Query: Wasn't for me

The power button is difficult to turn on and off, there's a delay between turning it on and it turning on so sometimes I would press the button a second time only to have it turn off on me (vice versa when I was trying to turn it off). The power button has a section that points up and hurt my fingers when trying to turn it on and off. I had a difficult time fitting the headset on my ear, it seemed to fall off frequently. In the end I decided to return this headset, too many negatives.
