[TenTec] Sennheiser HD 202 w/ handi cable clip

[wa3fiy at radioadv.com]

The Sennheisers may be more sensitive than the Radio Shack Titaniums or 
the impedance of the Sennheisers may be lower causing more power to be 
delivered at the same VOLTAGE output at the headphone jack.  An easy 
test would be to insert several hundred ohms in series with each channel of 
the Sennheisers and see what happens.

 I have a rather severe hearing loss and still need to add in the range of 
200 to 400 ohms in series with my low impedance headphones.  I just put 
1/4 watt resistors in the phone plug.

The ideal situation as I see it is to have sufficient headphone
attenuation such that when operating the receiver at a volume level near
distortion, the sound in the headphones is just at the edge of being
uncomfortably loud.  This will reduce low level audio noise, clicks, pops 
and all that other stuff and as a bonus, will prevent accidental dangerously 
loud audio blast.
