Risk is dependent on exposure level.  The more power involved, the
greater the risk.  An excellent comparison is microwave ovens vs WiFi or
Bluetooth.  The power levels used in the ovens are without a doubt
harmful.  The levels in WiFi and Bluetooth are below what's considered
safe.  Please remember you can never prove anything is safe.  You can
only fail to show risk.  Also, the risk from microwaves is not cancer,
as that is non-ionizing radiation, unlike ultraviolet and X-ray
radiation. There may be problems caused by heating etc.

That may be due to who you're talking to.  ;-)
Actually, some phones have very poor audio quality, which may trigger
headaches.
