If we use Airplane mode in, say, the iPAD or iPhone, or simply disable wi-fi and bluetooth, would that be OK to use Earpods or similar headphones?

I mean, AirTubes are effective in terms of magnetic fields, so when we use over-ear headphones such as Sennheiser 598 SR or the Earpods even with Airplane mode (and using ethernet cables/adapters in the iPAD/iPhone) we are getting EMF?

Can someone explain this part? Unfortunatelly I don’t have a gauss meter here, and the AirTube I was thinking of buying, but I need some explaining if it’s justified, since I don’t turn wi-fi and bluetooth ON in my iPAD, and only use ethernet cables in it.

Has anyone measured the magnetic fields from Earpods / Airtubes and over-ear headphones?

Please post your opinion about everything I asked Smile

Hi Perene, Several people have questioned the general advice to use a wired headset. You might find these videos interesting (there are others on Youtube). I don’t think they would stand up to critical scientific scrutiny but they give an indication that there could be an issue here. The irony is that these would be easy and cheap to replicate in laboratory conditions with high precision meters, but no-one seems to be doing it.


And Lloyd’s take on air-tube headsets is on the main site here
https://www.electricsense.com/…..sets-work/
At least the air tube protects the ears and brain, even if you get radiation from the wired part.
Also, Dave Stetzer, Magda Havas and Trevor Marshall have all found microwave signals on power lines or mains wiring – presumably leaking from cell towers, smart meters etc.
I can’t comment from personal experience as I do not use a cell phone.
There are more videos on Youtube which look at magnetic fields from headphones etc. but I have not seen very much information about them or how strong they are.

Hi
This link seem to suggest there’s reason for concern

https://besynchro.com/blogs/bl…..headphones

The problem with it is that I am not talking about bluetooth headphones. And these tests weren’t conducted with Airplane mode on, as far as I know. However…

https://www.head-fi.org/thread…..00.557579/

And someone said this in a review:
https://www.amazon.com/Ultraso…..B003PJYBYE

*******
Very nice headphones. Good sound, and the magnetic field generated by these is very very low (I tested with a Trifield meter). Its great to be able to listen to headphones without being blasted by high levels of magnetic fields right next to my brain.

One serious shortcoming which should be easy for Ultrasone to correct is that the top head-padding on the headphones is inadequate. It is just too thin and narrow to do the job, and after a few hours of wearing these Ultrasones my head hurts from the weight.

For an example of headphone pads done right, see Sennheiser’s headphones (although the EMF level from my Sennheisers was very high and I no longer use them for this reason.) which have two big soft pads, one on either side of the top of the head.
********

There’s also the fact the Trifield 100XE is not reliable AT ALL, it’s a dinossaur meter that should not even be allowed to be sold anymore. But even that meter indicates there’s something wrong, or we are reaching the max levels recommended for magnetic fields.

OK, I decided to try the Air Tube headset and will see if I can get a reliable EMF meter to measure the magnetic fields. I have the Cornet ED88TPlus, but as you know it’s also not reliable AT ALL, only for measuring RF.

*****
P.S. This thread also suggests high magnetic fields, but it’s old:
https://www.head-fi.org/thread…..on.473894/

What I was looking for was someone measuring headphones with reliable gaussmeters like the UHS2

***** Update:

I just bought the UHS2 and the “EMF Radiation-Free Air Tube Stereo Headphones / Earbuds”. Once I get them I’ll see if the readings change.

Yes, the air tube headset is a good idea for reducing a cell phone user’s exposure to dangerous radiation. But will it prevent those near the user (e.g. chidren, the unborn) from being exposed to radiation from the same cell phone?

Here’s a review I posted about this product:

https://drive.google.com/open?…..OWrfPnaMIV

Manual:
https://drive.google.com/open?…..hk1I-I8BVB

Note: about the magnet part I noticed the same thing with another headset (from another company). Not sure if all air tubes have this issue, it’s worth checking.

******
Don’t buy this if you want to lower your total electromagnetic field exposure. This is marketed as an “Anti Radiation Headset” and indeed it does have air tubes from about your chest to your ears. That’s probably progress, but for some strange reason they have put magnets in the backs of the ear pieces to hold them together when you aren’t using them.

I think that most people buying this would not want to add an unneeded magnet 1″ from their brain. The magnet screws up the whole point of buying this headset. Why in the world did they do this?

I have a gaussmeter (UHS2, from AlphaLab) which cost me US$ 289 (way better than Cornet in what it does, since the Cornet doesn’t measure magnetic fields any closer in terms of accuracy). My bedroom measures 0.07, no more than 0.10, 0.15 mG, which is VERY LOW (most houses have less than 0.5, which is ideal). When I approach one of the headphones above and close this EMF meter the number goes as high as 0.5, 1 or even 2 mG, which is already extreme.

I guess they forgot the fact there are three kinds of EMFs: RF, magnetic and electric fields… and magnetic fields are considered even worse than RF.

Also the hadphones kept falling off my ears, and my face is 100% normal size. Either that or after a while it bothers me, as if there was a little more pressure than usual (we need to force them into our ears to avoid falling). These aren’t comfortable as the Earpods, not even CLOSE.

The manual is useless (so was customer service when asked) since it explains nothing about how can we remove the “rubber noise isolating ear tip” or the “rubber ring” that come with the product. It comes with additional sizes of these two, and a peg to hold God knows what.

The manual says there are three sizes, the default that comes with it is “M”, but there’s also “S” (smaller) and “L” (larger).

I won’t risk damaging these since I tried taking out and the rubber won’t budge. If I force this thing to come out I have no doubt it will harm the product. I was going to replace to check if comfort would improve (which I seriously doubt).

Also the sound quality is not great… I noticed right away it leaves something to be desired.

I’ll stick with wi-fi/bluetooth off (and/or Airplane mode) and some distance of my products to avoid high magnetic fields… investing in air tube headphone is a waste of time.
