Bluetooth uses radiofrequency energy.
EMF means electromagnetic fields. These occur around electrical devices and in nature. Bluetooth uses non-ionising radio waves to carry audio to your headphones.
A sticker’s appearance or placement cannot establish protection. Product-specific evidence of radiation reduction or health benefits has not been provided for EMF Protection. Research from Aires applies to its own technology.
For background on EMF, see NIEHS. For guidance on devices marketed to reduce wireless exposure, see ARPANSA.
