are those 1.5 tesla Beyerdynamic drivers a concern?
thats 15000 gauss equivalent
I think it comes down to the engineering.. in order to get incredible Tesla level rating (in Beyerdynamic Tesla models), the field control, to get the power to ‘that level’ was ’great engineering’.
Having seen the way they did it (essentially super controlled magnetic field that gets a very specific zone up to that Tesla field level, by controlling the field and ‘using that cage’ to amplifiy the strength of the relatively small amount of magnet involved..), it has always been on my radar. -I don’t want that near my head and would simply rather use hifi and speakers if it means keeping my brain free from ‘field effects’. That being said, Beyer seem to know what they are doing, the problem is ‘the Tesla measurement‘ has been marketed and ‘lesser capably engineered products’ might just use ‘more magnets’ and ‘less effort‘ to control the fields….
Of note, some Beyer T90s I used were great, felt ‘lightweight’ and not fatiguing.
Last year I bought ‘quite a few planars’, and every set would send me to sleep nearly instantly. (I gather I must be sensitive to this stuff)
As I climbed higher and higher in the Planar world, every model just kept putting me to sleep.
I realised that the research I had read on Ultrasone products (commisioned by security agencies who would monitor using headphones for 12hours+ sessions, and had lots of infield agents ‘health issues’ to deal with), that had came up with ways to make ‘safe’ products; it isn’t NONSENSE.
To those sensitive to magnetic field sensations, the Ultrasone headphones I bought were so ‘unfatiguing’ that I bought more sets for the child and actively recommend them to many parents, as childrens’ BloodBrainBarriers are not fully developed and the ‘ear holes’ are ‘sans bone‘ that actually reflects many aspects of RF.
I do not encourage multipoint bluetooth buds IN EAR CANALs, and thenotion that bluetooth is looking to have 3-10x the range in product evolution is crazy…
250+ doctors approaching the World Health ORganisation to try and have some protection in place for ‘the masses’… (nope!)
I do use bluetooth, but prefer horseshoe neckbands that allow the aerials to be away from the brain..
Of note, the Ultrasones, whilst they have shielding and cleverly place the magnets well away from the ‘ear hole’ (s-logic), when plugging them into wireless devices, such as a playstation controller, they act like antennas and most people get nauseas within five to ten minutes of using them ‘cabled into the wireless controller’.
The effect is very prominent, and EVERYONE who has used them, without me mentioning anything, will pull them off and ‘need to go outside’ (for air) within a ‘super short amount of time’.
That is fairly unique to the Ultrasones (wired into wireless devices can make them very sickness inducing), but for all the rest of the time, they are the ‘least headphoney‘ headphones I have ever owned, and I feel fresh, like I am not wearing headphones at all, every time I use them…..
