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.

SPECIFICATIONS:
• Frequency Response: 20-20,000 Hz
• Maximum Input Power: 100 mW
• Impedance: 60 ohm
• Nominal Sensitivity: 98dB
• Total Harmonic Distortion: 0.2% at 95 dB SPL, 400Hz and 1 KHz
Are those good specs though RHF for dxing?
Your 'best' DXing Specs are the ones for your Radio/Receiver.
Anyone in the knows here?
I don't want to get a pair of phones that aren't good for
long sessions of dxing.
Then - Think Comfort First.
produce dynamic sound and are perfect for listening
from your computer, MP3 or CD player
I use none of these, nor do I forsee it happening in the future.
I'll write down that cat.# and take a look.
See the Tip Above.
****right now though the most important thing to me is getting an 'extension
jack' for my external antenna jack that I can leave plugged in.*****
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.

A Shortwave Antenna is "Equally" Important for Good Reception [.]
