Thanks for reaching out. Connecting a speaker to a TV over Bluetooth often causes audio delay, unlike connecting to a mobile phone or tablet. This happens because TV Bluetooth hardware processes audio and video separately, which takes longer than on a smartphone or tablet. To help sync the audio with your screen, try checking your TV's sound settings for Audio Delay, Lip Sync, or SPDIF Delay. Alternatively, if your TV has an AUX output, connecting a 3.5mm cable directly to your PartyBox Stage 320 will give you perfect sync.

Great sound quality

The JBL PartyBox Stage 320 has completely exceeded my expectations. After using it for three weeks, I can confidently say it’s one of the best purchases I’ve made. The sound is powerful, clean, and full of life the kind of bass that fills a room without distortion and vocals that stay crisp even at high volume. It genuinely transforms any gathering into a proper event.

Big Speaker, Big Sound

I purchased two JBL PartyBox Stage 320 speakers for a large outdoor party, and they exceeded my expectations. Setup was quick, and pairing the speakers together using Auracast took just a few seconds. They stayed perfectly synchronized throughout the event, including the lights, which added a fun touch once the sun went down. We had guests spread across several acres, and the sound coverage was outstanding. The music remained clear no matter where people gathered, and the bass was powerful without overpowering the vocals. Even at higher volumes, the sound stayed crisp and balanced across every genre we played. One unexpected bonus was the waterproof design. During the party, a strong storm rolled through before we had a chance to move the speakers under cover. Both Stage 320s were exposed to the rain, and they continued performing flawlessly without any issues. It gave me a lot of confidence in their durability for future outdoor events. The battery life was excellent, easily lasting through our event without needing to recharge. Between the impressive sound quality, long battery life, rugged build, and seamless Auracast pairing, the PartyBox Stage 320 is an outstanding speaker for everything from backyard gatherings to large outdoor celebrations. I highly recommend it to anyone looking for powerful, portable sound with exceptional performance.

Expected more

I bought this to use for my out door fitness classes, great sound quality but it really wasn’t as loud as I thought it would be for out door use, I also found it extremely heavy. Would be more suited for an indoor small hall.

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.
