I have a pair of PRO-25 titanium headphones that are quite nice and
they cost less than $40 new (I got mine used for $5 at a thrift store)

At Radio Shack, they have this pait of phones that are 99.99 that are made out
of titanium. They fit super and definitely 'felt' expensive. Anyone with any
experience with these. Would they be good for DXing?

I have the Optimus Pro40's and have worn out the inside foam part so I have
black electrical tape nicely encircled into it. But I definitely need some
news phones, and I looked at the others and they were junk except this one
pair.

Figures it's made out of titanium and cost $99.99
Is there something I should look at in the specs to bring back to the group?

I have two pairs of RS Pro-25's. I bought them for $19.95 each when they
went on sale every year. They have very good sound with low distortion.
They were made for RS by Koss.

Getting back to the topic, I still don't recommend full range (fidelity)
headphones for shortwave listening. They exaggerate the high frequency
heterodynes, if they can't be removed with a notch filter or bandpass
filtering on the receiver. You may not always be aware of those het'
tones but they can lead to listener fatique.
Some of the best shortwave headphones are the old ones with full ear
cups that use small cheap speakers. You can find them at garage sales
and flea markets. They have the kind of speakers found inside of
computer cases which make the 'beap' when you turn the computer on.

That's why I've always liked my 'el cheapo RS (Archer) 16 ohm phones.

Good voice quality.

I use none of these, nor do I forsee it happening in the future.

I'll write down that cat.# and take a look.

The specs are good for any kind of listening. For SWDX, or indeed,
any kind of long-term listening, the comfort of the headphones is as
important as the specs. Those headphones wil be plenty "loud" enough
with any receiver, and
the frequency response specs far,far exceed anything you'll need for SW
or MWDX.
Now if you listen to FM radio at all, the specs become much more
important, but those are still fine. The THD figures are also good.
Note you can buy comfortable headphones this good or better at a lower
cost - the titanium thing is, as someone else pointed out, a "buzz" word
selling device as much as anything.

For the record, I like cushy, foam cup phones for serious music
listening, but for radio DX of any kind (and I use phones 95% of the
time) I prefer the very light "on-ear" type. Mine are a $25 Radio Shack
pair, and they work great.

I think for SWL a speaker or headphone that rolls-off the highs at
frequencies above voice range is preferable to a full-range
transducer.

I agree. It's not really desirable to have full fidelity headphones for
shortwave listening. They enhance the high frequency heterodynes like
5-Khz, which can be annoying if you don't have a notch filter on your
receiver to remove those het's.

DX LUVER,

FIRST - Most Headphones today are made for Music Listeners who
want High Fidelity Sound Reproduction. For Radio use this means
FM Stereo Sound.

SECOND - For AM/MW and Shortwave sound reproduction a 'quality'
Headphone that can be used for FM Stereo Listening will do the
Job OK provided that it has a good long term Wear-ability Factor.

For AM/MW Shortwave DXing the Headphone's Wear-Ability-Factor
is Equal to the Headphone's Sound Reproduction Qualities.

For Me - The Headphone's Wear-Ability-Factor is usually an "ODD"
Number and Rating:

#1 = POOR - Less that One Hour and My Ears are 'Sore' and My Head 'Aches'.

#3 = GOOD - After Three Hours My Ears are getting Sore & Sweaty
and My Head is starting to Ache form the pressure of the Headphones.
(Lets me know it time for a Break from the Listening to the Radio.)

#5 = GREAT - After Five Hours My Ears are NOT Sore and My Head
is NOT Aching. (This usually means that I Missed getting up
from the Radio/Receiver and having a Meal )

THREE - About Headphones Sound Reproduction "Qualities:
"IF" you have a good AM/MW Shortwave Radio/Receiver that is a
real DX Machine with both Signal and Audio processing features.
Then the Radio/Receiver will be the "Limiting Factor" in the
Audio Chain and the Sound Level and Audio Reproduction that you
Hear on your Headphones will be a faithful reproduction of what
is being provided by your Radio/Receiver and nothing more.

IMHO: Personal Comfort and Wear-Ability is my primary Concern
in 'selecting' a set of today's quality High Fidelity Headphones
for Radio Listening and DXing.

TIP: Go to the RadioShack Store and Put them on your Head (Not
'plug' into anything.) and then walk around the RadioShack Store
for a Half-Hour and get the Feel of the Headphones on your Head.

NOTE: If you are not 'comfortable' Wearing the Headphone with
out any Sound for a Half-an-Hour; then they are not for you [.]

TBL: I trust to my Radios/Receivers to giving me the Sound Level
And Audio Reproduction that I need for Radio Listening and DXing.

BONUS - If you should want to do some FM Stereo Radio Listening
from a Radio that only has a Single Speaker / Mono-Aural Sound.
Then a set of quality High Fidelity Headphones are really Great
for doing some enjoyable Stereo Sound Listening via FM Radio.

Anyone in the knows here?

See the Tip Above.

****right now though the most important thing to me is getting an 'extension

FWIW: RadioShack sells 3Ft-6Ft Mono & Stereo Audio Extension
Cables that do the trick. You can use them as is or modify them
with a small Utility Box that several Audio Output Jacks to meet
your specific Audio 'connection' needs.

TIP: These same 3Ft-6Ft Mono & Stereo Audio Extension Cables
can be used for the External 1'8" Antenna "INPUTS" that are use
on many 'portable' AM/FM/Shortwave Radios. Leave it connected to
the Radio and connect and disconnect the Antennas for the other
end of the Extension Cable. (Save the Radio's External Antenna
Input from 'wear-an-tear'. Again you can modify this Cable with
a small Utility Box that several Antenna Input Jacks and Terminals
to meet your specific Antenna 'connection' needs. Also, you can
include some circuity to provide a small level of Radio/Receive
PROTECTION from EMF and ESD.

good post rhf, yeah I don't do the fm listening thing so that's not a problem.
I'll check out those Koss ones when I get a chance for 19.99 and see.
'Thanks again
