Hi,
I think the difference in the audio response (such as the "click clack") may
be attributable to differences in sensitivity and impedance.
At work I used to use some YH-1 Yamaha headphones but switched to a
Sennheiser HD 280 when they reconfigured our office since the HD 280 have much
better external sound attenutation.
I used to plug my headphones directly into the headphone output on the front
of my desktop computer. With the HD 280 I can hear a very faint hum (kind of
like a 60hz hum but at a much higher audio frequency) but only when I move the
mouse cursor. With the Yamaha headphones the hum is inaudible. I've had some of
my coworkers listen and they can also hear the difference...
I'd compare the impedance and sensitivity figures if you can find them...
I've used the HD-280 with my Orion I and don't have an issue with the "click
clack" noise.

I just discovered something that might be of general interest. Using
theSennheiser HD-202 phones the "click clack" of CW keying when sending
isannoying, but with the Radio Shack Titanium Phones, it is not
audible...Hmmm... So what is the difference?RonKA7U -----Original

PMTo: TenTecReflectorSubject: Sennheiser HD 202 w/ handi cable clip Having
faithfully read the numerous posts on head phones a while back onthis
reflector, I decided to take a chance on the Sennheiser HD-202 headphones.
Prior to these phones I have been using the Radio Shack Titaniumstereo
headphones. So here is my 2 cents... The HD-202 phones seem to have a bit more
"punch" especially at the lowfrequencies and therefore make cw easier to
"hear". they seem to block outroom noise to a greater level then the Titanium
phones. The HD-202 phonesare much warmer to wear and this becomes
uncomfortable in short order attemperatures above 69 degrees F., whereas the
Titanium phones are cool andlight to wear. So in conclusion, I recommend the
Sennheiser HD 202 phones with the hadicable clip, for serious attentive
listening, and Radio Shack Titanium phonesfor extended listening under less
stressful conditions. Maybe a pair of Sony ear buds would be cool and
effective, once I got overhaving my ears filled.RonKA7U
