I think it's better to use portable speakers, because the current radios are almost out of date, and the sound quality of portable speakers alone will not be worse than that of radios. And when the portable speaker comes out to listen to the radio, it can also be plugged in to listen to music MP3.

As a speaker, it now provides many services. For example, Yalan Shi has been using the sound library to provide content services since the fifth generation of 225. These are all functions that the radio does not have.
