EMF 50 HZ radiation from headphones SONY MDR-E818

"I use now Sennheiser cx300 2 headphones and they almost have no such effect."

Will you share the exact measurements? I'm interested in buying a pair of headphones that emits as little radiation as possible.

I can guarantee nothing to you. I am only amateur with several gadgets.

Problem is that best gadget I have is covering frequencies between 16hz and 100 000 hz. I don't know if this gadget covers all frequencies that are emitted. More :I think it depends which source of signal you are using: motherboard jack or maybe some portable player or something else. Measurements can be different on each source. But you know what, I will make a movie about it. Its good idea, thank you.

Does that mean that this set of headphones is somehow dangerous for one's health?

@steamerbg

I don't know, but I think it will be better if we had headphones without such side effect. One can easily suppose, that this radiation is taking part in injuries from headphones. Its good point to think about.

I use now Sennheiser cx300 2 headphones and they almost have no such effect. I can't tell you that I feel big difference. Maybe because I don't use them too much as teenagers do. I think some professional research is needed here. But we all know all modern "researches" )

All ur stuff is old

But I can say, that Sennheiser CX300II In-Ear Earbuds CX 300 are much better. Do you know something about other models? Post it here!

The strength of the mG really is not the issue it is more the frequencies. Some are harmonious some are not 50hz is not a particularly good hz..

[shidunce]

I didnt understand your words.

This device measure only 50 hz field and some frequencies aroud 50 hz. I am sure there are more signals at dif. frequencies, but I have no equipment to measure them (they must be in inteval from 1 hz to 500 khz?).

If you have any info about frequencies of EMF fields emited from such headphones, then please post it here.

@shidunce I have an ElectroSensor and am a radio tech. I have tested this device and can tell you it's not just sensitive to 50 Hertz. On a signal generator the peak sensitivity is at 200 to 300 Hertz but it will pick up anything from 30 to 4500 Hertz, depending on source power, tapering off at the high end. As such it easily picks up the multi-frequency EM field from the earpiece.

Thank You for your comment.

I wish I had more sophisticated equipment to measure signals and other frequencies, but now I have only what I've got )

All devices ,that emit electromagnetic radiation, emit it with range of frequencies, not only one.

If not a secret what is the pek mesurement you have on this device? (value in Mg or other?)

[shidunce]

When I am tired I can't listen via such devices - sounds seem to me strange, like I listen to high frequencies without bass.

But if I sleep well, I can listen to music, but not too loud.

About 12 years ago I knew someone who has very low tolerance to such headphones - after listening 3-10 minutes my firend each time got very very sleepy.

I can't use these for more then couple of minutes, I get a headache

[shidunce]

This model is pretty good. If you take some cheap 3 bucks headphones, then it can create 30 mG in your head.

I did not know that, thanks for the info.
