Precautions while using Earphones
Impedance
Another aspect that users should consider before buying headphone amp is the relationship between headphone impedance and the output impedance of the amp. As a general, the output impedance of the amp should be much lower than that of the impedance of the headphones to get clear and tight sound. It is a good idea to have an output impedance that is at least ten times less than that of headphone impedance.
