I think they look like really awesome earbuds and my first thought was "I am SO getting those", but I'm kind of leery of them because apparently they communicate with each other by transmitting THROUGH YOUR HEAD. I haven't been too afraid of bluetooth, but a constant and continuous path of low-level microwaves through your brain just sounds like asking for trouble. The best I can find by reading news articles is that some scientists say it's fine because it falls below the FCC's standards for safe exposure and others say that the FCC's standards are woefully low and mostly influenced by the companies that want to sell these devices. I'm no conspiracy theorist and I love my phone and ipad and I even have a bluetooth pair of earbuds (though they are wired to each other, hence hopefully not shooting signals through my head). Anyway, I just hope these things don't hurt people. Plus that W1 chip seems pretty awesome.
