Most Bluetooth headsets have a range of only 10 meters (30 feet). This also means that they emit far less radiation than cell phones themselves. ... That's why most authorities explicitly advise using hands-free devices including Bluetooth headsets if you're worried about radiation exposure from cell phones.The RF of any wireless device -- a cell phone, Bluetooth headphones or a wireless router -- emits non-ionizing radiation. These devices aren't as dangerous as those that emit ionizing radiation, such as X-ray machines, but some experts remain wary of them nonetheless.Yes, it's true that wireless Bluetooth headphones emit radiation. It's also true that Apple sold an estimated 28 million pairs of its iconic AirPods last year—and that there's not a ton of long-term research on the safety of this type of radiation.However, the few studies looking at the technology have found that it is safe. For instance, a 2014 study in The Laryngoscope journal found that, unlike cellphone radiation, Bluetooth radiation was not associated with any reduction in auditory nerve function in humans.
