health issues associated with prolonged headphones use due to EMF pollution?

post #1 of 171
Thread Starter 
hi there, I was wondering...Ultrasone boasts about stellar EMF filtering: Ultrasone
Quote:
Within a research of 60 current headsets (1999 - 2000) ULTRASONE found out, that the average magnetic field emission of headsets is more than 1000 nT with a peak maximum of 2100 nT - on average. This is more than four times the maximum, recommended for computer screens in TCO '99
they even have some technical reports there: Ultrasone

apparently when you go through a MRI, you will also receive around 1 Telsa...and each time either my friends or I asked beyer, they were always playing dumb like "who's gonna use headphones for several hours in a row anyway?"

it's very nice that manufacturers keep on improving cell phones, but what about headphones? why does only Ultrasone care?

Well it seems that headphone can actually effect people with peacemakers. So if you have one don't place your headphone in your pockets close to the peacemaker.

"strong magnets in the tiny headphones" ..figures

BTW, beyer boast about having used the strongest magnets in the industry on the T1 I think? it's a joke, right? or do they also sell MRI machines meant as after-sales support?

T1 Press release

Quote:
The developers have now repositioned the magnets into a ring around the coil, allowing for a more than doubling of the magnetic flux density to approx. 1.2 Tesla.

maybe it's called tesla-1 for a reason? you're buying a personal MRI machine that happens to also play music basically?

Yea I have ordered them, I usually love beyer sound but I' m kinda scared lol.
Oh well for now I' ll just convince myself that my music is more important than some possibility that they may be dangerous

"you only live once"...might have never been so meaningful

There's a reason why only Ultrasone cares about this. The hypothetical health dangers of headphone radiation are the product of Florian Konig's research and advocacy. His word has it that we are the victims of EMF "pollution" that has numerous vague effects on human health. With no disrespect intended to Dr. Konig's headphone business, his contributions to medical research are about as suspect as Linus Pauling's orthomolecular medicine. Both make some superficial sense but fall apart when viewed in the context of modern medical science. And the Nicola Tesla namedropping on his advocacy site is the cherry on top.

Herr Konig himself said the standard for computer monitor emission is not perfectly relevant because it is particularly strict since eyes are vulnerable to radiation.

It's been several years since I looked at the literature, but I don't think more than a handful of people believe there are major health effects from the amount of emf you get from dynamic headphones, unless maybe the cable is also acting like an antennae and funneling emf into your ear canal, small warning if you decide to listen out of a cellphone. Cell phones can emit far more emf (they all emit different amounts), even then scientists disagree big time on whether or not that has any/small/big health effects, but studies on cell phones aren't relevant and studies have to be done on headphones before claims on their health effects should be made.

If you're really worried, just by one of these (EMF Safety Garments, Bedding, & Grounding Devices).

This has Patrick's name written all over it!

I don't see how magnets can cause health problems. People go through MRI's all the time with no problems (unless they have metal in them like plates or a bullet), and MRI's are much more powerful than any headphones.

I highly doubt the severity of effects from headphones, but magnetic imaging and radio imaging equipment exposure is limited to a few seconds a few dozen or so times in a person's life. Operators are required to get a safe distance / go behind a shielding wall while those machines are on for a reason - continual exposure over longer periods will have detrimental effects.

looks like a MRI can output up to 3T: mri tesla - Google Search
Quote:
The magnets in use today in MRI are in the 0.5-Tesla to 3.0-Tesla range
alright, I guess we'll never really know whether Ultrasone is hyping about non-issues to boost sales, or if the other manufacturers are just playing dumb because of inexistent safety rules.

if I liked the Ultrasone, I'd feel good using them...too bad I hated the Pro750 hah.

EMI polluting my brain... now THAT'S why I feel the need to keep spending money on audio equipment!

Very few people are afraid of static magnetic fields like you find in an MRI machine. What is usually meant is emf produced by alternating current.

Don't be afraid of emf from headphones, there's likely many other things emitting emf 1000x higher around you.

Sorry I already look geek enough without that on my head

The higher end ultrasone sound totally different but well its not the right forum to talk about that.
