Is the sound quality of Philips mp3 good?

At present, flying core chips are no longer used in Philips MP3, but Sigma chips are used the most. Because of the flying team's solo flight, Philips developed the patented sound effect "FullSound", that is, flying sound. There are comments about this sound effect on the internet, and I like it very much. It is suggested that the landlord personally audition, after all, everyone has their own taste.
