I've been using bluetooth for my right ear for about 3 years. While it's true that the AN was discovered in my right ear, it was very likely there long before I started using my bluetooth device.
I think there is more concern for those of us who have already lost hearing in one ear due to an AN since we have likely, myself included, moved the bluetooth to our only good ear. Unfortunately, the studies required to prove that these devices cause hearing loss would take years to accomplish, and by then for most of us it would be too late.
I see many people walking around malls and places of business that appear to be permenantly attached to their devices. For me, the only time it's on my ear is when I'm in the car. My cell phone is really only used very rarely. We still use a normal house phone when we are home, although that too is wireless and transmits a signal to the base station.
Lots of things to think about, but I don't think I will change my habits any based on the litigation or unsubstantiated claims.
My 2cents.
