But using a cordless headset will not increase your risk of developing cancer, experts say. Apple’s new AirPods connect to the iPhone 7 via Bluetooth, a technology that makes it possible to transmit data over radio transmissions. Wearable fitness devices, which also transmit bursts of data over short distances, emit similar levels of electromagnetic radiation, Foster said. By comparison, the additional exposure to electromagnetic radiation delivered by a wireless headphone device was "probably about a thousand times lower,” he said. Other practices, including the rise of texting, have reduced the electromagnetic exposure many people get from smartphones, which can emit several hundred milliwatts of electromagnetic radiation when operating at peak power.
