Will earbuds work with my apple watch?
How can I get my plantronics bluetooth earbuds to work with my applewatch to answer and speak on the phone through the apple watch?
Hi
For making and receiving calls, Bluetooth headphones need to be paired to your iPhone, not to your watch.
(Bluetooth headphones can be used with Apple Watch for listening to music).
