JBL officially introduced the Boombox 4 in China. The new portable speaker continues JBL’s legacy of delivering powerful sound, long-lasting battery life, and rugged durability. With fresh upgrades and a smarter design, the Boombox 4 offers music lovers performance and portability in one package.
JBL Boombox 4 Overview
Immersive JBL Pro Sound with AI Sound Boost
JBL equipped the Boombox 4 with two larger woofers, two tweeters, and three passive radiators that produce its signature Pro Sound with more punch, clarity, and depth. The new AI Sound Boost feature analyzes audio in real time and optimizes the output, allowing the speaker to deliver higher volume with less distortion even at maximum levels.
All Day Battery Life: Up to 34 Hours
JBL extended the Boombox 4’s battery life significantly. The speaker offers up to 28 hours of playtime on a single charge, and activating Playtime Boost mode adds 6 more hours, reaching a total of 34 hours of continuous playback. This long-lasting performance makes it ideal for parties, trips, and outdoor gatherings.
Rugged and Durable Design
JBL designed the Boombox 4 to handle all environments. With an IP68 waterproof and dustproof rating, the speaker withstands beach outings, poolside fun, and hiking trips without taking damage from water or dust.
Two Bass Boost Modes
JBL offers two different bass experiences with this model.
- Deep Bass Mode: Adds a heavy and rich sound signature for deep beats.
- Punchy Bass Mode: Provides tighter and more energetic bass for upbeat tracks.
Users can switch between the two modes to match their music preferences.
Multi-Speaker Connection with Auracast™
Auracast™ support lets the Boombox 4 pair in stereo with another Boombox 4. It also connects with multiple Auracast-enabled JBL speakers to create a larger and more immersive sound field.
Bigger, Louder, and Lighter
The Boombox 4 has been redesigned to be larger and more powerful than the previous model, while also being lighter and easier to carry. The iconic handle design remains, making it highly portable.
Lossless Audio Playback
For listeners who demand the best quality, the Boombox 4 supports lossless audio playback through its USB-C port, provided the connected device supports it.
Eco-Friendly Materials and Replaceable Battery
JBL has focused on sustainability with the Boombox 4. The speaker uses post-consumer recycled plastic and recycled fabric for the grille. Its packaging is made from FSC-certified paper and printed with soy ink.
Additionally, the Boombox 4 comes with support for a replaceable battery (sold separately), which can be swapped in three simple steps. This allows owners to extend the lifespan of the product.
