Product is really good. Sounds clean and it’s almost perfect. Only issue I noticed is when I pair with another speaker, there’s a slight clicking noise with the base. But when I unpair, the noise goes away. Not a huge deal because it’s loud as all heck, but it’s nice to pair when I’m outside and have a smaller speaker inside.

This JBL party box is amazing

Joeypgood . 1 month ago

I bought this party box as a second one for my second house. I had to haul my old one back home because I needed it for a wedding. I used to be a DJ but didn't feel like hauling all of my equipment out to a wedding. So I just used the Party box 320 and my phone was the player. We rocked the place with over 100 people. Plus used it cordless for the pastor to perform there wedding. I had never tried turning it up that loud but can it rock! Thanks JBL. Would have bought the 710 but it wasn't battery powered. Love that the 320 is battery. Also used it rocking for about 10+ hours and still had battery left.

Exceeded Expectations

Russ23 . 2 months ago

I had used this about 3 or 4 times for a few hours each and I am really impressed so far. The sound is awesome, great bass, and the battery has not needed a recharge yet. I have not really cranked it up too loud, but overall, it has surpassed my expectations

False advertising!!!

Ethan06 . 2 months ago

Audio is great, but the battery life is nowhere near what they claim. Haven’t even had mine half a year and the speaker lasts maybe 2 hours constant playtime compared to their alleged 18 hours. It’s always had 2-2.5 hour battery life since I got it and it’s aggravating when they claim it can be on constantly for 18 hours but mine doesn’t even make 3. Either my product is faulty or they need to work on how they advertise this product.

volumen non controled via Bluetooth from smartv

Marlonv . 5 months ago

the sound is EXCELLENT but I found a detail when I tried to raise and lower the volume from my Samsung smartv when I connect the pathtybox to the smartv via bluetooth and it did not work,,, you can only raise and lower the volume from the speaker directly... I called technical service several times and they did not give their solution,,,I had to return it..I want to raise and lower the volume of the speaker from my smartv when it is connected via bluetooth...let me know when you have resolved this detail.

Can these be wall mounted or mounted?

Answer from Customer Support1 year

Thanks for your inquiry. Our JBL Partybox Stage 320 can't be mounted on a wall or a tripod. You may want to check out our JBL Partybox 110 which contains a 36 mm receptacle cup to allow mounting on tripod stands or on a pole over subwoofers. If you need more help, please contact our customer support.

When will the replacement battery be available? I love the 320, battery runs 4 hours with volume at max. I really need an additional battery 🙏🏼

Answer from Customer Support1 year

Thank you for your question. Our JBL PartyBox Stage 320 has a maximum playtime of up to 18 hours. Please know that volume and usage can affect the battery's life. In addition, the battery wears out over time. Even if listening at maximum volume to heavy bass music, the battery should last longer than 60% of the published playtime. Please contact our customer support for further assistance. Also, the batteries will be sold as a part and as a finished good, and the finished goods are estimated to arrive in July.
