Since Quarantine I have taught a lot of lessons on zoom. Even though I have a fully equipped studio with good quality headphone and microphone, I find myself go back and use airpods at the end. With singing we need so much movement it's just so much easier to do. Most of my students use airpods too.
Gradually I noticed I started to have headache constantly but can't understand what causes it. I try to cut coffee, go to bed early but the headache doesn't seem to go away.
Yesterday I was just casually asking a student on zoom that why she uses the traditional earphone instead of airpods (I know she does has airpods). She mentions to me that Airpods do emit radiation. It causes headache. I suddenly have an A-Ha moment!! The student only uses it for their lesson and I wear it constantly!!
So I did some research and found that that Airpods do emit electro magnetic fields. It results in the EMF radiation signal going directly through the brain.
However there is still a lot of argument online. There is no certain way to know for sure. Some people argue that it's possible that AirPod headaches are a result of pressure building up inside ear canal.
I still think airpods is one of the greatest invention, but just don't wear it for extend period of the time.
