1. Check the audio source. If you are already listening to high-quality or lossless music, or if the track does not contain much high-frequency detail, the difference may be subtle or hard to notice. Try switching to different songs or lower-bitrate audio to better evaluate the effect.

2. Consider differences in audio perception. Music is a very subjective experience and everyone hears details differently. Some people may notice the enhancement more clearly than others.
