The JBL PartyBox 720 emerges as a formidable contender in the realm of high-fidelity party speakers, representing a significant evolution from its predecessors. This audio titan takes the beloved attributes of the PartyBox 520 and amplifies them, offering an expanded soundstage and deeper bass response. Designed to electrify any gathering, the 720 delivers an unparalleled combination of robust audio performance, dazzling visual effects, and versatile connectivity, catering to event organizers and music enthusiasts who demand nothing less than exceptional sound and atmosphere.
JBL's PartyBox series is synonymous with powerful sound and dynamic light shows, and the 720 continues this legacy with notable enhancements. Replacing the earlier 710 model, the 720 introduces a key upgrade: the option for a slot-in battery, offering true portability for the first time in this size category. This addresses a significant limitation of its predecessor, which was restricted to mains power. Furthermore, the 720 features larger 9-inch woofers, an increase from the 710's 8-inch drivers, resulting in a more profound bass presence. The inclusion of Auracast support allows for seamless wireless pairing with up to 99 compatible JBL speakers, creating an expansive, synchronized sound system. Dual XLR inputs expand its utility, accommodating microphones, guitars, or professional DJ equipment, making it a versatile hub for live performances or large-scale events. Despite its impressive capabilities, its substantial weight of nearly 35kg and considerable dimensions mean that while it can be wheeled around, long-distance transport may pose a challenge, particularly for smaller vehicles. The optional battery pack, priced around £150 for a twin pack, represents an additional investment for those prioritizing complete freedom from power outlets.
From a design perspective, the PartyBox 720 maintains the recognizable aesthetic of its lineage, featuring a sturdy black mesh grille and rugged matte black plastic construction. Its integrated carry handle and rubberized wheels facilitate movement, although its towering height of over two and a half feet underscores its formidable presence. Control over the speaker's functions is intuitive, with prominent knobs for volume and lighting effects, alongside dedicated buttons for Bluetooth pairing, Auracast, Bass Boost, and three programmable sound effects. The rear panel, shielded by a robust rubber cover, reveals a comprehensive array of inputs, including dual XLR/1/4-inch combo jacks, a 3.5mm AUX-in, USB-C, and 3.5mm in/out for wired daisy-chaining. The inclusion of an IPX4 splash resistance rating ensures durability against spills or light rain, making it suitable for outdoor use, though full waterproofing is not offered. The revamped lighting system features slim RGB bars along the top, bottom, and sides, complementing the large diffused figure-8 light strip around the woofers and smaller single-point RGB strobes. These lights are highly customizable via the JBL PartyBox App, offering six animation styles, extensive color options, and individual control over four lighting zones, all pulsating in sync with the music.
The audio performance of the PartyBox 720 is nothing short of exceptional. With a robust 800W output and newly enlarged 9-inch woofers, the speaker delivers an incredibly powerful sound that can easily fill vast outdoor areas. The sound signature is distinctly bass-forward, as expected from a party speaker, yet it retains a surprising clarity across the mid-range and detailed high frequencies. The ability to reach frequencies as low as 35Hz, further enhanced by the 'Deep' Bass Boost preset, provides a profoundly impactful low-end. The 'Punchy' Bass Boost mode caters to genres like rock, emphasizing lower mid-range frequencies, while 'Chill' mode reduces bass for a more relaxed listening experience. A 7-band EQ within the app offers granular control for audio customization, though the speaker's out-of-the-box sound is largely impressive for its intended purpose. Whether it's a driving rap track or an intricate drum and bass composition, the 720 reproduces music with an energy and fidelity that truly transforms any space into a vibrant concert venue.
The JBL PartyBox 720 truly shines as a speaker designed for grand-scale celebrations, offering a remarkable blend of high-fidelity sound, vibrant lighting effects, and extensive connectivity. While its sheer size and the optional battery's cost might be considerations, for those seeking to create an unforgettable auditory experience at large events, this device is a top-tier choice. It elevates the already impressive PartyBox lineage, making it an indispensable tool for turning any gathering into an electrifying party.
