Testing

Low:

Song: << Gu shi >>

The sound of drum does not attractive and dive deeply, which makes people feel so dull, without the boom-boom  feeling.

Mid:

Song: << Du kou >>

Tsai Chins voice seemed to be somewhat not powerful. The low tune listens no perfect, which made all the voice a little float.

High:

Song: << Orchestra-denon >>

The earphone performance well in the high volume, and doing well in the sound reduction and details. You can hear the granular sensation of violin.

Conclusion: The open design makes the voice so natural, the voice is generally cline to the resonant Pitch. The good performance of strong sound analysis and high pitch give you a good feeling when you listen to the symphony and solo instrument playing. The impedance is low ,also  the sound is low.
