Adjust the overall volume with the volume knob of

ambient sounds by using the audio source volume 
control.

Tip:

 

For the audio source to be louder than the ambient sounds, turn up the volume on the audio 

source and reduce the EAR3MK2 volume. The following table give some examples on how the 
ambient sounds (EAR3MK2) and the audio source affects the desired output volume.

Using these combinations, the ambient sounds and audio source can be fine tuned to suit your 
personal listening preference.
