Plantronics Backbeat Go2

These look like they could be a nice replacement for my old broken Sony HBH-IS800's

Weird....My Stereo Sony hbh-is800's are working again!

Strange... they've been sitting in my draw for over a year without use as one side stopped outputting sound... Thought I'd give it a charge and test and low and behold it works again! Lets see for how long....
