It will be easy to enjoy high-quality sound be it at a party, going outside, or at home, the Boombox 4 will deliver a deep and commanding audio quality.
Overview

Design and Buildup
The design is based on the iconic boombox design of JBL and has a powerful built-in handle and a rough shell. Although it weighs about 5.89 kg, it is solid, balanced and upscale. The body utilizes hardy materials that can withstand tough outdoor environmental conditions and yet have a sleek look on the black, blue or even a camouflage color choice. The IP68 level of protection makes it resistant to dust, dirt, and water, to take it anywhere without any concern.

Sound Quality
The strength that the Boombox 4 has is sound quality. With its 7-driver system with woofers, tweeters, and passive radiators, it provides the sound with enormous volumes and a powerful bass. The AI Sound Boost option is a real-time audio analysis feature that focuses on improving clarity and loudness and minimizing distortion of your music. Having two types of bass, Deep Bass and Punchy Bass, you can adjust the sound to the way you prefer to listen. Be it EDM, hip-hop, or classic rock, the sound output is very clean, powerful and it immerses you.

Battery Backup
The other impressive feature of the Boombox 4 is battery life. It will have a maximum of 28 hours of continuous playback and with Playtime Boost it will take 34 hours depending on the use and the level of volume. It is charged via USB-C and it will take approximately 3 hours to charge completely. The enormous internal battery also enables the speaker to be used as a powerbank, which means the ability to charge phones or other devices at the same time.
Connectivity and Features
The speaker advocates in favor of Bluetooth 5.4 which would be more stable, fast, and efficient. Auracasttm is compatible with several other speakers that can be linked together to play audio in the same environment over a wide area. It also has USB-C lossless audio, and you can play digital audio off your device without having to use Bluetooth compression. There is neither an aux port as the traditional, however, the more advanced connectivity options compensate. JBL Portable app gives more control over EQ, updates and sound modes.
