The JBL PartyBox 720 is marketed as an ultra-large party speaker, priced at £799.99. It promises top-tier sound quality, impressive lighting effects, and versatile connectivity in its class.
The unit is the successor to the PartyBox 710. A key upgrade is the introduction of a removable battery design, allowing this previously mains-only speaker to be used outdoors. However, this battery must be purchased separately, requiring two JBL 600 batteries, which cost around £150 for a set.
In physical terms, the PartyBox 720 is substantial. It stands over 2.5 feet tall and weighs nearly 35 kilograms. While it features a top handle and rubber wheels to aid short-distance movement, its sheer size may complicate fitting it into a car boot. The unit holds an IPX4 splash-proof rating, offering protection against minor spills, but not against rain or full immersion.
The design maintains the classic look of the series, featuring a black grille and a prominent JBL logo on the front. Controls are housed on the top panel, including volume knobs, lighting controls, and a dedicated Bass Boost button. The rear connectivity options are extensive, incorporating dual XLR/1/4-inch combo inputs for microphones or guitars, a 3.5mm AUX input, a USB-C port, and 3.5mm input/output jacks for wired daisy-chaining.
The lighting system is described as a hallmark of the range, featuring multi-zone RGB light strips and strobe effects that pulse in sync with the music. Users can manage these features via the JBL PartyBox app, which allows fine-tuning of a 7-band equaliser, switching between various sound and lighting modes, and controlling the four distinct lighting zones individually.
Connectivity is versatile through Bluetooth 5.4 with Auracast support, enabling wireless daisy-chaining of up to 99 compatible JBL speakers. Sound quality is noted as a major strength. Equipped with two 9-inch woofers and two 1.25-inch tweeters, the speaker delivers a total output of 800W, with bass extending down to 35Hz.
The sound energy is immense; even at just 20% volume indoors, it may be loud enough to disturb neighbors, possessing enough power outdoors to transform an entire garden into a club. Despite its powerful and bass-heavy tuning, the midrange remains clear for vocals, and the treble retains good detail. The built-in Bass Boost mode offers both “Deep” and “Punchy” presets.
The reviewer concludes that the PartyBox 720 excels in sound and lighting, alongside flexible connectivity. Nevertheless, its immense size, substantial weight, and the necessity of an additional battery purchase are significant factors. Consequently, it is recommended only for users who require extreme volume and deep bass for large events. For those prioritizing portability or using it as a routine home speaker, the smaller PartyBox 520 may be deemed more sensible.
