I have had some success using Airpods with my Apple watch. Here is what I do.
1. I remove one of the Airpods from the charging case, and set it down on the table. It is important to not put the Airpod in your ear at this time.
2. Go to the watch face and flick up twice to open the control panel, double tap the watch face.
3. Flick right until you hear air play. Double tap the watch face. 4. Flick right until you hear Airpods. Double tap the watch face. 5. Now you can put the Airpod in your ear. The focus will stay on the Apple watch as long as you do not use the iPhone.
The quickest way to change the focus to the iPhone, is to do a two finger double tap on the screen to start music. The focus will switch to the iPhone almost immediately.
In order to change the Airpods' focus back to the Apple watch, you must remove the Airpods from your ears and repeat the above steps.
It is not elegant, but it does work.
