... ear version for a year now and it is great for phone calls

I've had the single ear version for a year now and it is great for phone calls. I've never had a problem except in really noisy areas. I decided to try these for music as I wanted the completely wireless experience especially while flying. They work, as others noted they don't do well outside or in large indoor spaces like an airport. One or both units drop out frequently when you turn your head or stop working altogether. I can't take the dog for a walk with them. This I think is more the technology than the product. I have issues some times using other bluetooth headphones while outside. I also had one of them go into some kind of fault and would not turn off (a particular issue with these I've had, could be my big fingers). There was a buzzing noise and no music. I let the battery die (which seemed to take longer than when in use) and after recharging have worked fine. The battery life seems poor. On more than one occasion I believe they were fully charged and they died after a short time. I did expect more from these based on my previous experience, and I am disappointed in them. I would not recommend these and I'm not sure I would trust this company to buy other products. In doors in the office or at home they work fine. For airports, costco, and outside I would suggest something else.
