a microphone, I want to know if there is a headset w\microphone that can be used so we don't have to hold a microphone when speaking. We have the JBL PartyBox Stage 320

Answer from Customer Support20 days

Thank you for your inquiry. We understand that it's convenient to have a headphones with mic than holding a mic itself. While our JBL PartyBox Stage 320 doesn't support connecting headphones (even those with mics) for voice input, wireless microphones can be used for it. We appreciate you sharing this feedback. This will help us improve our products in the future.

How big of a room will this work with?

Answer from Customer Support2 months

Thank you for your inquiry. We do not have a specific measurement for how wide our JBL Partybox Stage 320 can play music. We can say that the speaker will perform in a room larger than 50 square meters. However, it still depends on how crowded the space is.

can the party box be connected to the jbl boom box

Answer from Customer Support3 months

Thanks for your question. Yes, it will connect via the auxiliary wired connection. However, due to the JBL Boombox's smaller size compared to the Partybox Stage 320, you may notice a difference in sound volume. For optimal performance, we recommend using speakers with a similar wattage output.
