What’s the Life-Expectancy of Bluetooth Headsets?

I bought this Motorola S10HD Bluetooth headset in 2011, but didn’t get into really using it until the past five or so months (primarily because I wasn’t impressed with how clumsy the pairing was). So now I only use them with my iPhone, mostly to listen to podcasts. I love not having to be tethered to my device and started using it every day. Well, until this morning when clicking the power switch did nothing. It’s a little recessed rubber switch that isn’t easy to engage. And now apparently it cannot be engaged rendering the device useless. Damn. I guess the life expectancy is much longer as long as you don’t actually use the device. Once you fall for the daily use trap, then the life expectancy is about the same as the common house fly. [fail trombone]
