Bose Headphones (noise cancellation) for Hemi-sync- good or bad?

[Jlrchrd2]

I got some Bose headphones the quiet-comfort noise cancellation kind. They use a triple A battery for the noise reduction part- I'm guessing they work by canceling out the frequencies of background noise. I was wondering if the ECM field of the battery would have any affect on health/overall brain wave pattern of my own? I know this is a silly question and it won't really change the amount i use them or whatever. Just more curiosity than anything. They are pretty amazing to use for hemi-sync and binaural beats but it seems a battery running that close to my head for as long as i use them might have some negative aspects? i don't know i might just be super hypochondriacing right now ha. Anyways let me know your thoughts- if you have any!

Microwave transmitters are not so good if set-up too close to your body. This audio device is not a microwave unit so there's nothing to worry about.
You can use it 24 hours a day for 20 years and it's effect will be a million times less dangerous than a 5 second call on your cell phone.
I've had EMF radiation burns and the power level then was hundreds of times greater than a cell phone.
Just putting things into perspective for you.
Your safe...

 I use Bose Noise Cancelling Headphones when I do sessions with my Laxman Light/Sound Machine and when I listen to Binaural Beats and Isochronic Tones.

They are great to have when the music or session stops. You are still left in total silence!
