Kenwood HS 5 Headphones
 

I am using Kenwood headphones, HS 5. Anyone using them know that they
are mono and not stereo...I have also noticed that these headphones
are not as loud as others I have tried.
I was wondering if replaceing the mono plug with a stereo plug would
make any difference, has anyone tried this? This should also increase
the impedance to 16 ohms as both headsets are in paralell. The other
question is, would this have any adverse affect on the audio output
transistor? Jim
