However, it does not support wifi connection. This limitation makes it more difficult for users to experience the sound. Sony relies only on a set of strobe lights to determine whether the volume is in the middle, lowest, or highest.

Besides, the speaker also supports standard connections such as HDMI ARC (plug-in TV) or Optical to help you expand the entertainment space more convenient and diverse.
