JBL officially presented the new JBL Boombox 4 speaker in Brazil during an event held in São Paulo this Tuesday (05).

The launch reinforces the brand’s investment in portable audio equipment with high performance and prolonged autonomy, aiming to meet consumers who seek sound quality in various environments, whether at outdoor parties, family gatherings, or leisure moments.

Design and Visual Innovations of the JBL Boombox 4

With a robust design, the JBL Boombox 4 arrives as the direct successor to the Boombox 3 model, bringing enhancements in both design and technological functions.

Prolonged Battery Autonomy

Among the highlights, the battery autonomy of the JBL Boombox 4 stands out: according to the manufacturer, the device can play music for up to 28 hours without needing a recharge, depending on the volume and activated features.

This extended usage time represents one of the biggest differentiators of the new generation, especially for consumers who value mobility and freedom during use.

Additionally, the product offers charging via USB-C, facilitating connection with different types of chargers.

In terms of audio, the new JBL speaker features the AI Sound Boost feature, a technology based on artificial intelligence that, according to the company, can optimize sound frequencies, delivering clearer and more powerful sound without distortion.

Another differentiator is the traditional Bass Boost, which intensifies the low frequencies for those who prefer more vibrant and impactful sounds.

The two larger woofers, present in this edition, replace the previous subwoofer, providing even firmer and deeper bass.

Additionally, the side logos of the speaker also have integrated LEDs that can alternate between white and orange colors, contributing to the visual appeal of the product.

Weight, Resistance, and IP68 Certification

The JBL Boombox 4 model weighs approximately 5.9 kg and was developed to withstand the most diverse everyday situations.

To this end, the speaker has IP68 certification, an international standard that guarantees protection against dust and resistance to temporary submersion in water.

This feature allows usage in outdoor settings, even in the rain, at beaches, pools, and other places exposed to humidity and solid particles.

According to the brand, the device can remain submerged at a depth of up to 1.5 meters for up to 30 minutes without suffering damage.

Connectivity and Integration with Apps

In terms of connectivity, the speaker offers compatibility with Bluetooth 5.3, ensuring quick and stable pairing with different mobile devices, such as smartphones, tablets, and laptops.

The product also supports the JBL Portable App, a proprietary app that allows to adjust audio settings, update firmware, and customize the user experience in a practical and intuitive manner.

Extra Features and Functions for Parties

Another relevant point is the ability to pair multiple JBL speakers simultaneously through the PartyBoost function.

This feature allows for amplified sound power and creates immersive environments, making the JBL Boombox 4 an interesting option for large parties and events.

The company also highlights that, in addition to playing music, the speaker can be used for answering hands-free calls, as it has an integrated microphone with noise-canceling technology.

In design, JBL maintained the tradition of creating resilient products but with touches of sophistication.

The rubberized finish, the reinforced metal grilles, and the ergonomics of the handle are points highlighted by the brand, which seeks to balance durability and modern aesthetics.

The speaker is available in black, camo, and green colors, expanding choices for different consumer styles.

For those concerned with sustainability, it is worth mentioning that JBL informed during the launch event that part of the materials used in the manufacturing of the Boombox 4 comes from recyclable sources.

This initiative is part of the company’s global commitment to reducing the environmental impact of its products.

Market Availability and Competition

Although it has not officially revealed the suggested price for the Brazilian market by the closing of this text, JBL emphasized that the model will reach the main electronics stores in the country this August.

The expectation is that the JBL Boombox 4 will compete with other premium equipment in the segment, such as the Sony SRS-XG500 and the Ultimate Ears Hyperboom, known for their high power and resistance.
