Query: Good product

Although I meant to order the non-vibrating headset, it is easy to turn off the vibrating feature, so I am fine with what I received. The only problem I have is that the battery doesn't have the life that the manual declares it should. The unit stays powered off most of the time, so I would hope that the battery life is retained. However, when I do turn it on, I can only talk about 20 minutes before it starts beeping. Not sure why this is.
