According to Apple's Watch site, you can accept calls on your Watch and, optionally, route them to your iPhone or to your Bluetooth earphones. I'm not quite sure how this would work -- would the Bluetooth earphones be paired with the Watch but not to its iPhone? I suppose if the Watch is already paired with the iPhone, the earphones would be too as soon as they were paired with the Watch. However the pairing works out, it seems the Bluetooth earphone/earbud/mic marketplace is about to get a significant boost. That is, if indeed it will be possible to take calls using Watch and earbuds (with build-in mic) only, not having to physically access the iPhone you've got tucked away in your briefcase. Am I missing something, or is there a Bluetooth earphone in my future, along with iPhone 6 and Watch?
