Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20,000 Hz
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
Input Impedance
This is the input impedance of the headphone amplifier.
16 ohms
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
