About this product

- The required output of a suitable charging device is 1W minimum and 79W maximum.
- This product supports PD fast charging (harmonised fast charging).
The JBL PartyBox 320 is a serious party speaker with enough power and presence to fill a space the size of a tennis court, whether you're hosting indoors or taking the energy outside. With 240W driving two 6.5-inch woofers and a pair of 25mm dome tweeters, you get deep, clean bass that stays tight even when you crank the volume, plus crystal clear highs that cut through the mix. It's not just about sound, there's a built-in lightshow with starry effects, light trails, and strobes that sync to your music, turning any gathering into something properly memorable.
The battery lasts up to 18 hours on a single charge, so you can party from dusk till dawn without hunting for a socket, and if that's still not enough, the battery's replaceable so you can swap in a fresh one and keep going. Need a quick top-up? 10 minutes of fast charging gives you another 2 hours of playtime. Connectivity's covered with Bluetooth and a 3.5mm AUX input, and you'll need the JBL app to unlock all the features. It weighs in at a substantial size for big sound, and it comes with the battery included plus a 2-year manufacturer's guarantee.

Awesome speakers... so good I bought two!
Awesome speakers... so good I bought two! I bought the 320 first and then a 520 to use at a family party and after the party I was so impressed with both I decided to buy a second 320 speaker so I could use them at home as a 'stereo' pair for streaming my music... 100% recommended for a great sound and customer experience from JBL/Harman.

I've sampled quite a few party speakers and the JBL is the best in my opinion, musical separation, bass, vocals, the quality is superb.

Great sound
Really great crisp sound. Still figuring out how to refine the bass. Should probably read the instructions! I have to regularly lift it into my car to teach zumba classes and do find it a bit on the heavy side. But all in all a sturdy snd impressive speaker

Fantastic power, can’t turn it up all the way.
Bought my partybox 320 about a month ago, the battery life is awesome and is more than sufficient for a 6 to 12 hour party, I only hope it will continue through time. The sound clarity is full and impactful and bass pumps, but I can’t turn it up all the way 🤣 (as if that’s a bad thing) 🤣 All in all I am very happy with this product, portability is spot on with the handle and wheels. Would be awesome if they created a swing cradle for it so we can hang it up high. But love this, worth every the money.

Great sound. It really is a great speaker.
Really good sound. Very happy with the speaker. I wasn't sure if I should have gone for the 520 but I think this is enough for what I need!! Even the 320 isn't particularly portable so glad I didn't go for anything bigger!

Having checked I can see this does have a USB connector so provided your TV has a USB port you will be able to connect this to the TV.
