please don't put this to the same level as those complaining for yellow tint screen/ QC issue.

Yes, it's very different. Those complaints are from people who actually believe they have an issue. You just wanted to discuss the dangers of something you have no intention of owning.

lol tell me when you get a brain CT in a few decades

WHO categorized cellphone as possibly carcinogenic....now we can easily mitigate its effect by putting some distance between you and the cellphone but you can't do that with "headphones" by the virtue of its design..

please don't put this to the same level as those complaining for yellow tint screen/ QC issue.

we don't know what we don't know is all I'm saying.

While I get where you're coming from, I think you are comparing apples to oranges. WHO categorized cell phones as a possible carcinogen, meaning that their evidence isn't conclusive enough to say that it is for sure. Inconclusive evidence dosnt necessarily mean that cellphones are safe, but certainly doesn't mean they aren't safe. With cellphone usage running rampant for almost 20-30 years now, I would think there would be some sort of evidence of an increase in brain cancer, but there hasn't been.

Now cellphones have, by in large, been deemed safe and there is little evidence to prove otherwise. Cellphones have SARS ratings anywhere from 1.1-1.6w/kg (2w/kg in some other countries), and while some people may mitigate the effects by holding the phone away from their head, most people do not. The majority of society put that phone right up to their ear and talk for many hours throughout the day. Headphones on the other hand have a SAR rating between .0001w/kg and .4w/kg (in the case of the Airpods it's .4 due to the increase of range). Even on the highest end, it's still drastically lower than a cellphone.

So while you may have Airpods in your ear more consistently and for longer than a phone, the radiation levels produced are much lower than a phone. If phones have been deemed safe by the majority of science, then headphones would be even safer.

About what was discussed in this thread there are lots of compiled data I recommend you guys read, they are enlightening:

This is a good start:
https://sites.google.com/site/understandingemfs/

And so are these books:

- Cell Phones - Invisible Hazards in the Wireless Age - 2001
- The Sick House Survival Guide - Angela Hobbs - 2003
- Public Health SOS - The Shadow Side of the Wireless Revolution - 2009
- Living Safely with Electromagnetic Radiation - Jim Waugh - 2010
- An Electronic Silent Spring - Katie Singer - 2014
- Unplug - How to Survive and Thrive In a Wi-Fi World Gone Wild - 2015

Others are also recommended in that Cecelia Doucette website. "Public Health SOS" is very good since it has questions and answers.


For the record, I uploaded today a video where I measured an iPhone 5 and iPAD 4 (wi-fi only), plus a Kindle Paperwhite and the DS4 controller (for PlayStation 4), using the famous Acoustimeter. I don't have the Airpods since I sold them for this reason and the fact I didn't like some aspects, such as having to recharge (or doing this often) and the battery not lasting as I wanted.

The difference between my video and all others available out there is explained in the description. I'll reproduce what I said in it here. What I want to point out is that if you are concerned about the Airpods you should be a lot more about the devices themselves.

(Before I forget, in case you haven't read it's possible to use ethernet in the iPhone/iPAD):
https://forums.macrumors.com/threads/has-anyone-tried-using-ethernet-on-ipad-pro.1974288/

However I am still not convinced about radiation emitted from the iPhone/iPAD under normal use. I bought another EMF meter (Cornet ED88T Plus) and once I receive I'll take more measures. I find this strange because at least my iPAD PRO 10.5 is not emitting radiation while I use the wi-fi and bring the Acoustimeter close to it (the readings don't seem to increase), only in iOS internal settings when scanning for a network.

*************** Video description ***************
Measured in this video (recorded in July 6, 2018):
1) My bedroom
2) Kindle Paperwhite 2015 (3rd generation)
3) iPhone 5
4) DualShock 4 (for PS4) joystick (CUH-ZCT2U)
5) iPAD 4 (wi-fi only)

This was a rare situation that provided me with the perfect opportunity to record this video. My building had a power outage, so all neighbors living above me were not emitting any radiation. It's important to note the neighbors that live close in the other building (not very distant from where I am - and not close enough to affect my readings) didn't suffer any blackout, that's why when the Acoustimeter pointed at the window it still read something. The levels were very low and close to zero inside my house. I used emergency backup lighting. While the video is not very clear you can see the following:

- The iPhone emit the most radiation, even at some distance it's still VERY high. In my view putting any cell phone directly into our heads is suicide. If the levels are that high at a distance most people use speaker phone, imagine if you hold these devices even closer?

- With wi-fi enabled in both the iPhone and iPAD, Acoustimeter levels don't change for a while (meaning these devices don't emit radiation ALL THE TIME, 24/7), and then after a few seconds the levels rise a lot, and drop again to previous readings which were close to zero. It is known the weaker the signal indicated on the cell phone/tablet display, the stronger the signal they put out. Considering everything was offline at the moment of this test, it's a strong possibility this is exactly what happened.

Note: If we go to the iPAD/iPhone wi-fi and bluetooth iOS internal settings the radiation levels will be the highest because in these all Apple devices will show you the devices nearby, after scanning for them. And the Acoustimeter will start an incessant beeping noise in the Bluetooth iOS settings, if enabled. We don't hear anything with bluetooth enabled outside of iOS internal settings. That gives validity to the theory that despite not finding any wi-fi router nearby the devices keep trying to establish a connection, searching for one every few seconds.

Further tests need to be conducted with a tablet/smartphone already connected to the internet and with bluetooth enabled. And also a video where I show the readings in the iOS internal settings. Stay tuned for this.

- Bluetooth in the iPhone 5 alone (go to 8 minutes and 20 seconds) as long as it is enabled it's emitting 3 times more radiation than the DS4 controller.

- Kindle Paperwhite: also very high levels while trying to connect.
