What's the current state of knowledge concerning health risks caused by Bluetooth headsets?

What has been confirmed so far?

I lack the expertise to evaluate which reports are trustworthy and which are not.

Additionally, some people may suffer from hypersensitivity to the microwave radio frequencies, causing them to get headaches just from turning a phone on or being in a room with someone on a phone or headset. According to the United States Food and Drug Administration, the US Federal Communications Commission, and the United Kingdom National Radiological Protection Board, all available scientific research shows that mobile devices are safe, but further research is necessary.

  • @JasonStack questions need to be about notable claims, but there's no need to bring proof. On the other hand, it's clear that if a question is notable (i.e. if a lot of people believe that), then it should be trivial to find examples via a simple google search. – Sklivvz Feb 3 '15 at 0:51

  • Isn't this a duplicate of the other wifi/bluetooth/cellphone microwave safety questions? – Paul Feb 3 '15 at 22:40

    From the spectrum chart you included, below, WiFi and Bluetooth both operate in the 2.4Ghz band. Cellphones use a lower frequency that is still considered low frequency microwaves. The types of electromagnetic waves are very similar. One can argue about which is closest to your head, the typical duration, or whether there are other dangers. For instance, a headset of any type may distract you or break into sharp pieces during an impact (e.g. automobile crash with airbag deployment; bicycling/motorcycle accidents) – Paul Feb 4 '15 at 8:30

After some googling, this seems to be the current state of knowledge, which is not specifically about Bluetooth headsets but wireless electronic devices in general:

  • No negative effects of short-term use were found
  • Research on effects of long-term use hasn't been done yet or is in progress, respectively
