Got my hearphones about 4 hours ago. No,issues connecting to my iPhone X. After playing with the controls for a few minutes I headed to check them out in a restaurant. Wow much better than I ever expected. I could block out the noise and hear my wife across the table. This was amazing!
One thing that I found out that no one has mentioned is that I can read battery status on the iPhone. Also, I find it annoying that it takes so long to load the control program each time I want to make a adjustment. Someone might know how to get around this.
