![]() I fail to see the reasoning behind this move - nobody needs bluetooth earbuds that have a range of close to 70 meters. ![]() A regular phone on the LTE network transmits at 125mw - not much difference there, either. To put this into perspective: 100mw is what a WiFi access point uses - and nobody in his right mind would put one of these on each side of the head for hours a day. Class 1 devices can transmit at up to 100mw - so the Airpods potentially output an EM field that's up to 100x stronger than that of a regular bluetooth headset. However, Apple in their infinite wisdom have decided to make the W1 chip that's in the Airpods (and some Beats cans) a Bluetooth class 1 device. ![]() ![]() I use Bluetooth devices, including headphones, all the time and I'm not worried the least bit about those - but these things use BT class 2 or 3, which means the transmit power is at 10 or 1mw max respectively - which is, indeed, very low and almost not measurable on SAR measuring devices. I've decided to auction mine off before even openen them due to concerns with the TX power level these things use.
