Just a day after JBL announced its new ultra-portable speaker, the JBL Grip, come another two new speakers from the brand. The audio maker just launched the Boombox 4 and the PartyBox 720 — the latter the largest speaker yet from JBL.

The JBL Boombox 4 is an update to its predecessor, the Boombox 3. It’s designed to be portable with the top handle, but it’s a hefty speaker. The new model comes in at 13 pounds, two pounds lighter than the Boombox 3. It’s a master of bass with two different Boost Bass settings: Deep Bass adds a rich bass performance while Punchy Bass is for lively, upbeat tunes.
In the redesign of its Boombox, JBL added two new woofers to the speaker. It offers 28 hours of playback and an IPX68 waterproof rating. The Boombox 4 also comes with AI Sound Boost to deliver a louder sound with less distortion. JBL’s Auracast also allows you to sync the Boombox with another speaker, like the new PartyBox 720. Preorders for the Boombox 4 start now and will be available on Sept. 28.

JBL’s PartyBox 720 is the largest battery-powered speaker from the brand, making it a step up from the JBL PartyBox 520. It stands 37 inches tall and weighs a whopping 68 pounds, so while it is portable thanks to its handle and wheels, it’s going to be a heavy lift.
It’s a party speaker fit for true entertainers looking to blast music for a crowd. It has the convenience of being wireless, able to play wherever you need, without being tied down by the need for an outlet. With 15 hours of playback, it can keep the party going from dusk to dawn. Two nine-inch woofers deliver powerful sound and bass. Like the Boombox 4, it also uses AI Sound Boost and Auracast.
It features two XLR ports for a microphone, guitar, or even DJ equipment. As evidenced by our experience with the PartyBox 520, we think JBL’s speakers make for great karaoke machines when paired with a mic. The JBL PartyBox 720 is available for preorder now and will be on shelves Sept. 21.
