Question Multipoint Wireless Headphones

[Jack10525]

I am trying to find a pair of in ear bluetooth earbuds that will connect to my laptop, ipad and iphone simutaneously. I do not want to have to disconnect from 1 device to connect to another. This is what I have found with the last 4 bluetooth earbuds I've purchaed from amazon in the last year. Is this not a real thing?

The basic issue/problem is that different audio plugs and standards are being used.

TS, TRS, TRRS.

FYI (Cablechick link):

For example, from the link, CTIA vs OMTP.

You are "mixing plugs and sockets".
