JBL PartyBox 720: A New Benchmark for Battery‑Powered Party Sound

JBL has unveiled the PartyBox 720, marketed as the company’s largest‑ever battery‑powered party speaker. The unit is physically larger than many human children and delivers a formidable 800 W of audio power. Its driver configuration includes two 9‑inch woofers paired with a set of 30 mm dome tweeters, providing robust low‑frequency punch and clear highs.

The speaker incorporates JBL’s proprietary AI Sound Boost technology, which amplifies volume without introducing distortion. Connectivity options are extensive, featuring multi‑speaker linking via Auracast, a USB‑C port for direct streaming, and XLR inputs that accommodate microphones, guitars, or DJ consoles—making it suitable for karaoke and live performance setups.

Visually, the PartyBox 720 offers a “futuristic lightshow” that synchronizes with the music. Its internal battery is replaceable and can sustain up to 15 hours of continuous playback. JBL has set the retail price at $1,099, with pre‑orders already open and shipments scheduled for September 21.

JBL Boombox 4: An Iterative Upgrade with Extended Runtime

Alongside the PartyBox, JBL introduced the Boombox 4, an evolutionary update to the Boombox 3. The new model retains the AI Sound Boost system, delivering louder sound without distortion, while shedding nearly two pounds and becoming almost two pounds lighter than its predecessor.

The Boombox 4 is built to withstand harsh environments, boasting an IP68 rating for water and dust resistance. It also supports Auracast for linking with other speakers, and its replaceable battery promises up to 28 hours of playback before needing a recharge.

Pricing for the Boombox 4 is $550, and it will be available in three colorways. Pre‑orders are currently open, and the device is slated to ship on September 28.
