AI Sound Boost technology on Xtreme 4, as announced by JBL, will use AI algorithms to analyze music sources in real time, then optimize the sound output, delivering powerful and less distorted sound. more sound. Indeed, the speaker has the ability to optimize sound quite impressively. For example, when used in a closed room, the speaker automatically lowers the bass to a certain level, while the treble is clearer.

In fact, I have not had any “drinking sessions” all night long for 24 hours to test whether Xtreme 4 can still withstand the information announced by the company or not.
