If they come soon, they would be a winning combo with the Mate 20 Pro and it’s ability to Qi charge other devices.
I get why people buy into the Apple eco-system, they are very good at marketing. Personally I steer clear though. I do have some generic branded wireless headphones that are fairly good, cost me around £40, and do the job in a not so busy office, or for background music at the card table.
If I took the tube every day as @Liam_W suggests, then absolutely I would have noise cancellers.
Got to weigh up the pros and cons of each offering for your own use case I suppose.
Anyway, unfortunately I don’t know any hard evidence to suggest they are coming soon I’m afraid - although my wife would quite like a pair, so no doubt I will hear when there is more solid info.
