Last year Misfit, a company best known for the attractive Shine health tracker, surprised us all when it introduced a smart light bulb at CES. And this year it's got another shocker: A smart wireless headphone dubbed Specter. It's got all of the usual fitness and sleep tracking technology as Misfit's other gear, but from speaking with reps it doesn't sound like the company intends it to be a primary activity tracker. Instead, Misfit could eventually use Specter's accelerometer for other applications. It's also compatible with Link, the company's app for programming a wide variety of functionality, like taking a selfie with your phone.
