K3 Which headphones for stereo cw work?

I know there has been a recent thread about headphones,
but this time I would like to focus on just the receive aspect,
as I need to buy a set of 'cans' for use 90% use with cw.

What I am really confused by is the K3's stereo rx capabilities,
with *ONLY* the main receiver.
(Looks like the headphones cost a 1/3 as much, as the 2nd receiver will)

Does the Heil Proset allow for the stereo (separate channels)?
It doesn't specifically say so.....
but the Heil Proset Plus does mention stereo

Here is the Heil Proset:
http://www.heilsound.com/amateur/products/proset/index.htm

"Besides sealing out noise passively, the Pro Set now includes Heil Sound's
exclusive phase reversal technology, which allows the user to "move" the
incoming signal by engaging the phase-reversal switch; this creates a unique
spatial widening sound that can, in some situations, significantly improve copy
in a tough DX pile-up."

"The earphone speakers in the Pro Set Series are 200too-Ohm devices, with a -3
dB point at 8000 Hz. This combination reduces a lot of the hiss found in
receiver audio stages. These speakers exhibit medium sensitivity, but they are
easily driven by most rigs if you turn the AF Gain control up to about 2 o'clock."

==

Here is the Heil ProsetPlus:
http://www.heilsound.com/amateur/products/prosetplus/index.htm

"The Pro Set Plus is wired in a stereo configuration, making them easy to
integrate into your SO2R station, and ideal for rigs like the FT-1000D that have
a "Balance" control for Main and Sub receiver audio levels."

"Also provided on the Pro Set Plus is Heil Sound's exclusive phase reversal
technology, which allows the user to "move" the incoming signal by engaging the
phase-reversal switch; this creates a unique spatial widening sound that can, in
some situations, significantly improve copy in a tough DX pile-up."
===

I don't plan to operate voice, so I really don't need a mic attached,
but it would seem those 2 headphones are among the best as far as long term
comfort and ability to do stereo and noise reduction.

Are there any other headphones the group would recommended for cw and taking
advantage of the K3's stereo capabilities?

I guess if I have to have a mike included I'll just have to deal with it. ;-/

Re: K3 Which headphones for stereo cw work?

Sam,

With the K3's excellent receive EQ capability, you can tailor the receive
sound most anyway you want, with most any headphones you want.

The Yamaha CM500's are very popular and cost a ton less than Heil. I have
both the Yamaha and Heil and switch back and forth - they both have their
plusses and minuses. I also use Shure E2C earphones (insert into the ear
canal) for a change of pace and to reduce ear fatigue. Watch your levels
though with any of these.

I would suggest finding headphones that you find to be most physically
comfortable at a reasonable price and then use the K3 EQ to suit your ears.

The Yamaha CM500's are probably the best bang for the buck.

Yes, just like the Proset Plus. But I prefer the latter as they seem more

Re: K3 Which headphones for stereo cw work?

In reply to this post by k5oai

Sam,

I am not certain why you looking only at Heil. Their products are
somewhat overpriced IMHO.
I suggest you go to a place that deals in consumer audio - Best Buy,
Circuit City, or even Target stores (Sam Ashe too) and look at what they
have. The popularity of iPods and other such devices have made decent
headphones readily available and at a variety of prices ranging from
inexpensive to very high dollar.
Find a set of headphones that fit your ears and feel like they will be
comfortable after wearing them for a while.
If they sound good listening to music, they will sound good on the K3
too. If you want to customize the response of the K3, that is what the
RX EQ is for - use it instead of spending a great price for so-called
"communications" headphones.

The wireless models free you from the attached cord problem and give you
freedom of movement, but before deciding on one of those, check the
store's return policy - you will want to return them if you have
problems with RF pickup in your shack.

73,
Don W3FPR

Re: K3 Which headphones for stereo cw work?

In reply to this post by k5oai

Sam,

While popular, the amateur grade headsets are very poor
quality and a poor value compared to good stereo headsets.

I found two very good headsets for mine. One type is a noise
cancelling Phillips headset I bought at a local Ace hardware
for $20, and the very best I have ever had are Sennheiser
HD280 pro headsets.

Both headsets sound great, block out room noise (even
without noise cancelling), and are most important very
comfortable. One feature of the HD280 pro is they have a
coiled cord that is long. This keeps the cord out of my way
and off the floor, while still allowing me to move.

For SSB I use a Sennheiser headset with attached electrets
microphone. It works perfectly with the K3 and reports are
it sounds excellent.

As for the "phase reversal technology", it only has a useful
effect in mono. It is just a phase reversing switch on one
earpiece. In stereo, it is meaningless because the K3's
audio phase between channels rotates constantly as frequency
is changed.

Mine are so much better than the headsets people bring over
for contests there is no comparison.

I focused on Heil, just because the are usually spoke of as the golden standard

I will consider them, although I thought the extra wide frequency response
might be a bit of a problem, even with the K3's rx EQ.

