May I ask for the full company name?
Radioworld is a new one for me.
I do agree, they sound like a fine resource!

Karen, if this is for a reader (not music), maybe you could visit (or email)
Radioworld and talk with them about their headphones and headsets?
Unfortunately there don't seem to be good product filtering options on the
website, but I would think they would be knowledgeable about the specific
parameters you care about.
Cheers,

Hi nick,
I still owe you a response to your note about cellphones, audiophiles, and

Speaking personally, one does not enjoy quality music on a cellphone smiles.
This audiophile uses a real stereo with real speakers with her real vinyl
collection.
To answer your question, I was given too much anesthetic during an eye surgery
resulting in a vascular accident to a very tiny part of my brain. In the area
that processes speech.
There are solutions, perhaps consult the book "the brain's way of healing." or
even the CBC special.
Anyway, one result is issues with some frequencies. Aside from headphones,
rather a few cell phones, even cordless phones create the same impact, I can
get dizzy, with some far far worse factors if exposure continues for a long
time.
My cell for example is a lg flip phone, not a smartphone.
It seems? that the closer to analog, the happier my brain happens to be.
Because I am a singer, some of the doctors discussed in the above referenced
book began healing this part of my brain, neural plasticity is a magical thing.
Could not finish due to expense at the time however.
Intend returning, with everything crossed staff with the Listening centre here
in Toronto remain well.
Long answer to a short question, but long before I had a solution, I was
choosing my audio gear very carefully, and my needs differ depending on the
device in question.
One set of headphone needs for my talking computer, another for my stereo, a
third for my portable Walkman etc.
Does this make sense?

That helps now. So your talking about wave form issues with digital conversion.
Most high
end DACs get rid of this. As for headphones, that would be some part of the
frequency not
sure what. Most really high end headphones don't have this issue. I'm not a
expert but
that's probably in the mid high to high frequencies if your talking core less.
It
seems that's my best guess. You probably want PCM 96khz or above at least to
get as close
to analog as possible if that's your comment. As you mentioned unless you have
a actual
good DAC, it's not going to matter here.
As for IEMs, the market is much better now. Sure it's not as good as true open
backed or
really, really high end loudspeakers i.e. Class A. I look at them more as it's
not terrible
from my very picky perspective for portable use. I'm very picky even more than
most of the
audiophiles I know. I was in the middle of researching my own vinyl setup
actually that
meets my standards. So far I'm figured out that moving coil is the only way to
go. Not sure
when it will happen through.

Karen,
What do you mean by dizzy actually? Normally that or fatigue is a comfort or
sound sensitivity issue.
For example, these days I've very sensitive to frequencies in the mid range and
mid treble. That's
about 400hz - 1khz and 6khz-10khz. You may want to figure out if your sensitive
to sound issues in
certain parts of the spectrum. Or perhaps you mean something else. This is just
my experience with
various people.
Good luck with your search through,
Nick

Hi Erica,
The Sony Mdr-7506 headphones have been a staple of audio production for
honestly decades. I got my pair in hmmm2004 or 2005.
However, this is a fine example of my personal issue...I cannot use them.
The impedance on this model is 24, and they make me dizzy.
I do have production assistants use them, and in all these years the ear
pads remain flawless.
That being said, I may be reaching out to Sony directly, as my e-mail
exchange with JVC is becoming rather frustrating smiles.

(as I understand it).
I would imagine that the main issues are comfort -- a very
individual
thing. Oh, and durability -- not something in the specs!
Here's what I glean from the specs of your old headphones:

- over-ear [I find such headphones uncomfortable fairly > > > > > > > quickly]
- 5.57 ounces

Do you use the buttons? What for?

clamping on your head around the ear ("circumaural"). I find
over-ear
very uncomfortable after a few minutes but I seem to be in a
minority.
Do you really want to have sound isolation from the room
("closed")?
I imagine "situational awareness" would be useful.
Out of habit, I use ancient Sennheiser HD430 phones. They > > > > > > > are

I have, for example:
https://www.aliexpress.com/item/1005002184896879.html
Currently C$16.84 without microphone. I paid less.
There are many other brands that are likely fine.
There is an enthusiastic following for "Chi-fi".
