Hi Bernie

I use Yaesu YH77STA with my K2 (2746) and I love them, I am not sure what
Pro's and Cons you refer to but I prefer a light pair of phones and these
are ideal from my point of view, the only other pair of earphones I have
used on the K2 were Heil and I found those to be very claustrophobic  if
that is the correct word they shut everything out!

Bernie, etal,

Yaesu YH77STA headphones are lightweight
and very comfortable.  I have used them for
many years at home as well as on DXpedition
with a K2 working those gruelling 3 to 4-hour
shifts of pileups.  I don't wear them covering
my ear but pushed slightly forward.  Great
sound from those beautiful CW tones.  I have
no idea how they sound on that other mode.

Do you know what the frequency response of these 'phones is?  Are they
the usual 20Hz - 20Khz "hi-fi" type, or do they have a more limited
response, like 100-5000 Hz?  I am looking for a comfortable set with a
communications-type response.

Icom has some light weight communications type head phones. I think the
receiver section of the icom page will find them.

The trouble with these is that they are monaural.  Stereo is important
because I want to investigate binaural modes for CW, such as putting the
I and Q outputs of a quadrature sampling detector into each ear, etc.

The Yaesu phones are stereo but the frequency range is important so I
can get rid of the external DSP I'm using to kill sidetone thumps and
clicks.

I sometimes plug my YH77ST headsets into my PC phones out, which
is stereo, and put a music CD in the drive and listen to some great stereo
music.  I don't know about the 20Khz upper response but the "highs" and
"lows" I hear are quite high fidelity.  Certainly much broader than the
100-5000HZ.  Plus, they are amazing CW receptors as well.

I use the KOSS PortaPro headphones.
I found them to be lightweight and easy to drive with low audio.
Also easy to collapse for that mountaintrip or camping.
Very nice audio.
Low cost quality , at least here in Norway.

Hi Vic;

You can build a roll off filter with some caps and an inductor or two. Look
at an old "ARRL Handbook" for this info. I'm not sure if the newer Handbooks
cover this topic.