That brings up the point of my asking. Unless you're an unemployed younger
person, I doubt you will be spending 12hrs or sometimes more, under the cans.
Where as contesting hams sometimes to stretch the limits as far as number of
listening hours, and therefore might be better able to address the 'long term
comfort' aspect of my question.

hmmm, not sure how much I'm willing to have some more rf wizzing around the

Re: K3 Which headphones for stereo cw work?

In reply to this post by Bob Naumann W5OV

I have been using the CM-500 since Nov 2009 and on CW and SSB,now that we can have separate RX EQ per mode,its all you will need,set them up properly by your wish and pay only about $52 for them,like Bob said,its the best bang for the buck without a doubt.

Re: K3 Which headphones for stereo cw work?

In reply to this post by k5oai

Hi Sam,

Good questions for sure.

As I also agree IMHO the Heil stuff is over rated, for full bore 48 hour contests I use Bose QC-2 headphones.

http://bit.ly/9bXxL4

I find these to be extremely comfortable especially over 36+ hours of wear time non-stop. They can also be had cheap on the used market.
For me running SO2R I have 2 legal limit amps only about a foot away from each ear and I don't know they exist while they are on.

For more relaxed operating and having excellent quality I use Sony Studio headphones which you can buy for short $.

MDR-V6

http://bit.ly/b9sFh0

I'm a CW guy so a mic is not a requirement for me.

But if you like the Bose and want a mic there is this option as well.

Re: K3 Was - Which headphones for stereo cw work? Now - Audio Spread Spectrum

In reply to this post by Bob Naumann W5OV

This thread reminded me of something that I read back in I believe the
'80s. There was a circuit in which the CW audio was spread spatially,
i.e., the lower frequencies were heard toward your left side while the
higher frequencies were heard toward the right. The idea was that the
brain could do a good job of separating closely-spaced CW signals if
they apparently came from different directions. This would require
stereo headphones to implement.

With the advent of DSP this might be a mode that Lyle could implement in
the K3 if there was enough interest and if there was really an advantage
in this mode.

Re: K3 Which headphones for stereo cw work?

In reply to this post by k5oai

Since I work in pro audio, I have a selection of very good headphones laying
around. So far, everything Ive tried works with the K3. It all comes down to
creature comforts and, to some extent, their ability to reduce room noise.
The pro-quality in-ear earphones made by Etymotic Research and Shure are
better than most for both comfort and noise isolation. They are passive. I
also like my Sony MDR7506, and the comparable consumer version with a
different number that is otherwise identical. I agree with Tom about the
Sennheiser 280s, but the Yamaha CM500 is plenty good enough for me, producing
great contest audio, at about 1/5 the cost. And yes, anything with Heils
name on it is wildly overpriced.

Besides sealing out noise passively

For those interested in external isolation, I found a really neat website which compares noise isolation by frequency range. Select among 4 headphones you're interested in, choose Isolation Response and then click Compare for a graph of isolation by freqluency:

http://www.headphone.com/learning-center/build-a-graph.php?graphID[0]=1743&graphID[1]=533&graphID[2]=753&graphID[3]=1753&graphType=6&buttonSelection=Compare+Headphones

This shows some significant differences in isolation versus frequency. Bose, Sennheiser, Sony and Etymotic models are included but Yamaha and Extreme Isolation are not. Low frequency noise is most important in my shack due to amplifier fan noise but higher frequencies might be more important for a multiop phone environment.

I think you are referring to March 1999 QST, "Binaural IQ".

That effect is what the K3 AFX Bin mode is supposed to be, insn't it?
(For some reason though my ears can't hear the "spatial" separatoin.
It sounds different for sure, but I just don't interpret it as spatial
separation..)

No, but the jaw drop did occur when I was a kid with my first pair of
stereo headphones listening to the Rolling Stones psychedelic album
(forget what it was called...) I guess I was expecting something like
that from binaural IQ...

The funny thing with the K3 AFX is I can't decide if it sounds better
or not. It sounds better when I switch it on. Then it sounds better
again when I switch it off...

Probably too much di-dah di-dah in the noise has ruined my ear to
synthesized spatial effects or something...

The graph shows some interesting data for both impedance vs.
frequency and frequency response. It demonstrates why the
Sony MDR-6V are such favorites among CW operators.

They may not be much for low frequency isolation but the
frequency response and impedance/sensitivity (high) are a
very good match to the K3.

After doing a bit of looking I think the very low THD numbers on these
is also a big benefit. I've since looking ordered a set for Field
Day.

I have the same problem here,

switch on = (ah that's better)
switch back off = (hmm, that sounds better now)
then after about 2-3 more of those,
it's a case of.......
back in the MENU,
switch through the different settings for AFX,
can't really decide,
settle on one out of frustration,
just leave it at that setting and go on,
until the next time,

repeat often as required

resulting observation:
the K3 just sounds good,
no matter what I do to mess it up
