I had some of these Bluetooth earbuds that cut out now and again with an Iphone X but were still useable. I now have an 11 Pro Max and the earbuds are now totally unusable. They cut out every few seconds so have returned them. I googled last night and read that it may be the modem in the 11 Pros causing interference with all bluetooth earbuds. I am also using the activity app on my watch 4 when it cuts out.
Has anyone got a set of completely wireless earbuds that actually work with the 11 Pro? They need to be the ones where one earbud pairs to your phone (master) and the the second bud (slave) pairs to the other earbud.
