evidence: There is currently insufficient evidence that wireless headphones pose enough of a health risk to stop using them. People who are concerned can limit the hours that wireless headphones are worn, use alternatives like speakers when possible, and seek guidance from qualified health professionals. [...] There are two categories of EMF exposure: non-ionizing (low-level) and ionizing (high-level) radiation. Sources of non-ionizing radiation include power lines, microwaves, cell phones, and WiFi routers. Bluetooth wireless headphones fall into the non-ionizing radiation category. [...] Bluetooth wireless headphones emit relatively low levels of radiation compared to devices like cell phones, with power density exposures estimated at 10-400 times lower, according to a peer-reviewed study published in 2019 to inform public health guidance. Using wireless headphones for a call, instead of putting a cell phone directly against the ear, has been proposed as one potential way of limiting EMF exposure from cell phones.
