Apple CEO Tim Cook confirmed an important feature of the upcoming Apple Watch – it’s ability to play music without the need for an iPhone.

Cook revealed the following in an interview with Charlie Rose last night.

It requires an iPhone, because they’ve been designed to work together. However, if you go for a run, and you don’t want to carry your iPhone, music is also on your watch. So with a Bluetooth headset, you can run and listen to your music without your iPhone.
