I love my Scala 500 Bluetooth headset, but I’ve encountered a usability problem that I want to warn all you headset users about. Don’t put the headset in your pocket while it is turned on, especially if you use voice dialing on your phone. The button on the headset sticks out just enough that it is easily activated by accident.

I've had three incidents recently where I put the headset in my coat pocket while it was turned on and people were called. Fortunately it was my wife, parents, and sister in law that received the calls. Could have been embarrassing but nothing bad was said or heard. I've learnt my lesson and keep the thing out of my pocket when not using.

So beware, use the strap to hang it around your neck and don't put it in your pocket.
