I mean, even if i said something like "Can you go into detail about mu-metal shielding; e.g. hard numbers, peer reviewed research, etc?" It still sounds like I'm calling bullshiat, because i am.
I'll leave it alone now. I don't expect that the question will be asked, and i don't expect that it will receive a substantive answer if it is.

If you do a search you will find this info in some documents he had published on the subject in the website and on his website...IMO if something is harmful to you, and you find a way of reducing it 98% of that value, what is the harm in doing that? BTW they are not charging you extra for that, it is just a bonus they gave you. FYI and from their website, of course there should be a lot of more info that we will not even understand, but we can ask him, but respectfully, he is a professional with 15 years of experience and reserach in that field:
ULE-technology / PROline:
PROline stands for Ultra Low Emission (ULE-technology) and offers a reduction up to 98% by using MU Metal. ULE also means significant benefits for professional users as it is highly-developed and specially designed for professionals.
ULTRASONE´s ULE-technology (PROline series) offers the lowest radiation of low frequency fields. Medical research has shown that magnetic field emissions can be hazardous to your health. The average magnetic field emission of headphones (without LE or ULE) is more than four times the maximum recommended levels. As ULTRASONE´s philosophy is not only based on perfect sound but also on protecting your health we managed to develop a revolutionary MU-metal-shielding method.
This patented and certified ULE-technology can significantly reduce risky magnetic field emissions up to 98%!
The ULE-technology is recommended by Technical Surveillance Organisations and Consumer Advice Centers with certified lowest magnetic field emissions.
Unfortunately guidelines for low-frequency magnetic emissions for headphones are still pending. Nevertheless, it is on one´s own responsibility to always minimize risks of damaging your health.
Electro Mag:
Some more information about electro magnetic radiation:
Electronic equipment emits low/high frequency magnetic/electric radiation, which is also called Electro-Mag. Electro-Mag is assumed to be harmful to our health. This is proved by medical research all over the world.
In order to protect health of people working within an electrically surrounded environment, clear limits about the maximum radiation emissions have been occasionally defined. For example in the TCO '99 for the allowed magnetic emission of computer screens, in a distance of 30 cm, a maximum of 200 nT (nanoteslas) is the upper recommended limit.
Recommendations for the low-frequency magnetic emissions in case of headsets and headphones are still pending or are not really in the focus of importance yet. This is quite surprising as every user is carrying this very emissive equipment directly on his head! Nevertheless, we note a rapidly increasing demand for shielded headphones and headsets.
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;in irresponsible cases even more than ten times the maximum!
The developed and patented PROline technology from ULTRASONE brings magnetic field emissions of headsets and headphones down to less than 90 nT.
