I feel that I got a fair deal overall with my transaction. It is true that the 33rd Sonya has a price tag that is 3,000 higher than the rival Charge 4 model, however this represents an overpayment for the following features: Protection against water, dust, and shaking to the fullest extent possible The availability of options that are less expensive Bluetooth 5.0, as well as LDAC and AAC codecs of a greater quality Design with some soothing music, in case anyone is interested. A volume level that is greater than that of the Charge 4 (compared live, but there are tests on YouTube) To everyone their own when it comes to sound. In my opinion, Charge has a more prominent bass presence, but for my taste, the bassiness is already excessive. You can only listen to bass tracks from contemporary hip-hop artists on it. Sony is more adaptable, and it contains a wider variety of sounds in addition to bass. In addition to this, turning the extra bass mode on or off has a significant impact on the overall sound, and the equalization that is included in the companion app allows me to customize the speaker to match the genre of music that I listen to.
