Are those good specs though RHF for dxing?  Anyone in the knows here?  I don't
want to get a pair of phones that aren't good for long sessions of dxing.

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

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

jack' for my external antenna jack that I can leave plugged in.*****

thanks rhf:-)

I wouldn't know exactly what numbers to look for Starman.  What about the
numbers on the one RHF posted?

Koss are VERY cushy - they use foam covered with leatherette.

My Pro-120's did too, but the leatherette wore off, now I just have foam.

Didn't catch the brand you've got, but some (many?) manufacturers carry
replacement ear pads.  For Sony, you'd better be sitting down when they
tell you the price.

     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.

I use hi fidelity headphones and enjoy the sound from my radios.
Sony MDR-V600

They are the big around the ear type and very comfortable for long
periods of listening.
