Not happy

Coach cheer . 2 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 . 2 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

Great powerful portable speaker

MikePGH . 4 months ago

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.

How big of a room will this work with?

Answer from Customer Support1 month

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 Support1 month

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.

Do the white colorway on jbl party box 320 will get yellowish overtime?

Answer from Customer Support3 months

Thanks for your inquiry. White electronic devices, like our JBL PartyBox Stage 320, can darken over time due to several factors. This can be caused by prolonged exposure to sunlight or UV light, heat, dust and dirt, and chemical reactions, such as cleaners or pollutants. We recommend storing the speaker in a dry place and wiping the surface with a clean cloth to prevent dirt build up.
