Has anybody tested hollow airtube headsets/earphones??
If you own an air tube headset, would you be so kind as to share your experience&opinions? Which ones do you like(brand)?
About air tube headsets:
"The Air Tube Headset for the cell phone keeps radiation away from the head by using a hollow “air-tube” to transmit sound from a speaker located at a distance from the head. "
"ERT is a proprietary subtle physics technology that reduces effects of EMR by restoring and maintaining intercellular communications that are otherwise disrupted by EMR exposure."
It's obviously about radiation&health. I care about health, BUT, i also care about SOUND QUALITY!
