I've had them since mid to late November. I have had no issues with them at all audio wise. But yesterday, they wouldn't turn off. And they're still not turning off. I have to wait until the battery dies and charge them from there. This issue hopefully will be corrected with a firmware update, but regardless, it's inexcusable to have a $150 product be so problematic. We should be getting the choice to return them for full money back in my opinion. Or they should simply admit they've messed up and give us some sort of credit to purchase another, working set.
