JBL XTREME 4 Portable Bluetooth Speaker (BLACK)
This listing includes only the main unit and the outer box.

◆Extreme Sound Enters a New Dimension
Equipped with AI Sound Boost, a next-generation amplifier technology that maximizes speaker performance.
Using AI algorithm technology, it predicts the movement and power response of the loudspeaker while simultaneously analyzing the input signal in real-time.
It maximizes the potential of the drivers and fully utilizes the dynamic range to deliver high-quality, powerful sound.
By reducing sound distortion even at high volumes and maximizing low-frequency output and overall volume, it achieves an unprecedented new dimension of powerful sound.

◆Durable Design for Outdoor Use with Excellent Portability
Complies with IP67*1 dustproof and waterproof standards. You can use it with confidence in outdoor settings where water and sand are a concern, such as riverside camping or the beach.
In addition, the durable casing is equipped with shock-absorbing bumpers made of impact-resistant material on both sides and the bottom.
While the previous model covered the edges of the casing at three points, this model has been reinforced to four points and also includes protection on the bottom, safeguarding the unit from impact in case of accidental drops.
