The impedance is way too high for normal audio use. And they have a microphone too. They run around 300Ω versus about 30Ω for consumer headphones. -- Len Sorensen

Fine question. I actually took this pair previously to ring audio, because of how this pair is constructed reaching wires is hard, save for the tip. The repair sort of worked around that issue, with my imagining the work has come undone. If you desire a visual idea then perhaps google jvc ha-s44x. They have been discontinued for some time now, but once in a while I find a pair...which reminds me to try newegg. Kare On Wed, 12 Jan 2022, Don Tai wrote:

Have you tried trouble shooting your existing JVC headphones? Perhaps only the audio jack has broken. Most traditional headphones are very robust, with their cable easily replaceable. With no microphone, there's only 3 cables. Of course if the ear piece foam or the metal connector between the two ears is broken, then you have no choice but to replace it.

Hi there, Fine and interesting list. To be sure, the idea of noise cancellation, or any variation's is a no, not just because of the sense of position, but because I have something talking in my ears when I use them in this particular setting..no phone ringing, door bells, or the all important music playing in the background. As I have been a radio producer, and professional singer for many many years, over the ear headphones are the most comfortable, speaking personally. I truly dislike earbuds, they tend not to stay in my ears, to put pressure on my ear canal etc...and the buttons are a no, mic interferes with the machine. The most important thing, for this particular set of headphones though is A combination of frequency range, sensitivity, impedance, and driver units...oh and input power. a few settings in the wrong direction, and the headphones will make me dizzy..literary. And those numbers can be device specific, what I will use for my reading edge, differs for what I use for production, or music listening, or whatever. It is part of why once found I may buy more than one pair. Cannot fault you for using the same ones since the 80's. Had a set once I got from radio shack that I used for more than a decade as well. Goodness but I miss radio shack. Kare On Thu, 13 Jan 2022, D. Hugh Redelmeier via talk wrote:

From past discussions, I know your shopping technique isn't like mine. But I'll mention my considerations on the off chance you might find them useful.

Most wired headphones are electrically / electronically interchangeable. Of course that's a good thing. It also means that there are a lot to choose from.

There are lots of issues of sound reproduction quality, but to be honest, all should have sound quality that is good enough for a reader (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:

- closed (i.e. they try to block sound from your environment)

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

- 5.57 ounces

- button controls (what do they control?)

- 1.2 m cable [the units are unspecified but 1.2 ft would be very short]

Do you use the buttons? What for?

I think "over-ear" means that these clamp on your ear as opposed to 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 circumaural, light, open [i.e. I can hear things going on in the room], good enough sound. They have replaceable cables and ear pads (but now hard to find). Out of production since 1986. I find that even these get uncomfortable after a while.

My current favourite is ear-buds. The ones with a selection of soft tips, not the hard ones. You can get decent inexpensive ones from China. 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".

TWS (true wireless stereo) headphones are amazingly convenient if you have Bluetooth. But you don't. There are a lot of adapters to convert analog to Bluetooth but I don't have any experience with them.

Greetings Karen, I would not find the model in the previous email. However, my two sense are over ear can mean different things. A current pair of headphones was stated that but it's more what Hugh was calling something else.

The other things were I normally prefer open backed as it's the only way to not screw around with frequency issues. I've my reasons. As to standard closed backs AKG, Sennheiser, Sony are the big good players from memory. I'm not sure of the site design for your needs so sorry :(. Your original pair was around 200 dollars from memory and they all have something good in that price point to my knowledge.

As to weight normally anything under 400 grams is fine for most people. And for impendance it should be 32 ohms or less if your not using an actual amp.

You may have better luck picking a few common brands and going to the manufacturer websites. Sony, for example, will let you select multiple models for comparison across features: https://www.sony.ca/en/electronics/headphones/t/headband-headphones FWIW, about 5 years ago I got a Sony MDR-7506 headset -- admittedly, not based on any sort of audiophile specs, but because I'd seen them used in recording studios and figured that was a strong point in their favor. I'm still very happy with it but with two small quibbles: (1) the cable doesn't detach, so it would be a pain to replace if I were to damage it, and (2) the material covering the pads degrades after a few years. I just replaced the pads with "Wicked Cushions" from Amazon, which are made to fit popular headset models. The Wicked Cushions are great so far.

Karen,

Open Backs have open grills or leak sound through the outer part of the

ear cups. They don't isolated sound the way most headphones do. You

don't see them outside of the audiophile market. The problem with

closing or isolating sound is frequency issues basically. Sound stage is

one big improvement on them as you can let the drivers actually breathe.

Most consumer amps in cellphones or whatever can get about 60-90 ohms if

your asking. So anything beyond that is not good. This is a problem for

IEMS in the audiophile market as they have to gear them for cellphones

actually so most are around 32-48 ohms from memory.

