Testing

Low:

Song: <<Gu Shi>>

Good reverting ability to reality. Clear, elastic and powerful sound of drums reflects their richness. It performs well in quick rhythm without lengthy expansion.

Mid:

Song: <<Du Kou>>

Thickness of human voice could be found in the earphone performance. But lows are not shown powerful enough in this song. It seems that the high frequency is over low and mid ones..

High:

Song: <<Mutter-Violin>>

Good performance in high frequency as a whole. Sound is clear. Its demonstration is very clean and delicate when it is solo; magnificent when it is symphony.

Conclusion: It is balanced as a whole. It leaves great impression for us by its mid and high frequencies. Its unique sounding unit makes the earphone outstanding in sound field.