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. best, Kare On Fri, 14 Jan 2022, Erica Peterson wrote:

Hi nick, I still owe you a response to your note about cellphones, audiophiles, and in the ear monitors...imagine a scrunched face here. 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? Kare On Fri, 14 Jan 2022, Nicholas Krause wrote:

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. best, Kare

FWIW, about 5 years ago I got a Sony MDR-7506 headset -- admittedly, not based on any sort of audiophile specs, but because I'd seen them used in recording studios and figured that was a strong point in their favor.  I'm still very happy with it but with two small quibbles: (1) the cable doesn't detach, so it would be a pain to replace if I were to damage it, and (2) the material covering the pads degrades after a few years.  I just replaced the pads with "Wicked Cushions" from Amazon, which are made to fit popular headset models.  The Wicked Cushions are great so far.

Hi there,

You know something I have a hard time picturing what closed back

actually means.

to my imagination open back means nothing behind my head, which is my

preference. are closed back those behind your head then?

I agree on 32 for impedance..but sometimes they are higher. even with

no amp involved.

Kare

Karen,

Open Backs have open grills or leak sound through the outer part of the

ear cups. They don't isolated sound the way most headphones do. You

don't see them outside of the audiophile market. The problem with

closing or isolating sound is frequency issues basically. Sound stage is

one big improvement on them as you can let the drivers actually breathe.

Most consumer amps in cellphones or whatever can get about 60-90 ohms if

your asking. So anything beyond that is not good. This is a problem for

IEMS in the audiophile market as they have to gear them for cellphones

actually so most are around 32-48 ohms from memory.

Greetings Karen,

I would not find the model in the previous email. However, my two sense

are over ear can mean different things. A current pair of headphones was

stated that but it's more what Hugh was calling something else.

The other things were I normally prefer open backed as it's the only way

to not screw around with frequency issues. I've my reasons. As to

standard closed backs AKG, Sennheiser, Sony are the big good players

from memory. I'm not sure of the site design for your needs so sorry :(.

Your original pair was around 200 dollars from memory and they all

have something good in that price point to my knowledge.

As to weight normally anything under 400 grams is fine for most people.

And for impendance it should be 32 ohms or less if your not using an

actual amp.

Take care,

Nick

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.

Hi nick,

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

in the ear monitors...imagine a scrunched face here.

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?

Kare

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

May I ask for the full company name? Radioworld is a new one for me. I do agree, they sound like a fine resource! Cheers, Karen On Fri, 14 Jan 2022, Erica Peterson wrote:

Hi nick,

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

in the ear monitors...imagine a scrunched face here.

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.

best,

Kare

I don't see how impedance could have anything to do with making you dizzy. Could you explain? I'm not saying those headphones don't make you dizzy. But it would be very interesting to know the mechanism. If I had to guess at a factor that might cause dizziness, I'd pick problems with phase. That would imply serious filters, I'd think. Plain old passive headphones don't have fancy filters. Perhaps one driver wired backwards: that would make one signal 180 degrees out of phase. But that doesn't seem like an easy mistake to make. (It is easy on some home stereo's the swap the lines into a speaker.)

| From: Karen Lewellen via talk <talk@gtalug.org> | To be sure, the idea of noise cancellation, or any variation's is a no, I never suggested noise cancellation. That's a whole other kettle of fish. I talked about "closed" vs "open". Your existing headphones are "closed", according to the specs I read. That means that they block sound travelling through the outside of the cup. They block sound two ways: leaking from the headphone to the room and from the room to the ear. I thought that if you are using your reader, you might still want to hear what's happening in the room, albeit in an attenuated way. For example, you might want to hear other people in the room. Or you might not. That's why I mentioned closed vs. open as a choice. Nicholas had other considerations for the open / closed choice. They were beyond my experience or knowledge. | not | just because of the sense of position, but because I have something talking | in my ears when I use them in this particular setting..no phone ringing, door | bells, or the all important music playing in the background.

I imagine that's mostly about phase problems or artifacts of noise cancellation. If I understood correctly that this is for your Kurzweil reader, I suspect monophonic headphones would be fine. If you used the headphones monophonically, would that prevent dizziness? | And those numbers can be device specific, what I will use for my reading edge, | differs for what I use for production, or music listening, or whatever. | It is part of why once found I may buy more than one pair. | Cannot fault you for using the same ones since the 80's.

well..those must be free as no details show in a low graphics browser grin. Seriously, that is one of the pair I intend asking JVC Canada about. The specifications I need do not quite match, but that pair is just one of a series that seem to increase in sound detail. In fact, locating that pair gives me hope I can stay with JVC for this particular usage. Thanks, Kare On Wed, 12 Jan 2022, Lennart Sorensen wrote:

Actually, if I can search by brand it would help. For example, there seems to be a JvC series that replaced the one I am using right now...for one working ear at least. I have a soft spot for Sony as well, with the spec details what I need most and am not finding. Site the obvious?

I just noticed staples.ca has quite decent filter options. Filters include bluetooh, microphone, in-ear, over-ear, and on-ear and some other stuff.

They have these JVC wired headphones for example.
